Monica Carrasco was 16 when she vanished from her aunt and uncle’s rural Balmorhea, Texas, home. She was staying there after a disagreement with her mother and was last seen asleep around 1:30 a.m. on October 2, 2003; by morning she was gone. Only her beige nightgown and her Bible were missing; her shoes and socks were left behind.

The terrain around the home is rugged, with rocks and thorny plants that would make travelling barefoot difficult. Investigators considered several possibilities, including that Monica left to meet someone she had met online or became disoriented because of her medication, but nothing has been confirmed. A bus driver who had previously harassed her was interviewed and ruled out; reports say Monica’s uncle failed a polygraph. She was a religious junior in high school who had battled depression and anorexia after her father’s death. Texas Crime Stoppers is offering a reward for information.

If anyone knew Monica, her habits, or movements in late September 2003, can you share what you remember?
