Theresa Brown was 22 when she was last seen in Lenexa, Kansas, on June 26, 1989. She was described as a white woman with brown hair and blue eyes, about 5 feet 7 inches tall and roughly 120 pounds. Her disappearance was sudden and uncharacteristic, and she had no known contact after that day.

Details about where she went or what she was doing on June 26 are scarce. Local law enforcement opened an investigation soon after she was reported missing, but few leads developed and the case grew cold. Authorities continue to treat the investigation as active and the family remains hopeful for answers.

If anyone in Lenexa in 1989 remembers seeing Theresa or has information that could help locate her, please come forward to investigators.
