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 the emergency dispatcher 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?"
CBS Affiliate WSAW reports that before Saturday's opening statements got underway, a judge denied the defense's motion to allow a faith healer to testify as an expert witness.
Assistant District Attorney Lance Leonard said during his statement that Kara had a chance to live up until the time 911 was finally called, and that on the morning of her death, Kara had a 98% chance of survival had she received medical treatment.
The prosecutor also said that the girl suffered greatly before her death.
Defense attorney Jay Kronenwetter opened his statement by reminding the jury that they haven't yet heard any evidence. He did say that Neuman did take action to save his daughter, by calling family and friends and asking them to pray.
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.
Doctors testified at the first trial that Madeline's gradually declining health would have gotten acute three or four days before she died as her body began shutting down. But despite being unresponsive and in a coma, the girl could have been saved very late into the day of her death with the proper treatment, the doctors said.
Leilani Neumann said during videotaped testimony that the family believes the Bible says healing comes from God and that she never expected her daughter to die. The Neumanns said the girl had not been to a doctor since she was 3.
A criminal complaint said Dale Neumann told police he believed God would heal his daughter right up until she stopped breathing. He also "professed to believe God was going to bring Madeline back to life."
The Neumanns have said the family does not belong to an organized religion.
