Fires were set in three University of Northern Iowa buildings this weekend. It was homecoming weekend on the Cedar Falls campus, and investigators say it appears papers were set on fire in classrooms and offices in the lower floors of Lang Hall, Baker Hall and Gilchrist Hall. Gilchrist is home to the school’s police and top administrators, and among the three buildings, Gilchrist got the most smoke and water damage. Employees who work in that building have been told not to come to work today (Monday) unless their supervisor called them in. The damage in the other two buildings wasn’t as extensive, and classes are on schedule in those buildings today. Authorities were altered to the fires in the university buildings between midnight and 1:15 a.m. Sunday morning. There have been no arrests.
