Homicide • Lay Opinion Testimony From Crime Scene Investigator • Exclusion of Evidence of Defendant’s Truthfulness

Commonwealth v. Kennedy, PICS Case No. 16-1550 (Pa. Super. Dec. 6, 2016) Olson, J. (23 pages).

Expert opinion was not required for bullet trajectory testimony from the crime scene investigator, where such testimony was rationally based on the investigator’s perceptions of the scene using “trajectory rods,” as the use of such devices would be within the understanding of a layman. Judgment affirmed.
