Lila was among more than 20 campers who went missing from Camp Mystic, an all-girls Christian summer camp near the Guadalupe River in Kerr County, following catastrophic flooding on Friday, July 4. Floods in the river caused it to reach its second-highest level ever, according to ABC News.

The first photos from flood-ravaged Camp Mystic, the Christian Texas summer camp from which 27 young girls are missing, tell a heartbreaking story. The images capture both the destruction of the floodwaters—toppled trees and shredded buildings—but also the human traces left behind by the campers.

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.
