MARK PURNELL, Defendant Below, Appellant,
STATE OF DELAWARE, Plaintiff Below, Appellee
Submitted: September 24, 2014.
Case Closed December 9, 2014.
Court Below: Superior Court of the State of Delaware, in and for New Castle County. Cr. I.D. No. 0701018040.
Thomas A. Foley, Esquire, (argued), Joseph M. Bernstein, Esquire, Wilmington, Delaware, for Appellant.
Elizabeth R. McFarlan, Esquire (argued), Karen V. Sullivan, Esquire, Department of Justice, Wilmington, Delaware, for Appellee.
Before STRINE, Chief Justice, RIDGELY and VALIHURA, Justices.
Defendant-Below, Appellant Mark Purnell (" Purnell" ) appeals from a Superior Court Order denying his Rule 61 motion for postconviction relief following his conviction of the following offenses: murder second degree; attempted robbery first degree; possession of a firearm during commission of a felony; possession of a deadly weapon during commission of a felony; possession of a deadly weapon by a person prohibited; and conspiracy second degree.
On October 17, 2008, Purnell was sentenced to an aggregate of 77 years at L-5, 21 years of which were mandatory, suspended after serving 45 years at decreasing levels of supervision. Purnell's convictions and sentences were affirmed by this Court on direct appeal.
A timely motion for post-conviction relief (" Rule 61 motion" ) was filed on March 25, 2010. An amended Rule 61 motion was filed on October 11, 2011. The Superior Court referred the matter to a Commissioner for findings and a recommendation. On July 3, 2012, the Commissioner recommended that the Rule 61 motion be denied. Purnell filed a timely appeal from the Commissioner's findings and recommendations. On May 31, 2013, the Superior Court issued its decision denying Purnell's Rule 61 motion.
On June 28, 2013, Purnell filed a timely appeal in this Court from the Superior Court's Rule 61 decision. Purnell raises four arguments on appeal, all related to the performance of his trial counsel. First, Purnell argues that his trial attorney was ineffective under Strickland v. Washington  when he failed to request an
accomplice credibility jury instruction. Second, Purnell contends that his counsel was ineffective when he failed to request a limiting instruction regarding the guilty plea entered into by his co-defendant, Ronald Harris (" Harris" ), where the plea was entered following selection of the jury for a joint trial, but before the trial began. Third, Purnell contends that his counsel was ineffective when he failed to appeal the trial court's ruling denying his request to empanel a new jury following disclosure of Harris' guilty plea. Finally, Purnell argues that his trial counsel was ineffective when he failed to object to comments made by the prosecutor, which Purnell contends amounted to improper " vouching" for Harris' credibility.
We find no merit to Purnell's appeal. Accordingly, we affirm.
I. FACTUAL AND PROCEDURAL HISTORY
Tameka Giles (" Mrs. Giles" ) was murdered after a botched robbery attempt on January 30, 2006. She was walking with her husband when two men approached them and demanded money. After she refused, one of them fatally shot her in the back. Both men fled.
The police quickly identified Harris as a suspect based on eyewitness identification from Angela Rayne, who had been smoking crack cocaine nearby at the time of the shooting. Mrs. Giles' husband also tentatively identified Kellee Mitchell (" Mitchell" ) as one of the shooters in a photo lineup. The police arrested both men on February 18, 2006. At the time of the arrest, Purnell was in Harris' apartment, but was not yet considered a suspect. Neither Harris nor Mitchell identified Purnell as one of the assailants during any of their respective interviews with the police in 2006.
Purnell was not identified as a suspect until January 2007, when Corey Hammond (" Hammond" ) informed the police that he had seen Purnell and Harris together on the day of the shooting. Hammond had previously denied knowing anything about the crime, but suddenly recalled that Purnell had complained about needing money and was carrying a firearm on the morning of January 30, 2006. Hammond also informed police that Purnell had later bragged about killing Mrs. Giles. As with most of the State's witnesses, Hammond's credibility was an issue: his statement to police followed an arrest on drug-related charges, and the State agreed to reduce his sentence in exchange for his trial testimony.
