Mary Rachel Trlica, known by her middle name Rachel, was 17 and from Fort Worth, Texas, when she disappeared after a Christmas shopping trip on December 23, 1974. She was with friends Lisa Renee Wilson, 14, and Julie Ann Moseley, 9. The girls were seen at Seminary South Shopping Center but never returned home.

Their 1972 Oldsmobile was found locked in the mall parking lot with Christmas gifts inside and no sign of the girls. Witnesses gave conflicting accounts: some reported seeing the girls in the mall and a few said they saw men “hustling” them into a truck, but those sightings were never confirmed. The next day Rachel’s family received a letter allegedly from her saying the girls had gone to Houston and would return in a week; the handwriting and the letter’s formal address to her husband Thomas raised doubts about its authenticity.

Despite investigation and recurring leads, the Fort Worth Missing Trio case remains unsolved.
