The St. Cloud Fire Department and the ATF’s St. Paul Division asked for help from the National Response Team, because of the size of the building and the amount of damage.

The ATF developed the National Response Team to bring its expertise to federal, state and local investigators faced with the challenges of significant explosions and arson fires.

The building was more than 100 years old. The Press Bar dated back to 1942.