Also in January 2007, Mitchell changed his story and informed the police that Purnell was involved in the shooting. He recalled a conversation in April 2006 with Purnell in which Purnell confessed to shooting Mrs. Giles. Mitchell's girlfriend, Etienne Williams (" Williams" ), also claimed that she had overheard Purnell confess during a telephone call.
Based on this evidence, the police arrested Purnell. In April 2007, Purnell and Harris were jointly indicted on charges of murder in the first degree, attempted robbery in the first degree, conspiracy in the second degree, possession of a firearm during the commission of a felony, and possession of a deadly weapon by a person prohibited. A jury was selected for the trial on April 2, 2008. Five days later, before the trial began, Harris accepted a plea deal from the State. In exchange for
pleading guilty to reduced charges, Harris agreed to testify against Purnell. The trial against Purnell began on April 14, 2008, with the same jury initially selected for the joint trial.
The jury voted to convict Purnell of murder in the second degree, attempted robbery in the first degree, possession of a firearm during the commission of a felony, possession of a deadly weapon during the commission of a felony, possession of a deadly weapon by a person prohibited, and conspiracy in the second degree. Purnell was sentenced by the Superior Court to an aggregate of 77 years at Level 5 incarceration, 21 years mandatory, suspended after serving 45 years at decreasing levels of supervision. Both the conviction and sentence were affirmed by this Court on direct appeal on August 25, 2010.
Purnell then filed a motion for postconviction relief under Rule 61, alleging ineffective assistance of counsel. The Superior Court referred Purnell's motion to a Commissioner for findings and a recommendation. On July 3, 2012, the Commissioner issued her recommendation that the motion be denied, which Purnell appealed, seeking de novo review by a judge of the Superior Court. After hearing oral arguments, the Superior Court issued its ruling denying Purnell's motion on May 31, 2013. Purnell now appeals that decision to this Court.
As we recently stated in Hoskins v. State, " '[w]e review a Superior Court judge's denial of a Rule 61 motion for postconviction relief for abuse of discretion." ' Constitutional questions and other questions of law are reviewed de novo.
Purnell's claims all allege instances of ineffective assistance of counsel in violation of the Sixth Amendment to the United States Constitution. An ineffective assistance of counsel claim requires a defendant to satisfy the two-pronged test set out in Strickland v. Washington. First, the defendant must show that counsel's performance was deficient, " meaning that 'counsel's representation fell below an objective standard of reasonableness." ' " If counsel is shown to be deficient, then the defendant must demonstrate prejudice from counsel's error." 
In analyzing the first prong of Strickland, a defendant bears a heavy burden in demonstrating that trial counsel's representation fell below an objective standard of reasonableness. As we said in Hoskins, " [i]n order to eliminate 'the distorting effects of hindsight,' there is a strong presumption that trial counsel's representation was professionally reasonable." 
" If an attorney makes a strategic choice after thorough investigation of law and facts relevant to plausible options,' that decision is virtually unchallengeable . . . ." 
Strickland's second prong requires the defendant to demonstrate how trial counsel's error resulted in prejudice. We have defined " prejudice" as " a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different."  Mere allegations of ineffectiveness are not sufficient. Instead, a defendant must allege actual prejudice and substantiate it. A " 'failure to state with particularity the nature of the prejudice experienced is fatal to a claim of ineffective assistance of counsel.'"  " In particular, a court need not determine whether counsel's performance was deficient before examining the prejudice suffered by the defendant as a result of the alleged deficiencies." 
