Jerry Alston, 39, was found dead inside his Schley Street home in Penn Hills, Pennsylvania, on the evening of Thursday, October 19, 2017. Penn Hills police discovered Alston at about 10:24 p.m.; he had two gunshot wounds to the head and was pronounced dead at the scene at 10:41 p.m. The Allegheny County Medical Examiner’s Office ruled the death a homicide and the Allegheny County Police Homicide Unit took charge of the investigation.

Investigators noted no sign of forced entry, a detail that led them to consider that Alston may have known whoever came to the house. Neighbors had complained about a high volume of traffic at the residence, a circumstance detectives said complicated efforts to establish what was happening in Alston’s life. Detectives recovered a McDonald’s receipt at the scene and obtained surveillance footage from the Saltsburg Road restaurant matching the receipt’s date and time.

Police released images from that footage of a person of interest described as an older African American man with a white beard who was driving a light-colored SUV; authorities stressed he was a person of interest, not necessarily a suspect. No arrests had been announced as of late 2017. Anyone who knew Alston or has information about the case is asked to come forward.
