Gardner-Tetso was last seen at approximately 3:00 p.m. on March 6, 2005 at her residence in the vicinity of the 7000 block of Bluegrass Road in Rosedale, Maryland. She was planning to meet friends that evening to attend a Motley Crue music concert at the MCI Center in Washington, D. C.; her friends had bought her a concert ticket for her birthday.

Gardner-Tetso never arrived at the concert and has never been heard from again. Her cellular phone has been turned off since her disappearance; the last recorded call was at 3:05 p.m. on March 6. There is a record of her black 1996 Pontiac Trans Am passing through the Baltimore Harbor Tunnel southbound at 7:48 p.m. The vehicle was located on March 17, eleven days later, in the parking lot of a Days Inn in the vicinity of the 6600 block of Richie Highway in Glen Burnie, Maryland. A photograph of the car is posted below this case summary. It has tinted windows and Maryland tags numbered LRN 534.

Authorities are not sure what happened to Gardner-Tetso, but they think she may have met with foul play. Her loved ones say is is uncharacteristic of her to leave without warning. Her husband, who reported her disappearance, has refused to cooperate with the investigation or participate in search efforts, and Gardner-Tetso's family says she was afraid of him and was considering divorce at the time she went missing. He is not being called a suspect in her disappearance, however.

Motley Crue offered a reward for information leading to Gardner-Tetso's safe return, but the offer has yielded no viable tips. She was employed as a dispatcher at Aggregate Industries at the time of her disappearance. Gardner-Tetso is described as a responsible and caring woman who owned a home and cars, had a good job and took good care of her three pets. Her loved ones do not believe she left of her own accord; they believe she was probably murdered. Her case remains unsolved.
