Lisa Michelle Hatchell, a 37-year-old mother of two and U.S. Army veteran, was last seen on her birthday, July 19, 2003, at about 10:00 p.m. outside the home she shared with her boyfriend near the 5400 block of Warrington Avenue in Philadelphia. Witnesses said she had been in an argument with her boyfriend of 16 years about money just before she disappeared. She had worked at the Philadelphia Navy Yard and had previously lived in Atlanta, Georgia.

Her mother reportedly could not file an official missing-person report with the Philadelphia Police Department until the summer of 2005, delaying a formal investigation and searches of the shared home until two years after Lisa was last seen. The boyfriend voluntarily took a polygraph; results were not released. Several unconfirmed tips have placed Lisa in the Atlanta area over the years. She is described as a Black female, 5 feet 4 inches, about 135 pounds, black hair and eyes; at disappearance her hair was in shoulder-length braids. Distinguishing marks include double-pierced ears, a small scar under her chin, a birthmark on her outer right thigh, very small scars on both ankles, and a previously fractured left ankle. She may also use the names Lisa Cotton or Lisa Henderson.

The circumstances of her disappearance remain unknown and her family believes foul play is possible. If anyone knew Lisa, saw her in Philadelphia in July 2003, or has information about the unconfirmed Atlanta sightings, please come forward.
