(AP) — A jury has found an Omaha nanny guilty in the death of a 4-month-old baby under her care.

The jury of four men and eight women on Tuesday found Sarah A. Cullen guilty of child abuse resulting in death.

Cullen had been caring for Cash Bell in late February of 2013 when the baby suffered a fractured skull and massive bleeding. Cash died five days later after being removed from life support at a hospital.

The 25-year-old Cullen offered several stories as she tried to explain the baby’s injuries.

Sentencing is set for May. Cullen faces a sentence ranging from 20 years to life in prison.
