Ryan O'Neal's attorney claims that Griffin O'Neal consumed alcohol just before the now-infamous brawl with his dad, "which could have contributed to his violent outburst."
In a news conference that ended just minutes ago, Ryan's lawyer, Mark Werksman, said that the actor "fired a shot in warning, not in anger" during the fight at Ryan's Malibu home Saturday.
Werksman says Ryan had been out celebrating Farrah Fawcett's 60th birthday, and when he came home, Griffin was there. Ryan asked Griffin to leave and Werksman says that's when Griffin went off.
Werksman says Griffin was the aggressor and Ryan "got the worst of it," adding that Ryan "was thrown to the ground and beaten." Werksman says Griffin beat his dad with a fire poker and Ryan suffered bruises on his arms and legs.
"Ryan will be completely vindicated and exonerated," Werksman added.
