“His face was puffed out a lot because of the injury,” said Joseph Lopez, an employee at the Arco gas station.

Lopez was done with his shift and taking a coworker home when he saw everything.

“I turned around and said ‘We can’t leave him like that because the guy could be dead we don’t know what’s the matter with this guy. We need to help him, call an ambulance,’” he said.

“What could you do? If it was that fast..what could you do?” said Mike Sanders, a gas station customer.

Modesto Police said these suspects have likely done this before. Just days before this attack, police responded to Maze Boulevard and Martin Luther King for an assault and robbery. The suspects were armed with handguns and stole cash, leaving one victim hurt so bad they went to the hospital.

Police ended up catching and arresting four males for the crime. Two of them teenagers and the oldest just 25.

“Kids…you’d hope you could defend yourself from them, but when there’s a bunch of them that don’t care and have the blood lust for whatever they want..they’re going get it,” Sanders said.

Lopez said he’s used to violent crime on the job and calls it part of his routine.

“Just another day in Modesto..sorry to say but that’s how it’s getting around here,” he said.
