BURNEY, Calif. (AP) — A 29-year-old Northern California man has pleaded not guilty to charges in connection with an accidental shooting at his home that left his two young children hospitalized with serious injuries. The Redding Record-Searchlight reports that 29-year-old Kevin Venia entered his plea to felony child abuse and illegally possessing guns and ammunition during his arraignment in Shasta County Superior Court on Wednesday. Authorities say Venia's two-year-old son and his four-year-old daughter remained in serious condition after being hit by a blast from a sawed-off shotgun at the family home in Burney on Monday. Sheriff's officials say Venia wasn't home at the time, but had placed the loaded gun on an ottoman while his three kids played nearby. Detectives believe a third child in the home, a five-year-old boy, was playing with the gun when he accidently shot his younger brother and sister. Venia was being held on $500,000 bail.
