NEW YORK ( CNN ) -- Lisa Michelle Hatchell disappeared on her 37th birthday : July 19 , 2003 . She was last seen at 10 p.m. on the street outside the Southwest Philadelphia , Pennsylvania , rowhome she shared with her boyfriend . Lisa Michelle Hatchell has been missing since her birthday in 2003 . Police have looked for her in Georgia . She and her boyfriend were arguing over money , witnesses told police . Since that night , Hatchell 's family and friends have not heard from the mother of two . Hatchell was a U.S. Army veteran who struggled with drug addiction . But Alonie Watson does n't think her daughter 's drug problem had anything to do with her disappearance . `` She has never disappeared without letting the family know where she is , '' Watson said . `` This is just not like her . I feel in my heart that her disappearance does n't have anything to do with her taking drugs that night and then running away . She just would n't do that . '' She worked at the Philadelphia Navy Yard for a while , got married and then divorced . She had been living with her boyfriend , a construction worker , for a dozen years , Watson said . Her children did not live with them . Her 16-year-old son lived with his father . Her daughter , 7 at the time of Hatchell 's disappearance , lived with Watson . Watson is convinced that her daughter was the victim of foul play . She said Philadelphia police did not officially open an investigation into her daughter 's case until two years after she was reported missing . And so , her boyfriend was not questioned or their home searched until two years after Hatchell disappeared . Capt . John Darby , who heads the Philadelphia police department 's special victims unit , said the `` long-term missing '' unit began looking into Hatchell 's disappearance in fall 2005 . Earlier , the case had been handled by the local precinct . Watch an update on the case . There were two reported sightings of Lisa Hatchell in March 2006 , when tipsters placed her at an apartment complex in Atlanta , Georgia . Philadelphia investigators traveled to Atlanta , but the tips grew cold when an assistant manager at the complex could n't confirm that she had been living there . The trail led back to Atlanta in early 2008 , when another tipster said she might be working as a waitress . Police are also talking to authorities in New Jersey but have developed no solid leads . Darby said the boyfriend , Tyrone Henderson , voluntarily took a polygraph test , but the results have not been made public . Watch how Henderson is still considered a person of interest . Henderson , who has moved from the rowhouse he shared with Hatchell , could not be reached . He has not hired a lawyer , police said . Hatchell is described as an African-American female standing 5 ' 4 '' tall and weighing 135 pounds . She has black hair and black eyes . When she disappeared , she was wearing her hair in a red weave or braids . She has small scars on her ankles from insect bites and a small scar on her neck . She also has double pierced ears and a birthmark on her right thigh .
