COLUMBUS, Neb. (AP) — A trial has been delayed for a 23-year-old Columbus man accused of seriously injuring the 4-month-old daughter of his live-in girlfriend.

Francisco Villatoro has pleaded not guilty to intentional child abuse resulting in injury. His trial was to begin Monday in Platte County District Court.

The trial has been rescheduled to begin Nov. 30. Villatoro’s attorney had sought more time to consult with medical experts about whether shaking had caused the infant’s injury.

Authorities say Villatoro called 911 on May 23 to report that the baby was choking. The infant was taken to Columbus Community Hospital and then transferred to an Omaha hospital. Doctors say the little girl suffered a head injury.
