Search efforts continue for a fourth day as a girls' summer camp confirms 27 children and staff are dead, with 10 campers and one counsellor unaccounted for.

At Camp Mystic, a Christian summer camp in Hunt, Texas, where officials are grieving the loss of 27 children and counselors, belongings of the young campers are strewn about the flooded floors of a dormitory, while other items, including a pink backpack and a Camp Mystic t-shirt, were found along the bloated Guadalupe River, photos show.

The death toll from the devastating floods across central Texas surpassed 90 as dozens of people remain missing. In Kerr County, at least 48 adults and 27 children died, according to officials.
