“This arson was an attack on a public institution that displaced hundreds of students and educators for the remainder of the school year. Destruction of public property by arson is a particularly cowardly violent crime and I will make sure that all of ATF’s resources are made available throughout this investigation,” ATF St. Paul Field Division Special Agent in Charge Scott D. Sweetow said.

On Tuesday morning, crews were called to the school on a report of a fire. When authorities arrived, flames were shooting up in the air out of the roof of the school. The fire likely started in the front of the school near administrative offices and the school’s library.
