AUBURN, Ind. (WOWO): A fire that forced the closure of an Auburn library was intentionally set.

The Auburn Fire Department, Auburn Police Department, State Fire Marshal’s Office and the ATF have determined that the fire at the Eckhart Public Library on July 2nd was an “intentional act,” according to Fire Chief Michael VanZile.
