Leilani Neumann says sickness is caused by sin and can be cured by praying to God.

That's what she testified at her husband's trial in Marathon County court Tuesday.

Dale Neumann, 47, is charged with second degree reckless homicide in the death of his daughter Kara, 11.

She died of untreated diabetes in March of 2008.

"I began crying out to God and he put it in my heart to start praying. Every day he put it in my heart to every day start asking for divine healing over my family," Leilani Neumann told the jury.

She said that when her family moved to Wisconsin from California, she was filled with the holy spirit to trust in God.

Before her daughter died, she believed ailments and sickness were caused by sin and could be cured with forgiveness and rpayer.

She told the court she was freed of lifelong allergies and anxiety attacks.

Defense attorney Jay Kronenwetter asked her what she attributed that to, and she answered, "I had to humble myself to the Lord."

Dan and Jennifer Peaslee, good friends of the Neumanns, were at their home the day of Kara's death.

They also prayed for the gravely ill girl, but didn't think to call a doctor.

"Because we believed if we prayed for her, she would get better," Dan Peaslee testified.

His wife soldified the defense's stance that the Neumanns truly believed their daughter could be cured by prayer.

"The Neumanns both believe in the power of prayer over medical care, doctors," she said.

Leilani testified that she and her husband had a falling out with the Wormgoors, who had attended bible studies with them.

Randall Wormgoor told the jury he didn't agree with all of Neumann's beliefs, like the Neumann's connection of sin and illness.

"If you have an illness that's an indication of sin in your life," Wormgoor said.

Prosecutors hope to have called all their witnesses by Wednesday.
