Debra Jean Delozier was 20 when she vanished from Tinicum, Pennsylvania, on August 16, 1975. Her disappearance remained unresolved until January 17, 1976, when two rabbit hunters found human remains in Tinicum Marsh about a mile south of Cargo City near the Philadelphia Airport; dental records later confirmed the body was Delozier’s.

Investigators ruled the death a homicide, noting a gunshot wound to the head. Ballistics testing was carried out on the bullet recovered from her skull to compare with evidence from other nearby killings. Police linked her murder to at least three other young women—Mary Ann Lees, Denise Seaman, and Layne Dorothy Spicer—found within a five-mile radius who also had bullet wounds to the head, and authorities noted the disappearance of Elizabeth Lande during the same period. Speculation about involvement by members of the Warlocks motorcycle gang, possibly tied to resistance to sexual assault, was reported but produced no arrests.

Who in the community has information about Debra’s last known movements or the people she associated with in 1975?