A. Trial Counsel's Failure to Request an Accomplice Credibility Instruction
1. The Failure Constituted Deficient Performance Under Strickland's First Prong
Purnell's first claim on appeal is that his trial counsel was deficient for failing to request a jury instruction concerning the credibility of accomplice testimony -- a so-called Bland instruction. In our recent decision in Hoskins II, we trace the somewhat tortured history of the law regarding accomplice credibility instructions. The law as it presently exists requires a trial court to provide a specific Bland instruction any time an accomplice witness testifies. This model instruction, originally set forth in 1970 in Bland, and modified in Brooks, provides:
A portion of the evidence presented by the State is the testimony of admitted participants in the crime with which these defendants are charged. For obvious reasons, the testimony of an alleged accomplice should be examined by you with more care and caution than the testimony of a witness who did not participate in the crime charged. This rule becomes particularly important when there is nothing in the evidence, direct or circumstantial, to corroborate the alleged accomplices' accusation that these defendants participated in the crime. Without such corroboration, you should not find the defendants guilty unless, after careful examination of the alleged accomplices' testimony, you are satisfied beyond a reasonable doubt that it is true and you may safely rely upon it. Of course, if you are so satisfied, you would
be justified in relying upon it, despite the lack of corroboration, and in finding the defendants guilty.
a. The Present State of the Law
In Brooks, this Court issued important guidance as to how cases calling for a Bland instruction should be handled by the trial court. Seeking to " resolve this unnecessarily convoluted area of the law,"  we announced a new rule that requires a trial court to provide a specific Bland instruction any time an accomplice witness testifies -- regardless of whether or not it is requested by trial counsel. This Court unequivocally told trial courts to " give the modified Bland instruction [as stated in Brooks ] or commit plain error."  However, we explained that this new rule would not be retroactive and there would be no plain error where a trial judge provides an instruction that " correctly applied the law as it existed on the day [the trial judge] instructed the jury."  Accordingly, for cases decided before our 2012 decision in Brooks, " our analysis on postconviction review of a Bland claim is governed by the case law controlling at the time of trial." 
Purnell's trial began on April 14, 2008. Thus, we must ascertain the state of the law as of April 14, 2008.
b. The Law at the Time of Purnell's Trial
Following Bland, and up to the start of Purnell's trial on April 14, 2008, we held on multiple occasions that accomplice testimony instructions that departed from the specific wording in Bland were acceptable so long as they were accurate and adequately explained the potential problems with accomplice testimony. For example, in Cabrera v. State, this Court held that a modified Bland instruction was adequate where it " warn[ed] the jurors that accomplice testimony may be suspect because of the accomplice's self-interest and his plea agreement."  Three years later, in Bordley v. State, we held that there was no error where the pattern jury instruction warned that the accomplice testimony " may be affected by self-interest, by an agreement she may have with the State, by her own interest in the outcome, and by prejudice against the defendant."  Four years later, in Soliman v. State, we reiterated that when the jury is provided with a correct statement of the law, even if it does not instruct the jury to examine the testimony " with caution," we will not find error.
c. Cases After Purnell's April 2014 Trial: Smith, Hoskins II, and Brooks
To complete the chronology, in cases after Purnell's trial, we again considered
whether counsel's failure to request a Bland instruction could successfully establish an ineffective assistance of counsel claim. In Smith v. State, a case of first impression, this Court reiterated, " a general credibility instruction is not an acceptable substitute for a specific accomplice credibility instruction."  This Court determined that " the failure of [a defendant's] trial counsel to request a specific instruction on the credibility of accomplice testimony amounted to 'deficient attorney performance' under the first part of [this Court's] Strickland analysis."  However, Smith still required the defendant to establish prejudice under the second prong of Strickland. We explained in Smith that " trial counsel's failure to request [a Bland ] instruction will not always be prejudicial per se."  Rather, " the prejudicial effect depends upon the facts and circumstances of each particular case."  Nonetheless, we found that the defendant in Smith did receive ineffective representation when trial counsel failed to request an accomplice instruction based on the facts of that case.
