MEMORANDUM OPINION 
John A. Parkins, Jr. Superior Court Judge
The State has moved to exclude expert psychiatric testimony of Susan E. Rushing, M.D. on several grounds, including the testimony is unreliable and that she is not qualified to render some of her opinions. The court need not reach these issues because, under the circumstances of this case, it finds that Dr. Rushing's testimony would not be helpful to the trier of fact.
The State has advised the court that it will offer evidence that on Christmas Eve 2012 the defendant was visiting the home of his sister, the victim, Myron Ashley and their child, Myron Ashley, Jr. During defendant's visit the sister and her six-year-old son went upstairs, leaving defendant and the victim alone downstairs. Suddenly there was the sound of gunshots. The sister and her child ran downstairs and found the victim on the floor bleeding from the chest. When they got downstairs the six year old saw the defendant hide a weapon in the sofa and later told the police about what he had seen. When the sister tried to talk to the defendant he punched her in the face and fled out the door. The shooting victim was rushed to the Christiana Hospital where he was pronounced dead. The defendant was arrested the next day at his grandmother's house. Gunshot residue was found on defendant's hands.
