BALDWIN, Wis. -- Preliminary autopsy results on the body of a Baldwin woman found in Pine Lake on Sunday morning indicates she was heavily intoxicated when she apparently fell into the water after a car accident and drowned.

The St. Croix County Sheriff's Department said Tuesday in a news release that Kristelle M. Wolle’s blood-alcohol content was 0.216 percent, more than twice the legal threshold for drunken driving.

Subsequent investigation revealed that Wolle, 38, had been out with friends the previous evening and the last contact others had had with her was at 2:19 a.m. at a Baldwin bar.

Deputies learned of the one-vehicle crash about 5 a.m. Sunday. A newspaper carrier saw her vehicle in a ditch and called police.

Reports indicate Wolle’s car hit a power pole near her home’s driveway. Deputies speculate fog may have been a factor.

No one was in the car when deputies arrived. A Department of Natural Resources warden found Wolle's body in the lake.
