Stefanie D. Welch was 23 when she disappeared from Lakin, Kansas, on February 28, 2001. That morning she followed her routine, dropping her older son at preschool and her youngest at daycare around 9:15 a.m., and was driving her fiancé’s silver 1990 Mazda 626 as she prepared to move out of the mobile home she had shared with her children. She never returned to collect her son and was not seen again.

The Mazda was found abandoned about 11:00 a.m. in a private driveway at a mobile home park in southeast Lakin. Stefanie’s jacket and wallet, which contained $500, were on the front seat. Witnesses reported an unidentified man in black walking away from the car; he is considered the prime suspect but has never been identified. Searches, including checks of many abandoned wells in the area, turned up no trace of Stefanie. Her case was reclassified as a probable homicide in February 2002.

If anyone had contacts, sightings, or information about the unidentified man or the car’s movements that day, can you help fill in what happened to Stefanie Welch?
