Carol De Arment, 36, vanished from Troy, Michigan, after leaving a boyfriend’s apartment sometime between 11:00 and 11:45 p.m. on October 26, 1983. She intended to return to the Wentworth Place home she shared with her estranged husband, Donald DeArment, but never arrived. Her 1981 Buick was later found in the driveway with the keys in the ignition and her purse and eyeglasses on the front seat; her clothing, money and other personal belongings remained in the house.

The couple were amid a bitter divorce, and Carol had alleged physical and sexual abuse in court documents, saying she feared for her safety. Friends described Donald as controlling and said Carol would never voluntarily abandon her three children or leave without telling them. Investigators found blood matching Carol’s blood type on a sofa in the house and in the trunk of Donald’s 1978 Mercedes; Donald said he had not seen her since October 19. Donald died of cancer in 1986 and Carol was declared legally dead in 1993. The case remains unsolved.

Does anyone who lived in Troy at the time or who knew the family have information about Carol’s movements that night or about the condition of the house and vehicles then?
