LONG BEACH– Police say a 29-year-old driver has been arrested in connection with a road rage fistfight that escalated into murder.
Long Beach police spokeswoman Nancy Pratt says Duy Tieu of Santa Ana was arrested
shortly before midnight Friday on suspicion of murdering 53-year-old George McCafferty of Long Beach.
Pratt says the two men were fighting on the Carson Street offramp of Interstate 605 when Tieu got back into his car and sped toward McCafferty, who was standing outside his Ford Escort. Tieu allegedly plowed into McCafferty and pinned him against his car, killing him.
Tieu is being held in lieu of $1 million bail.
