John E. Demchik was a 13-year-old boy from Inglewood, California, who went missing on June 26, 1971. He was last seen in his neighborhood and searches at the time produced no immediate leads. His remains were found on February 8, 1973, in Imperial County, California, and the investigation determined he had been murdered.

The case was linked to Patrick Kearney, who later confessed to multiple murders and was convicted for a series of killings that included Demchik. Kearney’s confessions and subsequent prosecution were central to resolving what happened to John and to providing legal closure for the family.
