“The patients that we saw were hot to the touch,” Chief Hood said of the victims during the press conference. “They were suffering from exhaustion, no signs of water in the vehicle,” adding that there was no working air conditioning unit.

“We’re not supposed to open up a truck and see stacks of bodies in there,” he continued. “None of us come to work imagining that.”

“This is nothing short of a horrific tragedy,” San Antonio mayor Ron Nirenberg added at the time. “Our job is not to ask why. Our job is to ask how we can help. That’s why you’re seeing medical assistance. As far as the federal investigation goes, that’s in the hands of the feds. I’m sure there will be more questions and hopefully some answers as we move forward.”
