Westmoreland County’s new sheriff said he found an unpleasant surprise on his first day of work: his office was trashed. Sheriff James Albert says boxes filled with old arrest warrants blocked the door to his administrative suite, trash was scattered on floors and desks, and the former sheriff’s dirty uniforms were piled beneath a DVD of the film comedy “Paul Blart: Mall Cop.” Albert, a Democrat, defeated two-term Republican Jonathan Held last fall…but the outgoing sheriff says he didn’t do it. The new sheriff is investigating.
