MANKATO November 13, 2012 (KMKO) – A Madison Lake teen will spend as much 36 months in prison after he was sentenced for firing a gun during a dive-by shooting last March near West High School. 18-year-old Alexander Marxen said prior to sentencing that he “was really sorry for what I did.” After he was sentenced he tried to approach his family and his mother tried to hug him before he was whisked away to jail.
