Source: A 16-year-old Arcadia boy who was struck by a car while riding his bicycle over the weekend has died from his injuries, authorities said Wednesday. Roger A. Lewis, who had been on life support following Saturday's collision at Santa Anita Avenue and Duarte Road, died Tuesday at a hospital, Los Angeles County Department of Coroner Assistant Chief of Operations Ed Winter said. The crash took place just before 10 p.m., Arcadia police officials said in a written statement. According to the latest information gathered by the Arcadia Police Department's Major Accident Investigation Team, "The bicyclist was stopped for a red arrow in the southbound ... left turn lane," according to Lt. Tom Le Veque. "The signal for southbound through traffic phased to green and shortly thereafter, the bicyclist swerved to the right, into the path of a vehicle being driven southbound in the number one lane, on the green light," Le Veque said. The 2008 Chrysler Sebring struck the teenage cyclist, who was thrown from his bicycle, police said. Lewis, who was not wearing a helmet, suffered major head injuries. He was pronounced dead at 9:53 a.m. Tuesday, Winter said. An autopsy was pending. Lewis had been riding a Bianchi "fixed-gear" bicycle, police said. The type of bicycle was originally developed for velodrome racing but has grown in popularity among recreational riders in recent years. Lewis was a former student at Arcadia High School, where he studied for a little more than a year before transferring more than a year ago, Arcadia High School Principal Brent Forsee said. The crash remained under investigation, however no crime was initially suspected, police said. Though toxicology results for both Lewis and the 26-year-old Arcadia man who was driving the involved car were pending, driving under the influence of drugs or alcohol did not appear to be a factor, authorities said. "The department sends its condolences to the family and friends of the bicyclist, as well as to the driver and witnesses to the collision," Le Veque said.
