Case Description

Any updates on this case? Let us know!
Summary based on the NamUs case record (MP7601) and 10 other sources
Tammy Mahoney, a 19-year-old woman, was last seen on May 8, 1981, in Oneida, New York. On the day of her disappearance, she was reportedly hitchhiking along Route 46, intending to visit friends. Witnesses last saw her getting into a vehicle that evening. Tammy never reached her destination, and she has not been heard from since.

It is believed that after Tammy was picked up, she was taken to the nearby Oneida Indian Nation Territory, where she may have been sexually assaulted and murdered. Despite extensive investigations and numerous leads over the years, her body has never been found. Law enforcement has pursued various angles in the case, including interviews with several persons of interest. In 2005, authorities began offering rewards for information that could lead to the recovery of Tammy’s remains or the identification of those responsible for her disappearance. Over time, multiple searches were conducted on and around the Nation’s land, but no conclusive evidence has been uncovered.

Tammy's case remains an active investigation, and the FBI is still seeking information from anyone who may have knowledge about what happened to her. Her disappearance has deeply affected her family, who continue to seek closure. Despite the passage of decades, Tammy's case is considered one of the most notable cold cases in the area.
