OSWEGO, N.Y. -- A new witness has come forward claiming to have information about Heidi Allen's disappearance in Oswego County 20 years ago.
Gary Thibodeau has spent nearly two decades behind bars for kidnapping Allen, whose body was never found. He's currently in hearing to determine if he should have a new trial.
A Syracuse Media Group report states a man believes he saw Allen's 1994 abduction. Bill Pierce says he was driving past the New Haven convenience store where Allen worked when he saw a man in a white van arguing with a woman outside.
In his statement, Pierce said he saw the man get out, punch the woman in the back of her head, and carry her unconscious into the van with the help of another man.
Pierce claims he didn't come forward until last summer because he assumed investigators caught the right man, but when he saw a picture of James Steen, he said he realized that was the man he'd seen 20 years ago.
Steen is one of three men that has been the focus of Thibodeau's case, with several witnesses claiming he made statements indicating he was involved in Allen's disappearance. Steen denies any knowing involvement.
Thibodeau's hearing will resume February 3. Pierce expects to be called as a witness.
