LINCOLN, Neb. (AP) — Lincoln police say a fire at Wilderness Park Day Camp in Lincoln that broke out on Halloween was arson.

Witnesses told police a homeless person had been spotted in the building before the fire on Tuesday.

The camp supervisor says the building is a total loss.

Andrea Faas says the day camp hosts hundreds of kids every summer.

Fire Inspector Rick Campos says the fire caused about $60,000 in damage to the building and everything inside. He says the park was using the building for storage.
