No one is going to prison, per the article:
“Garfield County authorities declined to file charges, saying there was insufficient evidence the school acted with criminal negligence. The prosecutor said participants knew they were taking a risk.”
also in the article:
“He said he could not go on,” staff member Shawn O’Neal wrote two days later in a statement ordered by the Garfield County Sheriff’s Office. “I felt that he could make it this short distance and told him he could do it as I have seen many students sore, dehydrated and saying ‘can’t’ do something, only to find that they have strength beyond their conceived limits.”
O’Neal didn’t inform Buschow about his emergency water.
“I wanted him to accomplish getting to the water and the cave for rest,” he wrote. “He asked me to go get the water for him. I said I was not going to leave him. ... Shortly thereafter I had a bad feeling and turned to Dave and found no sign of breathing.”
