A Douglas County judge Monday sentenced a 33-year-old Lawrence man to serve two years prison for a December incident in which his 5-month-old daughter broke her arm.

District Judge Kay Huff ordered Curtis J. Johnson to serve 27 months in prison. Johnson pleaded no contest to aggravated battery in June. Prosecutors accused of him abusing the girl. She had been taken to a doctor’s office with bone fractures and was later hospitalized.

After Johnson’s December arrest, family members said the girl’s injuries were an accident, but Douglas County prosecutors disagreed.

Huff noted Johnson already has served 76 days in jail, and he is eligible to receive an additional 20 percent off his sentence for good behavior.
