An 18-year-old identified as Kevin Alvin Jude Carroll was found shot to death in Crum Creek, Ridley Township, Pennsylvania, on December 13, 1978. He had been shot multiple times and his death was ruled a homicide. For decades he was a John Doe; his family in Salem, Oregon, had considered him missing and he was declared legally dead in 2003.

Carroll had been discharged from the U.S. Air Force at McGuire Air Force Base six days before his body was found. He had sent his belongings ahead to family in Oregon and was expected to arrive home for the holidays but never did. A volunteer with the Veteran Doe Network helped generate a lead that prompted a renewed investigation, and fingerprints plus a crime scene photograph led to a positive identification on March 22, 2022.

The homicide remains unsolved and no suspects or arrests have been publicly identified. Anyone with information about Kevin Carroll, his movements after leaving McGuire, or potential witnesses is asked to come forward.
