“It’s probably very similar to 9/11, where you have a lot of work going on searching for survivors, and it’s very mentally heavy on people,” said Jay Settergren of Indiana Task Force 1. “I think it weighs heavy on them.”

On Tuesday, search teams found eight more bodies in the rubble of the condo building, raising the death toll to 36.
