As first responders continue to rescue people stranded by the torrential flooding that descended on central Texas Friday, dozens of people are facing a parent’s worst nightmare: Their children are missing.

At least 67 people are dead following flooding that slammed central Texas over the weekend, while a desperate search for 11 missing girls continues.

Authorities said at least 24 people have died in flooding around Kerr County, Texas, and officials are still performing water rescues.
