The woman behind the wheel of an SUV that crashed into the Mississippi River in Winona last month, killing herself and three passengers, was drunk. 

Winona County Sheriff Dave Brand told the Winona Daily News on Tuesday that Christina Hauser, 36, had twice the legal limit, according to toxicology reports.

Her blood-alcohol level was .16. Three men who were friends since childhood in Lanesboro, Minn. -- Andrew Kingsbury, Matthew Erickson and Blake Overland -- met Hauser in a downtown bar that night and were in the vehicle when it crashed.
