According to ABC 30 (KFSN-TV):

One of what is expected to be several lawsuits has been filed in the major gas explosion at the Fresno County peace officers gun range. Three burned inmates have now joined in this legal action. Their attorney says he filed so fast to make sure no evidence is destroyed.

Wagner says one of the victims is burned on 80 percent of his body.

Wagner has countless questions he wants answered, including who authorized the project and who was overseeing it when the explosion happened.

“The employee who was driving the tractor probably was not given the proper supervision about where to use that backhoe and how to use it and to beware of that pipeline,” said Wagner.

“I think this is going to be well beyond $650,000 — there’s no question about that,” said Capozzi. “For someone to go through a major explosion like that, the emotional damages is going to be tremendous. The pain and suffering that he has gone through, although it may not be as much as others, but it’s going to be a major factor in this case.”
