PICO RIVERA – An adult Latino motorist was shot and killed in the predawn hours Monday at the corner of Slauson Avenue and Rosemead Boulevard, sheriff’s officials said. Shots were heard about 3:10 a.m. in the surrounding neighborhoods. Citizens, gathered in front of Jim’s Charbroiled Burgers in the 7800 block of Rosemead Boulevard, said they heard gun activity. “I heard a real loud bang,” said Helen Lavario, 72, who lives about a block away. “It woke me up, and then about 10 minutes later I heard a helicopter.” Just after 10 a.m., the body was taken away from the scene by the Los Angeles Coroner and a few minutes later the burgundy car, with a broken windshield and broken driver’s side windows, was towed away. An approximate three block radius was closed off to traffic on Slauson and Rosemead and smaller, surrounding neighborhoods until after 12:30 p.m. while detectives conducted their investigation, according to sheriff’s officials. “I’m not surprised by the shooting,” said Lavario, who has lived in the city for 55 years. “But the shootings usually happen on Beverly and Rosemead (boulevards),” she said. Pico Rivera public works and Southern California Edison crews worked to restore power to the traffic signs at the intersection. Businesses in and around the area were closed.
