A 23-year-old Mountain Lake woman is dead after a rollover accident in Cottonwood County Wednesday night. Hollie Mattison was driving a Chevy Blazer westbound on Highway 60 just outside of Windom at about 8pm when she apparently drifted across the eastbound lane into the ditch, overcorrected to the right and then the left, and the vehicle rolled. Mattison was not wearing a seatbelt, and was ejected from the truck. She was pronounced dead at the Windom Area Hospital. Alcohol was detected in her system.
