NEW HOLSTEIN, Wis. (AP) -- The Calumet County Medical Examiner says an 18-year-old woman found outside a New Holstein home died of exposure to the cold.

But WLUK-TV reports that authorities are still investigating what led to the death of Monica Batts of New Holstein.

Her body was found outside the home Friday by the man who lives there. Investigators say Batts had been there at least six hours before she was discovered. The resident told authorities he did not know her.

Deputies say they don't plan to say much more until toxicology test results come back in a few weeks.

NEW HOLSTEIN, Wis. (AP) -- Calumet County sheriff's officials are investigating the death of an 18-year-old woman found outside a New Holstein home.

They've identified her as Monica Batts of New Holstein.

WLUK-TV reports the man who lives in the home found the body when walking to his garage around 12:30 p.m. Friday. He said he didn't know the victim and is cooperating with the investigation.

Officials say the body was clothed and didn't have any visible signs of trauma. They believe the body was outside for about six hours.

Investigators say they're interviewing friends and family and following several sets of footprints found in the area.

An autopsy is set for Monday to determine the cause of death. The public is not believed to be in any danger.
