Hall was last seen in Flint, Michigan on September 22, 1998, the day after her fourteenth birthday. She left her grandmother's apartment to go to another apartment upstairs and return a book. She never returned.

Earlier on the same day Hall disappeared, an older friend, Melissa Pierce, took her to the state Department of Human Services to report she was being abused or neglected. Late that night, Hall called Pierce from a pay phone at Ann Arbor and West Court streets near the White Horse Tavern. Hall said she was having trouble at home and needed to leave Flint. She asked Pierce if she could go and live with her. Pierce was in another part of the state at the time. She got a ride to Flint with her uncle, but by the time they arrived Hall had vanished. Pierce and her uncle drove around looking for Hall, but could not find her. She has never been heard from again.

Hall was raised by her grandmother, as her mother was found to be an unfit parent. Her mother, who maintained sporadic contact with her, died of a drug overdose in 1996. Her father's identity is known. Hall grew up in poverty; she and her grandmother changed residences frequently and often relied on public assistance, such as food stamps, to meet their needs. Prior to her disappearance, she had been getting into trouble for being truant from school, rebelling against her grandmother's rules and associating with drug users. Hall's loved ones describe her as an intelligent but angry, withdrawn teenager. She had missed so much school that foster care placement was being considered.

Authorities believe Hall probably left of her own accord to escape the troubles in her life, but Pierce says Hall would have contacted her if she could have and believes Hall was probably the victim of a predator. None of her relatives have heard from her since 1998. She may have traveled to the Los Angeles, California area with an adult male boyfriend after her disappearance. Hall was a student at McKinley Middle School in 1998. Her case remains unsolved.
