Lisa Michelle Davis was 26 when she vanished from Pittsburgh in early winter 1991, with the last known contact on January 1, 1991. Described as biracial, Black and White, she was about 5 feet 8 inches and 145 pounds, with black hair, brown eyes and pierced ears. She may have used the last names Harris or Davis Harris.

Her disappearance was not reported to police for decades. Her daughter, Jayqua Harris, who was three when Lisa went missing and was raised by her paternal grandmother, eventually opened an official missing-persons inquiry with the Pittsburgh Police Department in the early 2020s. Family members reportedly told Jayqua her mother had died, but no death record or any documented activity for Lisa after 1991 has been found.

The long gap before an official report has complicated the investigation: potential evidence and memories from the time have faded. Does anyone who lived in Pittsburgh around 1991 remember Lisa, the names Harris or Davis Harris, or have information that could help her daughter’s search?
