An estimate of 20 girls remained missing after deadly flooding caused “destructive” floods at Camp Mystic in Hunt, Texas, Lt. Gov. Dan Patrick said.

The tragic floods have impacted several camps in the Hill Country area, reminding long-time residents of another deadly flood that claimed the lives of teen campers from the Dallas area in July 1987 near Comfort Texas, less than an hour away from Camp Mystic in Hunt.

Families of the missing girls have turned to social media, sharing photos and heartfelt messages in hopes of gathering any information.
