Dennis Danny Mellis was 69 when he was shot during what investigators believe was a robbery at his Upper Darby variety store, Med-Pat Inc. On the morning of January 4, 1993, a passerby found him gravely wounded inside the shop; he was taken to hospital, lapsed into a coma, and died of the gunshot injury on February 1, 1993. Mellis was a Greek immigrant and a well-known local shopkeeper who reportedly carried significant cash; his wallet was found empty at the scene. He was licensed to carry a firearm but was unable to use it during the attack.

Upper Darby detectives pursued leads and revisited the investigation over the years, but no arrests or publicly identified suspects have been announced and the case remains unsolved. Does anyone who knew Mellis or who was in that part of Upper Darby in early January 1993 have information that could help reopen leads?
