Authorities believe a 66-year-old woman who lived alone was the victim of a fatal house fire in Green Lake County.
Sheriff's officials say the homeowner has yet to be found. But the remains have not yet been positively identified.
Firefighters responded to a house engulfed in flames in the Township of Princeton around 4 a.m. Tuesday. While firefighters battled the blaze, crews found a body.
WLUK-TV reports an autopsy conducted Tuesday found that the victim died of fire- and heat-related causes.
Authorities are still investigating the cause of the fire.
