OMAHA, Neb. (AP) — A man has pleaded not guilty in the kidnapping and stabbing of his ex-girlfriend in Omaha.

23-year-old Dylan Doebelin pleaded not guilty to several charges including kidnapping, attempted first-degree murder and stalking Monday. According to prosecutors, Doebelin kidnapped his ex-girlfriend from her job at a daycare, beat her and stabbed her on July 7.

Authorities say good Samaritans saved the woman when Doebelin stopped his car and the woman jumped out of the vehicle.

Doebelin’s trial has been scheduled for Dec. 15.