In Hoskins I, this Court considered whether it was plain error when a judge failed sua sponte to give an accomplice credibility instruction. We held that Smith did not create such a broad rule. We explained that the Smith decision required a trial judge " to give a Bland -type of instruction, upon request, when accomplice testimony is presented."  Thus, it was not plain error for a trial judge to fail to give sua sponte an accomplice credibility instruction.
The progeny of cases after Bland, up to and including Hoskins I, were overruled when we decided Brooks. In Brooks, we held that trial judges must give an accomplice testimony instruction any time an alleged accomplice testifies regardless of whether trial counsel requests it.
But at the time of Purnell's trial, his counsel did not have the benefit of this Court's decision in Brooks. This Court's holding in Brooks is not applicable to our determination of whether the failure to request the Bland instruction was erroneous or prejudicial to Purnell. Instead, the earlier holdings in Cabrera, Bordley, and Soliman provide the applicable framework for analysis.
In Bordley, we stated that " [a]lthough the trial judge in the present case did not instruct the jury to examine [the accomplice's] testimony 'with caution,' the trial judge should be granted wide latitude in framing his jury instruction."  In Purnell's trial, the jury was given a general credibility instruction as follows:
You are the sole judges of credibility of each person who has testified and of the weight to be given to the testimony of each. You are to judge the credibility of
all the witnesses that have testified before you whether for the prosecution or for the defense . . . .
In considering the credibility of witnesses and in considering any conflict in testimony, you should take into consideration each witness' means of knowledge, strength of memory and opportunity for observation, the reasonableness or unreasonableness of the testimony, the consistency or inconsistency of the testimony, the motives influencing the witness, the fact, if it is a fact, that the testimony has been contradicted, the witnesses [ sic ] bias or prejudice or interest in the outcome of the litigation, the ability to have acquired the knowledge of the facts to which the witness testified, the manner and demeanor upon the witness stand, and that apparent truthfulness of the testimony, and all other facts and circumstances shown by the evidence which affect the credibility of the testimony.
The jury was further instructed as follows:
The fact that a witness has been convicted of a felony or a crime involving dishonesty, if such be a fact, may be considered by you for one purpose only, namely, in judging the credibility of that witness. The fact of such a conviction does not necessarily destroy or impair the witness' credibility and it does not raise the suggestion that the witness testified falsely.
The Superior Court found that the instructions were " correct statement[s] of the substance of the law, [were] reasonably informative and not misleading."  However, Cabrera, Bordley and Soliman all contained specific instructions regarding the accomplice's agreement with the State. In Cabrera, the jury instruction " did warn the jurors that accomplice testimony may be suspect because of the accomplice's self-interest and his plea agreement."  In Bordley, the instruction " did, in fact, warn that the testimony of . . . the accomplice may be affected by self-interest, by an agreement she may have with the State, by her own interest in the outcome, and by prejudice against the defendant."  In Soliman, the jury was instructed that it:
may consider all the factors which affect the witness' credibility, including whether the testimony of the accomplice has been affected by self-interest, by an agreement which he may have with the state, by his own interest in the outcome of the litigation, by prejudice against the defendant, or whether or not the testimony has been corroborated by any other evidence in the case.
Thus, in these cases -- where we did not find reversible error in the jury instructions -- language directing the jury to take into account accomplice testimony was used in addition to a general witness credibility instruction. In Purnell's trial, the trial court only gave the general witness credibility instruction. Thus, although a general credibility instruction was given, the jury was not instructed as to the specific concerns regarding accomplice testimony.
