Laster was last seen in the 6600 block of Harmony Grove Road in Hopkinsville, Kentucky on December 8, 2002. She has never been heard from again. Laster's mother did not report her missing until January 2003, as she has left without warning many times before. She may have traveled to the Nashville, Tennessee area shortly after her disappearance; there was a possible sighting of her at a truck stop there on January 12, 2003.

Authorities believe Laster may have died of a drug overdose after her disappearance. She and her friends had reportedly agreed that if any of them overdosed, the others would hide the body so no one would get in trouble. Her body may be buried or may have been dumped in a well. Laster's case remains unsolved.
