Smith was employed at a taxi company in Irving, Texas in 2000. She departed from the business after her shift ended at 10:00 p.m. on February 3, 2000. Authorities believe that Smith drove to her trailer home in Weatherford, Texas alone shortly afterwards. Smith's husband was visiting his mother at the time, and their children were not at the residence either.

Neighbors reported that her trailer home was on fire at approximately 4:00 a.m. the following morning. By the time authorities arrived at the residence, it was fully engulfed in flames. Investigators discovered that someone also attempted to set fire to the interior of Smith's vehicle, which was located near her home. She resided alone at the time and authorities were unable to discover evidence suggesting she was a victim of the fire. Smith has never been heard from again.

Investigators believe that an arsonist was responsible for the fire at Smith's residence. An extensive search of the surrounding areas produced no clues as to her whereabouts. Her husband stated Smith is deeply religious and a responsible person who would not have abandoned her children. Foul play is suspected in Smith's case, which remains unsolved.
