Theresa Marie Lamontagne, 29, disappeared after leaving her mother’s house in Roseville, Michigan, on Monday, September 29, 2003. A New Haven resident and mother of three, she had finished work that day and was wearing medical scrubs and gym shoes when she began calling people for a ride home. Accounts differ about her last moments: one version says a family friend phoned to say they were on the way but Theresa was gone when they arrived; another comes from her brother, who said he heard the front door slam and then saw her get into the passenger side of a white sedan driven by an unfamiliar man. The family has not heard from her since.

Theresa was described as tall, with sandy hair, green eyes, a scar above one eye, and a tattoo on her thigh. Her family says she was under significant stress from work, finances, and a volatile relationship, but insist she would not have abandoned her children; police initially considered a voluntary disappearance after a tip that she might have run off with another man. The case remains an active cold missing person investigation with no definitive evidence about what happened after she left her mother’s home.

Did anyone in the Roseville or New Haven area see a white sedan or a woman matching Theresa’s description around September 29, 2003?
