Wisconsin woman Elizabeth Luebke freezes to death after storming out of house party in -6F temperatures

A 21-year-old woman froze to death after storming out of a house party and into subzero conditions in Wisconsin without a coat and wearing shorts.

The body of Elizabeth Luebke was discovered by a passer-by about 9am Sunday in front of a home in Milwaukee.

Luebke, from Oshkosh, was apparently intoxicated when she left a house party a short distance from where she was found dead, a Milwaukee County Medical Examiners' report said.

Surveillance video from a nearby business shows Luebke collapsing in the snow at about 4.30am.

She was not wearing a coat at the time as temperatures plunged to six degrees below zero, it has been reported.

She is said to have left her friends after an argument on Saturday night and was wearing shorts, stockings and a tank top, according to the New York Daily News. 

The examiners' report says Luebke's mother came to Milwaukee to look for her daughter and came upon the scene while police were investigating.

Kathryn Luebke told investigators her daughter was hospitalized last October with a blood alcohol content of 0.40 after she was found unresponsive at a bar. 

Luebke posted on social media in December that she had stopped drinking and had been sober for a month, the New York Daily News reported.

The death came as the coldest air of the season settled into Wisconsin where a wind chill advisory was in effect for all 72 counties. 

Forecasters expect temperatures to warm toward mid-week with readings in the 20s by the weekend.
