A man is dead after being shot by a deputy in Sacramento County on Saturday, according to the sheriff's office. The sheriff's office said the shooting happened on the 6500 block of Campanile Street in Rio Linda around 8:30 a.m. The sheriff's office said deputies responded to the neighborhood, located near Rio Linda and Elkhorn boulevards, around 8:15 a.m. after a family member called about a person who was suicidal. "From there, they contacted the subject who was reported by family members as having cut himself and having been in a bathroom," said Sgt. Amar Gandhi, a Sacramento County Sheriff's Office spokesperson. Gandhi said the family had left the residence by the time deputies arrived. The man was inside the garage, and deputies nearby tried to negotiate with him to come out. According to the sheriff's office, the man eventually did leave the garage, but he was holding a knife and began walking toward deputies. KCRA 3 asked Gandhi if the man was charging at the deputies or had intent to harm them.''I can't say exactly whether he was charging, but he was advancing toward the deputy and was within several feet in a pretty close proximity before he was shot," Gandhi said. The sheriff's office said less lethal shotgun rounds were used but were not effective. Gandhi said one deputy opened fire, shooting the man several times. The man was pronounced dead at the scene.KCRA 3's Orko Manna spoke with family members at the scene, who identified the man shot and killed as Christopher Gilmore.His sister Bobbie Gilmore said Christopher's housemates called the family in the morning and said he was trying to harm himself. Bobbie said she called 911 in the hopes that law enforcement could assist him."He needed help. It was a cry for help, and I warned the police before they even went in there that this was a cry for help. He needed help. He didn't need to be shot. He didn't need to be murdered. He needed help. And if anything, he would never hurt nobody else. That's not my brother. He doesn't hurt people. He wouldn't hurt nobody. He was just hurting himself, and they shot him, they murdered him," Bobbie said. "He didn't deserve this. He was a good guy. He had a good heart."Bobbie said she and other family members were just across the street when the shooting happened."I watched my brother take his last breath. Something I will never, ever forget," Bobbie said.The family said even though the less lethal shotgun rounds did not prove to be effective, the sheriff's office should have used another non-lethal tactic."They could have tased him. They didn't try tasing him or anything," Bobbie said. "They didn't handle it right. They didn't handle it right at all."KCRA 3 asked the sheriff's office about why other non-lethal resources were not deployed. Gandhi said after the less lethal shotgun rounds did not work, the man kept walking toward deputies while still holding the knife, and there was not enough time given the potential risk to deputies."You're talking within split-second decisions," Gandhi said. "We try every mitigating factor we can before having to go to lethal force."No deputies were injured, the sheriff's office said.Homicide detectives stayed at the scene for hours investigating the shooting. The sheriff's office also said the Sacramento County District Attorney's Office is completing a concurrent investigation.Gandhi said the deputy who fired his weapon was placed on administrative leave, as is protocol in shootings involving sheriff's deputies. A sheriff's office video detailing the circumstances of the shooting, including body camera footage, will be released at a later date. This is a developing story. Stay with KCRA 3 for the latest.
