San Bernardino County sheriff's deputies conducting a late-night traffic stop shot and wounded an unarmed passenger in Needles on Monday after another man in the car waved a handgun and shot himself in the head, authorities said.
The back seat passenger with the gun, Jose Daniel Herrera, had told his brother there were warrants out for his arrest and vowed not to return to jail, a sheriff's spokesman said.
He pointed the gun at his head and fired, killing himself, the spokesman said.
Deputies then fired into the vehicle because they thought they were being fired upon, said sheriff's spokesman Chip Patterson.
They wounded Herrera's brother, Ruben Landa, who was in the front seat, he said.
Landa, 28, was flown by helicopter late Monday to a Las Vegas hospital and was expected to survive. Deputies said both brothers were from California.
Landa told sheriff's investigators that shortly before Herrera shot himself he said he did not want to return to jail.
A sheriff's spokesman said deputies were not immediately aware of any warrants for Herrera.
Investigators also said that 30 minutes earlier, Herrera had tried to shoot his former girlfriend in Lake Havasu City, Ariz.
A sheriff's deputy stopped the Toyota Camry just before midnight on westbound Interstate 40 west of Park Moabi Road in Needles. The car had been traveling up to 100 mph and was being driven by a 20-year-old woman, Patterson said. He did not identify her.
