Cheryl Ann Moser Iacovone was 17 when she left her home on Chipmunk Lane in Secane, Pennsylvania, on July 12, 1977, to walk to a friend’s house and never arrived. She had blonde hair and green eyes and was usually known as Cheryl Ann Moser. She had run away from home before, but on prior occasions she always called to say she was safe; this time there was no contact.

Investigators eventually treated her disappearance as an unsolved non-family abduction after tips linked her disappearance to local motorcycle gangs and suggested her body might have been left in the Tinicum Marsh. That theory gained weight because six other young women, ages 15 to 19, were murdered in the mid-1970s and some were found in the same marsh; several of those victims had known ties to biker groups. Cheryl herself had no known club ties, though she was dating 25-year-old David Thompson, who was convicted in 1978 of conspiracy and assault in the fatal beating of a Warlocks member, and one of her friends had long-standing ties to the Pagans.

No trace of Cheryl has ever been found and the case remains unsolved. If anyone knew Cheryl, where she spent time, or has information about the Tinicum Marsh connections, please come forward.
