Katherine Ferruzzo, a Camp Mystic counselor who had been missing since the Texas floods, was found dead on Friday, July 11, Ferruzzo's family confirmed in a statement obtained by NBC 5.

Flash floods surged through in the middle of the night, but many local officials appeared unaware of the unfolding catastrophe, initially leaving people near the river on their own.

Maps show how heavy rainfall and rocky terrain helped create the devastating Texas floods that have killed more than 120 people.
