Father and daughter cyclists hit and killed by teenage driver A teenage driver struck a family riding bicycles on the sidewalk in the Northern California city of Concord this weekend, killing a man and one of his daughters, police said. Witnesses told police that the 17-year-old was driving a Cadillac Escalade erratically Saturday morning, passing cars and blazing through an intersection when he crashed into a car changing lanes in front of him. "Then he careened into a family on bicycles on the sidewalk," said Sgt. Matthew Morrissey of the Concord Police Department. Authorities responded shortly after 9:30 a.m. to Treat Boulevard near Oak Grove Road, where they pronounced 41-year-old Concord resident Solaiman Nuri dead, according to a news release from the department.
