Tracey Leigh Gardner-Tetso, 32, disappeared from her Rosedale, Maryland home on Bluegrass Road on March 6, 2005. She was last seen at home that afternoon and planned to attend a Mötley Crüe concert in Washington, D.C., that evening with a coworker; she never arrived and all communication stopped. The last activity on her cell phone was a call at 3:05 p.m. that day.

Friends and family described Tracey as responsible and caring, a homeowner who worked as a dispatcher and cared for three pets. They said it was highly uncharacteristic for her to leave without notice and suspected foul play. Investigators quickly focused on her personal life: she had been married about six months to Dennis Joseph Tetso, their relationship was described as troubled, and Tracey had reportedly expressed fear of him while considering divorce. She had also recently begun a relationship with a coworker and planned to attend the concert with that person.

Eleven days after she was last seen, Tracey’s black 1996 Pontiac Trans Am was found abandoned in the Days Inn parking lot in Glen Burnie, Maryland; surveillance showed a man parking the car and walking away. Dennis Tetso’s reported lack of cooperation with investigators and refusal to join searches increased suspicion. Mötley Crüe offered a reward for information but no credible leads were produced.

What did anyone in Rosedale or Glen Burnie see around March 6–17, 2005 that might help trace Tracey’s last movements?
