The driver suffered blunt-force trauma, Medrano said. He died at the scene.
The incident was captured on surveillance video, but the footage was grainy and the fight occurred behind the truck partially out of view, Reynaga said.
“You could see there was a fight going on, but you couldn’t tell who was doing what,” he told the newspaper.
Most of the people involved in the fight were interviewed by detectives and then released, pending the result of an autopsy.
Detectives were waiting for the results of the autopsy to see if the man may have suffered a medical issue during the fight that led to his death, Reynaga said, adding that the crashes “weren’t that impactful.”
The driver was identified only as a man in his 40s.