What Cabrera, Bordley and Soliman make clear is that Purnell's counsel
was on notice that a separate jury instruction regarding accomplice testimony could be requested. Accordingly, we must determine whether counsel's decision not to request the separate instruction was a strategic one. In Neal v. State, we observed that " [t]hough we do not require lawyers to predict the future, [ Smith and Brooks ] only underscore the concerns that this Court has long recognized: a decision not to request a Bland instruction is not a product of trial strategy."  We further noted in Neal :
even though this Court, at the time of Neal's trial [in August of 2009], displayed some ambivalence about the exact wording of a Bland instruction, " it was well established that, in Delaware, a defendant is entitled, upon request, to a specific jury instruction concerning the credibility of accomplice testimony in cases where the State's evidence includes the testimony of an accomplice." 
In this case, Purnell's trial counsel stated in an affidavit, " [c]andidly, I cannot recall why I did not request the instruction."  Yet, requesting an instruction would have been consistent with trial counsel's strategy. Purnell's counsel wanted to convince the jury that Harris was credible when he initially told police that Purnell was not involved, but then lied at trial as a result of his plea deal with the State. Throughout the trial, Purnell's counsel highlighted Harris' motives in testifying and contrasted these with his motives upon first being questioned by the police. Although this Court only required accomplice testimony instructions to be accurate and adequately explain the potential problems with accomplice testimony and there was no precise language required to be used in the instruction, the instruction
would nevertheless have furthered the defense strategy. An accomplice testimony instruction would have helped illustrate the point defense counsel attempted to make during cross-examination and closing arguments: accomplice testimony must be scrutinized for potential bias and unreliability. We thus conclude that trial counsel's performance in failing to request a Bland instruction " fell below an objective standard of reasonable attorney conduct" and constitutes deficient performance under the first prong of Strickland.
2. The Failure Was Not Prejudicial Under Strickland's Second Prong
Although trial counsel's failure to request a Bland instruction was deficient, Purnell must now demonstrate prejudice under the second prong of Strickland. To show prejudice, Purnell must demonstrate a reasonable probability that, but for counsel's deficient performance, the jury would have decided differently.
Purnell asks us to reexamine the validity of the prejudice standard articulated in Brooks. He claims that Brooks fails to recognize the fundamental differences between the " reasonable probability" inquiry under Strickland and the traditional " harmless error" analysis. He argues that our interpretation of the second prong of Strickland makes it more difficult for a defendant to establish prejudice than what the Supreme Court intended.
The harmless error standard is different from the standard we articulated in Brooks. Harmless error is a burden-shifting test. In Chapman v. California, the United States Supreme Court noted:
Certainly error, constitutional error, in illegally admitting highly prejudicial evidence or comments, casts on someone other than the person prejudiced by it a burden to show that it was harmless. It is for that reason that the original common-law harmless-error rule put the burden on the beneficiary of the error either to prove that there was no injury or to suffer a reversal of his erroneously obtained judgment.
The Supreme Court has further explained that the analytical framework of the harmless error doctrine is " not whether the legally admitted evidence was sufficient . . . but rather, whether the State has proved beyond a reasonable doubt that the error complained of did not contribute to the verdict obtained." 
Our standard in Brooks comports with the standard set forth by Strickland and its progeny. In Strickland, the Supreme Court noted that " actual ineffectiveness claims alleging a deficiency in attorney performance are subject to a general requirement that the defendant affirmatively prove prejudice."  The defendant has
the burden to " show that there is a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different."  Similarly, in Brooks we held that the burden is on the defendant to " demonstrate a reasonable probability that the jury would have decided differently had it heard the Bland instruction." 
Here, we apply the standard for prejudice as it existed at the time of Purnell's trial. Strickland requires us to " consider the totality of the evidence"  in determining whether the defendant has shown that, but for counsel's deficient performance, there is a reasonable probability that the outcome would have been different. " A reasonably probability is a probability sufficient to undermine confidence in the outcome."  It is therefore " not enough for the defendant to show that the errors had some conceivable effect on the outcome of the proceeding." 
The Superior Court considered the totality of the evidence to find that even if Purnell had established deficient performance under the first prong of Strickland, Purnell failed to establish prejudice as required under the second prong. It concluded that there was " significant, additional information before the jury that substantiated the accomplice's testimony."  We agree.
