Madeline Kara Neumann of Weston, who had treatable type 1 diabetes, was 5 years old the last time her parents Dale and Leilani took her to a doctor, the Milwaukee Journal Sentinel reported Friday.

"She could have easily been treated and had a long, loving life here on Earth," Everest Metro Police Chief Dan Vergin told the newspaper.

The girl's grandmother, Evalani Gordon, said she tried to convince Leilani Neumann to get the girl treatment, an official document says.

"Leilani Neumann told Evalani Gordon that Madeline would be fine and God would heal her," the document says.

Vergin said the investigation will probably end next week and the Marathon County district attorney will decide whether charges will be filed in the girl's Easter Sunday death.
