A jury has found Leilani Neumann guilty of second-degree reckless homicide in the death of her 11-year-old daughter, Kara.
Neumann showed no emotion as the verdict was read.
She faces a maximum sentence of 25 years in prison.
Authorities say she and her husband, Dale, prayed for the girl instead of getting her medical treatment and she died of complications of untreated diabetes in March, 2008.
The trial started with jury selection on May 15. Opening statements were last Saturday and testimony began Monday.
The defense said it was going to call Neumann to the stand during it's opening statements. But. they didn't call her or anyone to the stand after the state rested.
Prosecutors contend a reasonable parent would have known something was wrong with Kara. They say her mother recklessly killed her by ignoring obvious symptoms, such as she couldn't walk or talk.
Neumann told a detective in a videotaped interview played Wednesday at her trial that the Lord was going to take care of her daughter and all she needed was prayer.
