A 28-year-old mother has been convicted of manslaughter in the 2010 death of her toddler.

A Dawson County jury found Doris Herrin guilty on Friday. Prosecutors had charged her with the more serious offense of child abuse resulting in death, which carries a penalty of up to life in prison.

Police say 3-year-old Misty Herrin was unresponsive when she arrived at a Gothenburg hospital on Dec. 21, 2010. She was flown to a Kearney hospital, where she underwent surgery brain surgery. She died the next day.

Doris Herrin had told doctors the girl fell, but evidence showed she had been hit in the head several times and shaken.

Herrin faces up to 20 years in prison when she’s sentenced Oct. 12.
