Teresa Ann Gruetter was 33 when she was last seen at home in Boring, Oregon, in the late hours of September 11, 1991. She lived on Southeast Hamlet Drive with her sister and her ten-year-old son; her seven-year-old daughter lived with her father. The next morning her bed was unslept in, her car stayed in the driveway and her employer reported she never showed for her secretarial shift in Portland. Her sister reported her missing.

Investigators found no signs of forced entry but Teresa’s purse was gone. Detectives focused on an ex-boyfriend, Bruce Arlen Retchless, who had lived with her briefly in 1990 and whose past included a home break-in where electrical lines were cut and a rope left on a bed, and a 1988 rape accusation that did not result in charges. Retchless has never been charged in Teresa’s disappearance. The case is being treated as a homicide but remains unsolved; suggested links to an unidentified woman found in Wyoming in 1992 have been considered unlikely because of physical discrepancies.

Anyone who knew Teresa, saw her in Boring on or after September 11, 1991, or has information about Bruce Retchless is asked to come forward.
