COLUMBUS, Neb. (AP) — A September trial has been scheduled for a 22-year-old Columbus man accused of seriously injuring the 4-month-old daughter of his live-in girlfriend.

Francisco Villatoro has pleaded not guilty. He’s charged with intentional child abuse resulting in injury. His trial is set to begin Sept. 28 in Platte County District Court.

Villatoro was arrested after calling 911 on May 23 to report that the baby was choking. The infant was taken to Columbus Community Hospital and then transferred to Omaha Children’s Hospital & Medical Center in Omaha.

Doctors say the infant suffered a head injury. Police say it happened as Villatoro was caring for the child while his girlfriend was at work.
