Five days after deadly floods struck central Texas, search and rescue teams are continuing to probe debris for those still missing.

The Texas Game Wardens of the state’s Parks and Wildlife Department have searched 26 miles of river since the start of the crisis and have conducted 444 rescues, said Lt. Colonel Ben Baker. The agency has deployed helicopters, drone teams, K-9 units, a variety of boats and four-wheel-drive vehicles to carry out search and rescue missions, he said.

The death toll in Kerr County crept up to 87 on Tuesday as search and rescue teams recovered three more bodies in the flood-ravaged hills of central Texas, according to officials in the county worst hit by the disaster.
