A judge has dismissed all charges against three western Pennsylvania emergency management supervisors who had been accused of obstructing an investigation into an emergency dispatcher accused of failing to send an ambulance to the rural home of a woman who died of internal bleeding about a day later. Senior Judge Katherine Emery wrote in dismissing the cases last week that there was “not a scintilla of evidence” that Gregory Leathers, Robert “Jeff” Rhodes and Richard Policz acted maliciously or blocked investigators from accessing information within the Greene County 911 call center, The (Washington) Observer-Reporter reported. The three were charged last year with tampering with public records, tampering with or fabricating evidence and obstruction.
