Records present fuller account of FBI shooting of former Maryland official Roy McGrath

In the end, a cellphone gave Roy McGrath away. The former top aide to Gov. Larry Hogan had eluded federal authorities for three weeks and traveled hundreds of miles. Federal agents were searching for his white Cadillac Escalade across the Southeast. Their break came on the afternoon of Monday, April 3. FBI agents in Baltimore detected a signal from a cellphone that belonged to McGrath in a Costco parking lot outside Knoxville, Tennessee.
