A California deputy fatally shot a woman in front of her two young children as she charged at another cop with a knife, graphic video shows. The footage, released Wednesday by the Nevada County Sheriff’s Office, shows 33-year-old Ariella Crawford walking along a road in Alta Sierra with her two young children when Deputy Caleb Toderean approaches her. A nearby resident had called 911 on Feb. 4 to report a woman walking in the middle of the road amid “significant traffic,” sheriff’s officials said. The video shows Crawford becoming immediately upset as the deputies approach, prompting her to pull out a large knife. “For reasons yet unknown, Ms. Crawford was very upset with the presence of our deputies despite one of them saying she was not in any trouble,” Nevada County Sheriff Shannan Moon said.
