Summary based on the NamUs case record (MP76013) and 5 other sources
In the early winter of 1991, a 26-year-old mother named Lisa Michelle Davis vanished from Pittsburgh, Pennsylvania. The specific details surrounding her disappearance are limited, with the last point of contact noted as January 1, 1991. At the time she went missing, Lisa was described as a biracial woman of Black and White heritage, standing approximately 5'8' and weighing around 145 pounds. She had black hair, brown eyes, and pierced ears. It is also believed that she may have used the last names Harris or Davis Harris. For decades, her absence was a silent void, not officially recognized by law enforcement until her daughter, a grown woman, took the step to formally report her missing.

The path to officially reporting Lisa as a missing person was a long and painful one for her daughter, Jayqua Harris, who was only three years old when her mother disappeared. Raised by her paternal grandmother, Jayqua's questions about her mother's whereabouts were consistently met with evasiveness. Throughout her life, she was told that her mother had passed away, yet no official death record ever surfaced to confirm this. The absence of any documented activity also failed to provide any indication that Lisa was still alive. Compounding the mystery, Jayqua's father also left Pittsburgh around the same time as Lisa's disappearance, though he later reappeared. Neither he nor Jayqua's grandmother, who has since passed away, ever filed a missing person report for Lisa. It was not until the early 2020s that Jayqua, driven by a lifetime of unanswered questions, contacted the Pittsburgh Police Department to finally open an official investigation into her mother's vanishing.

The investigation into Lisa Michelle Davis's disappearance, handled by the Pittsburgh Police Department, faces significant challenges due to the three-decade gap between when she was last seen and when she was officially reported missing. This passage of time has inevitably led to the loss of potential evidence and the fading of memories. Despite the difficulties, her daughter's persistence has brought a long-overdue focus to her case. The circumstances of her disappearance remain an unsettling mystery, a narrative defined by a daughter's enduring search for answers and the profound silence left by a mother who seemingly vanished without a trace. The lack of any concrete evidence or records of Lisa's existence after 1991 has left her family with a painful and unresolved loss.
