Arnold Schwarzenegger has been arrested for investigation of driving under the influence after a gruesome crash that killed three adults and a toddler. Robert Vellanoweth, 63, of Sacramento, was arrested on suspicion of gross vehicular manslaughter and felony driving under the influence of drugs or alcohol, police said. Vellanoweth is a former activist with the Republican National Hispanic Assembly who also was listed as vice chairman of Latinos for Arnold-Northern California during the 2003 recall election. Schwarzenegger appointed him last November to the state Board of Optometry. The Governor’s Office said Tuesday that he would be removed immediately from that post. Police say Vellanoweth was driving a 2005 Jeep Cherokee that slammed into a 1984 Chrysler LeBaron carrying five people Monday afternoon. Brittanya Metchelle Nash, 17, her sister, Brizchelle Ta’Corra Rice, 21, and Rice’s 19-month-old daughter, Kamall Dino Savant Osby, died in the crash, the Sacramento County Coroner’s Office said Tuesday. Also killed was Shanice Patrice Carter, 18. A fifth occupant of the car, a 16-year-old girl, was taken to a local hospital with critical injuries. The Jeep Cherokee crossed into oncoming traffic and hit the Chrysler head-on during a rainstorm about 4 p.m. Monday, police Sgt. Matt Young said.
