A West Virginia man accused of fatally shooting three co-workers at a western Maryland machine shop remained under police guard at a hospital Friday, but authorities said a Maryland state trooper injured in a shootout with the suspect was treated and released.  The 25-year veteran of the Maryland State Police was shot when police said the fleeing suspect fired multiple rounds at troopers who tracked him down in western Maryland. At least one trooper returned fire, striking the suspect, state police said. The injured trooper and suspect were both taken to a hospital. The trooper has been released, but the suspect remained under police guard while undergoing treatment, police said late Thursday. Charges are pending consultation with the Washington County State’s Attorney’s Office, police said. The troopers involved in the shooting will be placed on administrative duty while an investigation is conducted. Washington County Sheriff Doug Mullendore said three men were found dead at Columbia Machine Inc. in Smithsburg on Thursday afternoon and a fourth was critically injured. The victims and suspect were all employees at the facility, he said. The sheriff identified those killed in the shooting as Mark Alan Frey, 50; Charles Edward Minnick Jr., 31; and Joshua Robert Wallace, 30.
