First responders are scouring the riverbanks in hopes of finding survivors. Social media posts are now focused on the faces of the missing.

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.

The search for those swept into deadly floods in central Texas continued Sunday as the death toll climbed. At least 43 people, including 15 children, died in Kerr County, Texas, after the area saw nearly a foot of rain Friday.
