WEST WHITTIER – After being hit by a shotgun blast while sitting at a bus stop Wednesday morning, a 16-year-old boy got onto the bus and rode to school, police and school officials said. Wednesday afternoon, police arrested a suspect in the shooting, a 17-year-old boy described by sheriff’s officials as a known gang member. The shooting occurred about 7:30 a.m. at the bus stop at Norwalk Boulevard and Mines Avenue. That’s where the victim was waiting for his ride to school when the gunman approached, Sheriff’s Department officials said. “He rolled up on a bicycle with a shotgun,” said Sgt. Eric Giambalvo of the sheriff’s Operation Safe Streets anti-gang unit. “He shot him and took off.” The 16-year-old was hit in the back with shotgun pellets. County Fire Department rescuers airlifted him to Los Angeles County-USC Medical Center, where he was in stable condition Wednesday, authorities said. At the shooting scene, several residents said they heard a gunshot and screaming. One neighbor called Frontier High School and reported that a boy had been shot, had boarded the bus and was on his way to the school, officials said. The boy, whom police did not identify because he is a minor, got off the bus at Frontier High and was met by security guards. “He made no report to the bus driver,” said Frontier High School Principal Gabe Moorman. Officials asked the teen if he was OK and he did not respond. They said the teen was reluctant to talk about the shooting. Sheriff’s Pico Rivera Station Sgt. Della Walls said deputies received a call that shots had been fired at the bus stop. “We responded there, and there was nothing,” she said. Witnesses told sheriff’s officials that the shooter wore a green sweat shirt and black pants. Two gang detectives later spotted a teen who matched the description of the suspect walking around in the area, Giambalvo said. They searched his unincorporated West Whittier home and recovered a shotgun, he said. Giambalvo said the suspected shooter is a known gang member. But he did not say what the motive may have been for the shooting. Detectives interviewed the suspect Wednesday afternoon at the Pico Rivera Station. Investigators expect to file charges against him Friday. They hope to charge him as an adult, Giambalvo said.
