Source: Friends and family of a bicyclist killed in a crash with an L.A. County Sheriff's patrol car gathered for a candlelight vigil Tuesday evening. They came to remember 45-year-old Alfonso Cerda, a beloved father and brother, and to demand answers about his death. There's a growing memorial with candles, flowers, and a white bicycle at the crash site in the 3500 block of West 107th Street in Inglewood. Cerda's girlfriend, Adriana Ortiz, was on the phone with him when he passed away. She says he called her from a cell phone while pinned under the patrol car. "I have it on my cell phone," she said through tears. "I stayed with him for almost eight minutes, screaming, 'Where are you? Where are you? What happened?'" Cerda was riding his bicycle around 1:30 a.m. Monday when deputies say they thought he pointed a gun at them. They chased after him in their patrol car, and say they accidentally ran over him while trying to pull their car in front of his bike to stop him from fleeing. But family members say they don't buy the deputies' story. "He doesn't do that kind of activity. It just doesn't happen," Christopher Cerda, one of Alfonso Cerda's three children, said. "He's never had a gun, I've never known for him to have guns and it just sounds like they're trying to cover themselves," he added. "Now, it's like, the only time I'll be able to see my dad is when I dream," son Alfonso Cerda Jr. said. "The only time I'll be able to talk to my dad is in my mind." The family is demanding a change in the sheriff's department's practices regarding stopping and chasing people on bicycles. Cerda's brother, Alvaro Cerda, pledged to get justice and the full story behind his brothers' death. "They claim there was a weapon," he said. "But the only weapon found was the sheriff vehicle that rolled over my brother." The Inglewood Police Department, with help from the Sheriff's Department's traffic services detail, is investigating the crash
