Police say vandals have damaged Flagstaff schools three times this week.
Authorities are searching for whoever is responsible for breaking into Mount Elden Middle School and Killip Elementary School on Wednesday. Police say vandals smashed glass, trashed classrooms and used fire extinguishers.
A Flagstaff Unified School District assistant superintendent, Bob Kuhn, tells the Arizona Daily Sun that nothing was taken from either school. Killip had to be closed Wednesday because of the damage, while MEMS was not in session.
Killip also was broken into Sunday morning.
A $1,000 reward is being offered for tips that lead to an arrest.
