McLemore lived with her mother and grandmother in Kent, Washington at the time of her disappearance. Her grandmother spoke to her on the phone at 6:30 p.m. on April 9, 2009. McLemore's mother was dying of scleroderma, a serious autoimmune disease, and on April 9 her grandmother told McLemore that her mother's condition was worsening. McLemore assured her grandmother that she would come home. A witness reported seeing her in Kent that day, near 30th Avenue South and Kent-Des Moines Road. The witness saw a green 1990s model pickup truck, possibly with Oregon license plates, approach McLemore. She has never been heard from again. Her mother died three days later, but her family was unable to get in touch with her. The day after her mother's death, McLemore's cellular phone went out of service and stopped taking messages.

Authorities discovered McLemore's cellular phoned dialed 911 at 9:15 p.m. on April 10, the day after she was last heard from. The dispatcher heard a woman asking for help, but the phone did not have a GPS sensor and its exact location could not be determined before the line went dead. Authorities believe the call came from the Kent area, however. The caller has never been identified.

McLemore has a young daughter whom she left in the care of her boyfriend, the child's father. Her boyfriend describes her as a devoted parent who would not have abandoned the child. She was unemployed at the time of her disappearance, and very close to her mother. McLemore enjoys dancing and roller skating. Due to the circumstances of her disappearance, she is considered to be in danger. Her case remains unsolved.
