She's been missing since 1974. They've had to live without her and without answers

For over 40 years, a mother and son have been looking for answers to one of Fort Worth's most famous cold cases. On Dec. 23, 1974, Rachel Trlica went shopping at Seminary South Shopping Center with Renee Wilson and Julie Moseley. They never returned and their bodies have never been found. Fran Langston and Rusty Arnold talk about coping with loss and the frequency at which the case is discussed by strangers. (Lena Blietz / lblietz@star-telegram.com)
