Fire heavily damaged a central Pennsylvania cheese processing plant where about 50 people work.
Plant officials say nobody was inside the Sun-Re Cheese Corp. operation in Sunbury when the fire broke out about 8 a.m. Sunday. The plant is about 50 miles north of Harrisburg.
Witness Jeremy Will lives nearby and says he saw the roof of the plant lift up off its supports and slam back down before he saw a side of the building collapse.
A state police fire marshal was expected to inspect the damage on Tuesday to try to figure out what caused the fire.
Sunbury Fire Chief Ken Kipple says the fire isn't considered suspicious. He says it started in the manufacturing section, which was completely destroyed.
The last workers left about three hours before the fire.
