Williams appealed after a jury convicted him of first-degree murder and related charges. On appeal, he made two primary arguments. First, Williams asserted the trial court erred when it denied his pretrial motion, which challenged the admissibility of the Commonwealth expert’s testimony regarding forensic video analysis. Second, Williams claimed the trial court erred when it denied his request for a cautionary eye witness instruction pursuant to Commonwealth v. Kloiber. The Pennsylvania Superior Court affirmed. The Court held that the Commonwealth expert’s description of the video technology and his use of the technology was proper because the testimony assisted the jury in understanding the evidence. The Court then ruled Williams waived his Kloiber claim. At trial, Williams requested the Kloiber instruction in his proposed jury instructions but did not object when the trial court omitted the instruction in the court’s jury charge.
