***UPDATE: Austin Cottrell has been found dead. Deputies do not believe his death to be suspicious.***
The Winnebago County Sheriff's Office is searching for a 24-year-old man who has been missing since Saturday night.
Austin Cottrell was last seen near Stonewood Court in the Town of Black Wolf. He is believed to be on foot and was wearing a Milwaukee Bucks pullover with a t-shirt underneath, dark jeans, dark colored shoes and glasses.
It is possible Cottrell was feeling the effects of hypothermia and became disoriented when he went missing. For that reason, deputies are requesting that the public check their properties for anywhere a person could enter to escape from extreme elements. If Cottrell did seek shelter somewhere, he would be in need of medical attention at this point, according to the Winnebago County Sheriff's Office.
Sheriff's deputies believe Cottrell could be anywhere in the southeastern portions of Winnebago County, or even northern Fond du Lac County.
The sheriff's office searched day and night on Sunday, utilizing deputies, a K9, multiple fire departments with personnel and ATVs, night vision, Wisconsin Emergency Management's drone unit, ThedaStar helicopter and a Coast Guard helicopter.
Anyone who sees anything suspicious is asked to call 911.
