The family of Madalyn Zwiefelhofer has filed a suit against the driver convicted of causing a fatal 2018 crash in Lake Hallie.
The civil suit was filed last month in Chippewa County court. It lists as defendants Colten Treu and two insurance companies.
Treu is serving a prison sentence for causing the accident that left four people dead. Zwiefelhofer survived, but her family says she has permanent injuries that are “disabling” and “debilitating,” causing the family emotional distress.
Treu is serving a 54-year prison term for his conviction on four counts of homicide by intoxication.
