A state police fire marshal has been called in to help investigate the cause of an early morning fire that destroyed multiple trailers in Blair County this morning. 911 officials say the blaze broke out just after 4 a.m. along Chevrolet Drive in East Freedom Township. Fire crews from approximately ten area departments were dispatched to the scene. Authorities say the fire quickly spread through the three trailers before becoming a brush fire. No injuries were reported in the blaze and it is unclear how many individuals were displaced.
