Three young girls dubbed the Fort Worth Trio, go shopping at a local mall but never return home. Mary Rachel Trlica, Lisa Renee Wilson, and Julie Ann Moseley were last seen in the mall. The car the girls were driving, a 1972 Oldsmobile 98, was left behind in the Sears parking lot at the mall, but the girls have not been seen since.
