Winona middle-schooler charged, after making threats about school shooting

A message about a potential school shooting has led to the arrest of a middle school student in Winona.

The 15-year-old boy could be charged with disorderly conduct and making threats.

Officials at the middle school were told early Thursday morning about a Snapchat message posted by that student.

The message was posted two days before the 20th anniversary of the Columbine school shootings in Colorado.

Late last year, a student at Winona Senior High was arrested for making a comment about committing a shooting at school.
