LOWER BURRELL, Pa. (AP) — A fast-moving fire destroyed the third floor of an apartment building in western Pennsylvania, causing no injuries but displacing more than 25 people. Fire officials said the blaze at the Cedar Crest Apartments in Lower Burrell started in the building’s attic and burned for a while before becoming more intense and gutting the third floor on Thursday afternoon. The building’s first two floors had smoke and water damage. Authorities say the cause of the fire remains under investigation but is not considered suspicious. It wasn’t clear how many residents were home when the fire broke out.
