Mary Jo Thompson, commonly known as Mary Thompson, was a 33‑year‑old white female last seen on **August 24, 1980**, in **Lufkin, Texas**. At the time of her disappearance, she reportedly had **no permanent residence**, frequently staying with various friends and acquaintances in the Lufkin area.
In terms of physical description, she was approximately **5′0″ to 5′1″ tall** and weighed around **110 pounds**. Her hair was brown—often permed—and her eyes were green.
She had multiple **distinctive scars**: one on her eyebrow, one on the bridge of her nose, another on her upper lip, an appendectomy scar, and a Cesarean‑section scar on her abdomen. She had pierced ears, had undergone surgery for ingrown toenails when young, and typically wore artificial fingernails in 1980.
Records indicate that Mary had a criminal history, including arrests for **selling crystal methamphetamine, marijuana, and cocaine**, which may have contributed to her transient lifestyle. The combination of substance‑related activity and lack of a fixed address made information about her movements in the final weeks before she vanished especially sparse.
Investigatively, both the **Lufkin Police Department** and the **Los Angeles County Sheriff’s Department** were involved. Notably, CASE # 008‑00921‑2699‑400 was assigned by the Los Angeles County Sheriff’s homicide bureau, suggesting cross‑jurisdictional interest possibly due to ties she might have had in California. She was also registered in NamUs as MP9418, although public NamUs entries are minimal, and many case specifics remain withheld or limited.
Despite being missing for over four decades, Mary Thompson’s case remains **unsolved**. No confirmed sightings or credible leads have emerged since August 24, 1980, and investigators have noted that few details are known beyond the basic descriptors and circumstances of her disappearance.
On forums such as Websleuths and Crimewatchers, users have discussed possible connections, unsubmitted tips, and potential unidentified decedent matches. However, none have resulted in confirmed resolution. Websleuths contributors have confirmed that DNA is listed as available in NamUs, yet no matches to any unidentified remains have been made public. One community discussion noted:
> “Mary Jo has an arrest record for selling crystal methamphetamine, marijuana and cocaine… Thompson has never been heard from again. Few details are available in her case.”
