Former Maryland Governor Larry Hogan's former chief of staff, Roy McGrath, has died after a confrontation with the FBI in Knoxville, Tennessee. McGrath faced charges relating to an alleged scheme to defraud Maryland of over $276,000, and a warrant for his arrest had been issued in March after he failed to appear for his scheduled trial in Baltimore. The exact circumstances surrounding his death remain unclear, although the FBI has confirmed that he was injured during the confrontation and died in hospital later that day. McGrath had pleaded not guilty to all the charges against him, and Attorney Joseph Murtha said in a statement that "Roy never wavered about his innocence." Governor Hogan expressed his sadness at McGrath's death and offered his condolences to his family in a statement. The FBI has launched an investigation into the incident, which it says will be conducted by its Inspection Division.
