A man armed with a handgun was fatally shot by police in Ontario on Sunday, May 5, after threatening the family of his ex-girlfriend and leading authorities on a pursuit that resulted in a crash, killing one uninvolved motorist and injuring another, police said. Around 10:30 a.m., a 911 caller reported that his sister’s ex-boyfriend was outside their residence in the 400 block of Maple Street threatening to come inside the home unless the sister went outdoors, said Ontario Police Sgt. Joseph Estrada. The man was sitting inside his vehicle when officers arrived and refused to exit. “We learned he has a history of domestic violence involving a gun with the sister, and had a warrant out for his arrest,” Estrada said. Authorities attempted to negotiate with the man for about 30 minutes before he fled in his vehicle, eventually leading onto the 60 Freeway where the man drove against opposing traffic. He then exited the freeway and crashed into oncoming traffic at the intersection of Grove Avenue and Philadelphia Street, injuring motorists in two other vehicles, police said. Police said the man then unsuccessfully attempted to carjack another motorist before fleeing on foot. At least one officer then shot the suspect, who was still armed with the handgun, Estrada said. He was taken to a hospital where he was pronounced dead. The man was not identified by authorities on Sunday. The two victims who were injured in the traffic collision were also taken to a hospital, where one victim died from their injuries. The shooting is being investigated by police alongside the San Bernardino County District Attorney’s Office. Anyone with information should contact the Ontario Police Department at 909-986-6711.
