WAUSAU, Wis. (AP) -- Police say the investigation into the death of an 11-year-old rural Weston girl from untreated diabetes should be completed Friday.

According to police, the girl's parents had chosen to pray for her to get better instead of getting her medical help.

Madeline Neumann died last Sunday afternoon after a relative in California alerted Marathon County that the girl may have gone into a coma.

Friends at the girl's home then made a 911 call, telling a dispatcher the girl wasn't breathing.

Everest Metro Police Chief Dan Vergin says he expects to complete the investigation by tomorrow and forward the results to the district attorney for review.

Former Supreme Court Justice Janine Geske says a possible criminal charge in the case could be second-degree reckless homicide, which requires proof of "recklessly causing the death of another human being."

But she also says Wisconsin law says a parent cannot be accused of abuse or neglect of a child if in good faith they selected prayer as a basis of treatment for a disease.
