Justin Allen Wiley, 22, was shot to death in the early morning hours of July 2, 2015, in Erie, Pennsylvania. At about 12:20 a.m. police responding to a 911 call found Wiley unresponsive in the driver’s seat of his silver Grand Am, which had come to rest in the yard of a corner house near 19th and Chestnut Streets. He had sustained a single gunshot wound to the back of his head.

The investigation identified Dawaun Dupree Carson as a suspect. Evidence at trial described an ongoing dispute between Carson and Wiley: witnesses said Wiley had thrown a bottle at Carson’s Jaguar outside a local bar shortly before the killing, and Wiley had reported to police on May 31, 2015 that Carson had fired shots at him near another bar. Testimony also described Carson as a heroin dealer, and prosecutors introduced an alleged jailhouse letter from Carson seeking an alibi for the time of the shooting.

A jury convicted Carson of first-degree murder. On December 7, 2016 he was sentenced to life without parole, plus an aggregate 24 to 48 years for related charges; his subsequent appeal was denied. Does anyone have information about Wiley’s last hours or the dispute that preceded his death?
