Details of Disappearance

Tammy Mahoney was last seen by family or friends on May 08, 1981 in Oneida, New York - USA.

Tammy Mahoney (then 19), was last seen on 05/08/1981, hitch-hiking on Route 46 in Oneida, Madison County, New York, near the Oneida Indian Nation Territory. 

Open source information reports, Tammy did not possess a valid drivers license nor did she own / operate any known motor vehicle. It's believed Tammy was picked up while hitchhiking in the City of Oneida, Madison County, NY and taken to a party on the Oneida Indian Territory, Route #46 in the City of Oneida.

Subsequent investigation over time (including a 1996 multi-agency police effort) has resulted in possible identification of suspect/s and witnesses and much intelligence. Very little cooperation was generated as a result, however case information continues to be received.

Currently, she would've been 59 years old, but has not been seen nor her body found since the time of her disappearance.

If you have any information on the whereabouts of Tammy Mahoney, you are encouraged to contact the Oneida Police Department at (315) 363-9111, ask for William Clark, Investigator. Be sure to have the case number 81-1985 available as you will need it.
