Dale Neumann's wife, Leilani, was convicted of the same charge this spring in the 2008 death of Madeline Neumann, called Kara by her parents.
The girl died from undiagnosed diabetes on March 23, 2008, surrounded by people praying at the family's rural home in Weston in central Wisconsin. Someone called 911 when she stopped breathing.
Leilani Neumann, 41, faces up to 25 years in prison when sentenced Oct. 6.
Prosecutors contend Dale Neumann, 47, recklessly killed the youngest of his four children by ignoring her deteriorating health. They claim the girl was too weak to speak, eat, drink or walk and that Neumann had a legal duty to take her to a doctor.
Dale Neumann's attorney said Friday, when an eight-man, six-woman jury was picked to hear the case, that he didn't know whether the father would testify in his own defense.
"It would be just a guess right now," attorney Jay Kronenwetter said. "It's the defendant's right. Who knows how the trial goes?"
An Oregon jury on Thursday convicted a father of misdemeanor criminal mistreatment for relying on prayer instead of seeking medical care for his 15-month-old daughter who died of pneumonia and a blood infection in March 2008. The father and mother were acquitted of a more serious manslaughter charge.
In the Wisconsin case, Assistant District Attorney LaMont Jacobson said Neumann's trial likely won't differ much from his wife's.
