Authorities look into cause of motorcycle crash

Los Angeles County coroners will begin investigating whether drugs or alcohol played a role in the fatal motorcycle crash of a 28-year-old Costa Mesan.

Police say David Deane’s 2004 Yamaha motorcycle sped across the double yellow lines on an Angeles Crest Highway curve and slammed head-on into a 2006 Dodge Ram pickup truck just before noon on Tuesday. The crash happened near Mt. Wilson, north of Pasadena. An L.A. Los Angeles County helicopter witnessed the accident from above and quickly touched down on the road nearby the crash to provide medical aid, authorities said. But it was too late and Deane was already dead, California Highway Patrol officials said. The truck’s driver, a 45-year-old man from Santa Paula, was uninjured, police said.
