More details about two shooting incident and an arrest in Sierra County. Both incidents appear to be random acts of violence, according to the Sheriff’s Department. The department says 40-year-old John Conway of Oroville shot two people, while he was riding a utility terrain vehicle, last Friday afternoon, in the Poker Flat area. Both had non-life-threatening injuries. Then the department received another call from a 15-year-old boy who says he and his father encountered Conway while driving down a dirt road in the same area. The boy says Conway opened fire and killed the boy’s father, Ari Gershman, a doctor from Danville. The boy then fled into the woods and call the sheriff’s department.