Evidence, aside from Harris' testimony, showed that Purnell was identified as the shooter by three other individuals, none of whom were accomplices -- Hammond, Mitchell and Williams. Hammond testified at trial that he heard Purnell complain that he was " broke" and saw Purnell carrying a semi-automatic gun in his waistband on the day of the shooting. He also testified that Purnell had later bragged that he had " popped" Mrs. Giles because she refused to hand over her money.
Most of Mitchell's testimony came into evidence through a Section 3507 statement because he claimed he could not remember anything on the witness stand. The State introduced evidence that Mitchell was unwilling to cooperate at trial because Purnell had threatened him for being a " snitch." In the statements provided by the police detectives who had previously interviewed him, Mitchell claimed Purnell had confessed to him in April 2006 to killing Mrs. Giles because she recognized him when he tried to rob her. Williams, Mitchell's girlfriend, testified at trial that she overheard a telephone conversation between Purnell and her cousin, Jerome Portis, in which Purnell confessed to killing
Mrs. Giles, although she believed he might have been joking.
The State also introduced the recording of a telephone call between Purnell and Tramont Mitchell, Kellee Mitchell's brother, in which Purnell bragged that he had " a lot" to do with the murder. A video statement from Aqueshia Williams, Etienne Williams' sister, was played for the jury, in which she claimed that Purnell said " I shot one bitch, I'll kill another." 
Moreover, Purnell asserted that he did not associate with Harris, the accomplice, but that claim was undermined by the fact that he was found in Harris' home when Harris was arrested. Purnell also lacked a credible alibi, as he presented two conflicting reports of where he was on the night of the shooting.
Further, as discussed above, the jury was instructed that it had the " sole" responsibility for judging the " credibility of each person who has testified and of the weight to be given to the testimony of each." The jury was instructed to consider the witness' motives, bias, prejudice, interest and general credibility. Additionally, Purnell's counsel cross-examined Harris about his plea, focusing on the inconsistencies between Harris' testimony and his previous statements to the police. He then used his closing argument to reiterate that theme, as to Harris and the other witnesses: " you have been instructed to . . . try to make one harmonious story of the events on January 30th 2006. That is going to be a hard job based upon all those conflicting statements and all the motivation that people have to get out of jail, get out of trouble." 
Strickland requires the defendant to show that there is a reasonable probability that the result would have been different had his attorney not erred. Given the independent evidence corroborating Harris' testimony, Purnell's counsel's vigorous efforts to undermine Harris' credibility at trial, and the jury instruction's general caution regarding " the motives influencing the witness" and the witness's " bias or prejudice or interest in the outcome of the litigation," we do not find that there is a reasonable probability that the jury's verdict would have changed had it heard the Bland instruction. Thus, Purnell has not met his burden to show prejudice as required by the second prong under Strickland.
B. Trial Counsel's Failure to Request a Limiting Instruction Regarding the Guilty Plea of Co-defendant Harris Did Not Constitute Ineffective Assistance of Counsel
Purnell argues that his counsel should have requested the jury be instructed about the effects of Harris' guilty plea based on the fact that they knew Harris was a co-defendant and would learn he had pled guilty. The jurors saw Harris
sitting at the defense table during jury selection, but at the start of trial, Harris was absent. During the State's opening statement, the jury learned that Harris had pled guilty and would testify for the State.
Purnell relies on this Court's decision in Allen v. State  to show that a reasonably competent defense attorney would request a cautionary instruction concerning Harris' guilty plea. The State argues, and the Superior Court found, that the facts in Allen " significantly differ" from the facts in this case. We agree.
