The body of Hideki Irabu, 42, was found at 4:25 p.m. Wednesday, according to Los Angeles County Sheriff's Sgt. Michael Arriaga.
Irabu lived in Rancho Palos Verdes, but it was not clear whether it was his home.
Irabu was arrested on suspicion of driving under the influence of alcohol in Gardena in May 2010. Police said he was stopped after his car drifted outside of traffic lanes, and he nearly collided with a parked car.
