The jacket was one of the few things that suggested who he might have been. A gold-plated letter on the right pocket. A small cross on the left. White painter's pants. Black sneakers. Whoever buried him in the woods of a rural South Jersey township in the late 1970s left very little else behind.
The young man, estimated to be somewhere between 16 and 22 years old, was found in a shallow grave in a wooded area of the township in early June 1979. A gunshot wound to the head. Investigators believed he had been killed months earlier, sometime during the winter of 1978 or into early 1979, meaning he had lain unidentified through an entire season before anyone found him.
Partial fingerprints and dental records were recovered at the time, but they led nowhere. Decades passed. The case was eventually closed without resolution, one of those quiet, unacknowledged failures that leave families in permanent limbo and victims without names.
In 2023, state police reopened the investigation and brought in a forensic genetic genealogy unit affiliated with a New Jersey college that had already helped crack other cold-case identifications. DNA from the remains was submitted and run against profiles in public genealogy databases. It took roughly three years, but in April 2026 the match came through.
The young man was Robert Dean Irelan, from Pleasantville, New Jersey. He had been known to spend time in Atlantic City. He had a name, a hometown, and a life, however abbreviated, that investigators are now working to reconstruct. Authorities are asking anyone who knew Robert, or who has any information about his final movements or the circumstances of his death, to come forward.
Nearly half a century on, the question of who killed Robert Dean Irelan remains open. His name, at least, is no longer unknown.