In Allen, we considered whether admitting into evidence a certified copy of a co-defendant's guilty plea agreement without live testimony was an abuse of discretion. Allen and two co-defendants were indicted on twenty charges arising from three separate burglary incidents. Both co-defendants entered into plea agreements with the State prior to the trial. One of the co-defendants testified during Allen's trial, but the other did not. The Superior Court allowed into evidence, over defense counsel's objection, the non-testifying co-defendant's plea agreement. We held that " a co-defendant's plea agreement may not be used as substantive evidence of a defendant's guilt, to bolster the testimony of a co-defendant, or to directly or indirectly vouch for the veracity of another co-defendant who pled guilty and then testified against his or her fellow accused."  We did acknowledge, however, that there are limited circumstances in which a prosecutor may seek to introduce a co-defendant's guilty plea. For example, " [d]uring the direct examination of a co-defendant, a prosecutor may elicit testimony regarding that co-defendant's plea agreement and may actually introduce that agreement into evidence." 
The admission of the guilty plea in such a circumstance may serve " the limited purpose of allowing the jury to accurately assess the credibility of the co-defendant witness, to address the jury's possible concern of selective prosecution or to explain how the co-defendant witness has first-hand knowledge of the events about which he or she is testifying."  We made clear that even " [i]n these situations, a trial court must still give a proper cautionary instruction as to the limited use of the plea agreement and the accompanying testimony about it."  We warned that admitting a guilty plea, even for a limited purpose, must be accompanied by a cautionary instruction, because the " absence of such a limiting instruction is an important factor in determining whether the admission of the guilty plea was harmless error." 
The trial court in Allen instructed the jury that there may be " many reasons" why a defendant may plead guilty. However, the trial court never instructed the jury on the proper limited purpose for admitting the actual plea agreement into evidence. This Court reasoned that without an instruction on how the jury
should evaluate the evidence, it left open the possibility that the jury " use[d] the plea agreement as substantive evidence of Allen's guilt, to bolster the testimony of co-defendant Howard or to directly or indirectly vouch for the veracity of co-defendant Howard who pled guilty and testified against Allen at trial." 
In this case, Harris' plea agreement was not offered into evidence. Further, Harris testified and was subject to rigorous cross-examination. Thus, Allen does not provide valid grounds for Purnell to argue that his counsel needed to request a cautionary instruction regarding Harris having pled guilty. Accordingly, Purnell has not demonstrated that his counsel's conduct fell below an objective standard of reasonableness and was deficient under the first prong of Strickland.
C. Trial Counsel's Failure to Appeal the Trial Court's Ruling Denying his Request to Empanel a New Jury Did Not Constitute Ineffective Assistance of Counsel
Purnell argues that his counsel's failure to appeal the trial court's rejection of his request to empanel a new jury was evidence of deficient performance under Strickland. During jury selection, jurors saw Harris at the defense table and understood him to be Purnell's co-defendant. Purnell contends that the jury was likely to infer his guilt based on Harris' guilty plea. Indeed, his trial counsel did request a new jury on April 8, 2008, the day after Harris entered his plea. However, after the trial court denied the request for a new jury, Purnell's counsel did not appeal the ruling. Nor did he include the issue when he appealed the conviction and sentence on other grounds. Purnell's counsel stated in his affidavit that he did not appeal the ruling related to seating a new jury because he " did not believe that this issue would have been successful on direct appeal because the jury swore and [ sic ] oath to be fair and impartial."  He also stated in his affidavit that he " was able to cross-examine Harris concerning the beneficial plea he received to testify in an effort to attack the credibility of his proffer and trial testimony." 
Our analysis of a claim of ineffective assistance of appellate counsel follows the standard Strickland framework. In Neal v. State, we noted that:
Appellate counsel " need not (and should not) raise every nonfrivolous claim, but rather may select from among them in order to maximize the likelihood of success on appeal." Nevertheless, " [i]t is still possible to bring a Strickland claim based on counsel's failure to raise a particular claim, but it is difficult to demonstrate that counsel was incompetent." 
