KERRVILLE, Texas (AP) — Rescuers scoured a devastated central Texas landscape of mangled trees, overturned cars and muck-filled debris Saturday in an increasingly bleak mission to locate survivors, including 27 girls who have not been seen since their camp was slammed with a wall of water in a historic flash flood.

Authorities are still assessing the deadly effects of heavy rains that caused devastating flash floods in Texas Hill Country, leaving at least 32 people dead and many others missing as frantic parents sought word about their daughters unaccounted for at a girls camp near the Guadalupe River.
