Firefighters had to "fight off" at least two Staffordshire Terriers with pickaxes and pipe poles to get to the victims in what he called a "horrific scene."

Firefighters saw a "gentleman being dragged by a dog. They could see him completely bloodied before they got off of the truck," Hood said. 

He said one firefighter was bitten on his leg but is expected to be OK. Another person reported being bitten on the hand. 

"Nobody expects to go out and fight dogs in a situation like they did today," Hood added.

Earlier Friday afternoon, Sims said the dogs had been impounded two years ago for a "mild bite," and neighbors have repeatedly complained about neglect on the owners’ part. 

"Those bites were mild. So those animals finished their state-required quarantine, and the owner played paid reclaim fees, and by state law, we were required to return those animals," Sims said, SBG San Antonio reported.

Local councilwoman Teri Castillo expressed her condolences to the victim's family and thanked emergency responders for their bravery.