In this case, Purnell has not demonstrated that his counsel was incompetent for failing to raise this claim on appeal. Defense counsel made a strategic decision not to pursue the claim, which is sufficient under the Strickland test. " A strategy, which structures appellate arguments on 'those more likely to prevail, far from being evidence of incompetence, is the hallmark of effective appellate advocacy.'" 
In Jones v. Barnes, the United States Supreme Court held that although a defendant has the final authority to make certain fundamental decisions, such as whether to plead guilty, or to take an appeal, the defendant does not have a constitutional right to compel his counsel to raise issues that counsel, in exercising his own independent and professional strategic judgment, decides not to present. This Court applied Jones in Scott v. State, a case raising a similar issue to the one presented here. In Scott, defendant's counsel stated in his affidavit that he " did not argue [an] issue [on appeal] because [he] did not believe that there was any chance that [this Court] would reverse based on the circumstances of the ruling."  Moreover, Scott's trial counsel did, in fact, cross-examine the witness on the underlying issue that he did not appeal. This Court held that Scott's claim for ineffective assistance of counsel was thus without merit.
In this case, defense counsel stated that his reason for not raising this argument on appeal was because it was unlikely to be successful. Purnell's current counsel does not cite to any rule of law or precedent that says that a new jury must be empanelled whenever a jury is aware that a case has been brought against two criminal defendants, and one of them pleads guilty before trial. Jurors are presumed to follow the instructions given them. The jury swore under oath to be fair and impartial. Counsel used the information concerning Harris' plea as part of the defense strategy. Purnell's counsel sought to do what Scott's counsel did: cross-examine on the issue. Purnell's trial strategy was to show Harris as opportunistic because he was afraid of going to trial and the State offered him a plea agreement. The fact that the jury saw Harris during selection only furthered Purnell's argument. Thus, we find that the trial court did not err in rejecting this claim.
D. Trial Counsel's Failure to Object to Certain Comments by the Prosecutor Did Not Constitute Ineffective Assistance of Counsel
Finally, Purnell argues that his trial counsel was deficient under Strickland for failing to object to the prosecutor's alleged " vouching" for Harris. Purnell alleges that the prosecutor improperly vouched for Harris by asking Harris whether he was " telling the truth" in his statements to police and in his trial testimony, but had lied during earlier statements.
The trial counsel stated in his affidavit that he did not object because he " did not consider the prosecutors [sic] statements to be vouching for the witness because [trial counsel] had raise[d] the truthfulness of his statements during the cross-examination of Harris." 
We reject Purnell's contention that the prosecutor's statements amounted to improper vouching such that his attorney was deficient for failing to object. " Improper vouching occurs when the prosecutor implies some personal superior knowledge, beyond that logically inferred from the evidence at trial, that the witness has testified truthfully."  It is proper for prosecutors to first establish a foundation, which can include a discussion of a witness's truthfulness. Here, the prosecutor asked Harris if he had told the truth in his first two conversations with the police. Then he asked Harris about his plea deal:
Q: Now, Mr. Harris, before you signed this plea agreement, did you go over it with your attorney?
Q: And the agreement states: " The defendant agrees to cooperate with the prosecution of his co-defendant by testifying truthfully during the co-defendant's trial, if called as a witness by either party." Is that correct?
Q: And that was read to you by your attorney?
On appeal, Purnell essentially concedes that the prosecutor's statements did not in fact constitute vouching under current law, but argues that his trial counsel " could have persuasively argued" that our standards for improper vouching " should be re-examined." Here, there is no deficient performance under Strickland because there was no improper vouching by the prosecution, and it is not deficient performance to not object under these circumstances where the prosecutor's conduct comports with existing law. Accordingly, we reject Purnell's claim.
Based upon the forgoing, we conclude that the Superior Court did not abuse its discretion in denying Purnell's motion for postconviction relief. Accordingly, the judgment of the Superior Court is AFFIRMED.
