Theresa Terry Duran was 14 when she vanished from Gorham, Maine after leaving home on Friday, July 27, 1984, saying she would spend the weekend with friends and return Sunday evening. Her parents, Irene and Donald Duran, reported her missing when she did not come back. On September 2, 1984, two people walking in woods off a discontinued section of Plummer Road found decomposed remains later identified as Theresa’s. An autopsy determined she died of three gunshot wounds.

Investigators focused early on a boyfriend and his friend, Mark Parker, after a witness placed Theresa with the two on a dirt bike the day she was last seen. In July 1986 Parker, then 18, and the boyfriend, then 17, were arrested following a statement by an informant and a woman’s claim that Parker had confessed. Parker was acquitted at trial, charges against the boyfriend were dropped, and no one else has been charged. The case remains open with Maine State Police.
