Albert Lea police cited eight Rochester John Marshall students for underage drinking Friday after a local mother reported the teens were drinking at the school’s football game against Albert Lea.

According to police, the mother reportedly parked next to a vehicle at the Hammer Complex that was playing loud music. There were reportedly students waving John Marshall flags around, and a bottle of alcohol in plain view in the car. They were reportedly passing a bottle in the parking lot.

An officer at the game called for backup, and more than 50 teenagers were tested for underage drinking.

The eight cited ranged in age from 16 to 18. The 18-year-old was Madelaine Kathryn Glaeser of Rochester. A ninth teenager was also cited for possession of tobacco.

Police said no one would say where the alcohol came from.

Rochester John Marshall won the game 48-18.
