According to police, Gregory Charles was driving a black Chevrolet that slammed into a Nissan stopped at a red light at the intersection of Almeda and Reed Road late Tuesday. The Nissan was pushed into the intersection, where it struck a charter bus shuttling for rodeo festivities.
The Nissan then continued through the intersection, where it struck a second charter bus before coming to a stop.
The driver of the Nissan, a 65-year-old man whose identity has not yet been released, was pronounced dead at the scene.
The aftermath of the crash was caught on a witness's cell phone camera as he tried to wake up Charles.

"I was trying to wake him up and pat him for at least like five minutes," witness Chris Gonzalez said. "Pat him hard, trying to wake him up."
Gonzalez also started recording the aftermath of the crash.
"[Charles] woke up and I said, 'Sir can you just turn your radio off?' And he was turning his radio off, trying to turn the radio off and he did turn it off, and I smiled because he is still alive," Gonzalez said.
The video shows that driver was disoriented and did not say anything to witnesses.
His video shows a Chevy pickup truck with extensive front-end damage.
