In a prosecution for attempted murder, assault, robbery, and possession of an unlicensed firearm, there was sufficient evidence that defendant was the gunman in the robbery as charged, and the evidence was sufficient to support the jury's finding of his guilt on all of the charges. Defendant failed to demonstrate that he received ineffective assistance of counsel, by identifying any act or omission to show that his counsel's performance fell below an objective standard of reasonableness or that counsel's performance prejudiced the defendant resulting in an unreliable or fundamentally unfair outcome in the proceeding. The judgment of the Superior Court entered upon the defendant's convictions is affirmed.
