Brenda Louise Dunham was 26 and a mother of two when she was last seen in Alton, Missouri, on May 10, 1985. A Thomasville resident, she finished a noon shift at the International Shoe factory in West Plains, visited a friend for a few hours, and then took her usual carpool ride home. She never reported for work the next morning and her final paycheck was never collected.

Those who knew her describe Brenda as sweet, friendly, deeply religious and devoted to her children. Family and friends say she had suffered domestic abuse, and Brenda’s sister, Debi Lawson, and investigators have pointed to the husband’s violent temper as a focal point of concern. A 2012 search of a cistern near Alton turned up clothing and material initially thought to be human bones, and the case was featured on the television show Cold Justice in 2015, but no charges have been filed and the disappearance remains unsolved.

Did anyone in the area know Brenda’s routine, her carpool, or have information about where she might have gone after leaving work on May 10, 1985?
