This December will mark 40 years since Daisy Thurman was found deceased inside her residence in Potosi, Missouri, and investigators still don't have answers. Her home had been burglarized before or around the time of her death, and the case has sat unsolved for four decades.

The anniversary prompted the FBI St. Louis field office to renew its appeal for information, a call amplified this week by FBI Kansas City

on X. According to that post, the Missouri State Highway Patrol has also been asked to help solve Thurman's case. Beyond the fact of her death and the burglary at her home, few details about the decades-old case have been made public.

How to Submit a Tip

Anyone with information is asked to call the Public Toll-Free Automated Tipline at 844-458-6622 or send an email to [email protected], according to KFVS12. The Missouri Attorney General's Office lists the same tipline and email address as the official channel for cold-case information on its website.

A Broader Push on Missouri Cold Cases

Thurman's case surfaces amid a wider effort by Missouri law enforcement to crack open old files. The FBI, the Missouri State Highway Patrol and other state agencies recently announced Missouri's participation in the Cold Case Playing Cards program, the station's report notes. The cards feature a photo and details about an unsolved homicide, missing person, or unidentified remains case, and are distributed inside Missouri Department of Corrections facilities in hopes that someone behind bars might recognize a name or a face and come forward.

More than 25 states have already taken part in the FBI's playing-card initiative, per the same account. As part of the push, the Highway Patrol is also standing up a dedicated cold-case unit, with two full-time investigators assigned to work alongside state and federal law enforcement on unsolved cases statewide.

For now, Daisy Thurman's death remains one of many files investigators hope the new attention — and the approaching 40th anniversary — might finally help solve.
