Ryan O'Neal's son pleads guilty to drunk driving, weapons charges
O'Neal, 47, had amphetamines, cocaine, marijuana and the anti-anxiety drug Xanax in his system when his car veered into an oncoming lane and collided with another vehicle, prosecutors said. That driver suffered head and back injuries.
O'Neal, who lives in northern San Diego County, was on probation for a drunk driving conviction at the time of the accident, which occurred in the San Pasqual Valley.
A shotgun and ammunition were found in O'Neal's car, leading to a charge of being a felon in possession of a weapon, prosecutors said.
Griffin O'Neal's mother is the late actress Joanna Cook Moore. His sister is Tatum O'Neal.
Sentencing was set for Jan. 12. O'Neal could face a maximum four years in prison.
