The victim, Oscar Hinojosa of Chico, Calif., was killed in the crash, which occurred at 8:30 a.m. Monday on Highway 99 near Yuba City, according to the California Highway Patrol.

After the crash, investigators discovered that the man's laptop was still on and plugged into the cigarette lighter. The screen was cracked, and the laptop was found resting on the right front floorboard, said CHP spokesman Sgt. John Pettigrew.

Hinojosa's 1991 Honda Accord collided with a 2003 Hummer. The occupants of that vehicle, both age 39, were taken to a nearby hospital and treated for minor injuries, he said. The Honda drifted into the oncoming lane, and both vehicles were destroyed in the resulting head-on collision.

"We are still investigating whether he was using the computer or not," Pettigrew said. The couple in the Hummer did not see Hinojosa using the laptop, but investigators will try to find witnesses who might have seen him using it before the crash and will investigate the laptop itself, he added.

Possibly, an application could have been running or even a wireless broadband connection, which would indicate that he might have been using the laptop, if not actually touching it, Pettigrew said. An LED light was on when the laptop was found, which could mean that the computer was being charged or possibly used.
