Former major league pitcher Steve Howe had methamphetamine in his system when he was killed after his pickup truck drifted off a desert highway, a coroner's autopsy showed. The coroner's office said Tuesday that Howe, 48, of Valencia died of injuries sustained in the April 28 single-vehicle crash on Interstate 10 in Coachella, about 150 miles east of Los Angeles. Toxicological results determined there was methamphetamine in his bloodstream, the coroner's office said. The amount of the illegal drug wasn't disclosed.
