A small-town grandmother who disappeared on her way to work. A beloved director of a Texas summer camp for girls. An Alabama elementary student away from home. These are a few of the dozens of victims lost in devastating flooding in Texas.

Young campers and a dad saving his family were among the dozens killed in the historic flash floods that tore through central Texas over the holiday weekend.

TODAY's Jenna Bush Hager, whose mother, former first lady Laura Bush, was a counselor at Camp Mystic, reacted to the tragic flooding in Texas that left at least 10 children unaccounted for at the summer camp.
