Family and friends of Layla Chrissa Clemons and Jaea Chatman, both 17, packed the courtroom for the arraignment of David Alison Walker, 71.

The 71-year-old man accused of hitting and killing two 17-year-old girls in West Sacramento and then fleeing the scene admitted drinking six to eight ounces of vodka before getting behind the wheel, a Yolo County prosecutor said in court.
