Gunman killed after FBI attack once had top security clearance: report - New York Post

The 42-year-old gunman who tried to attack an FBI field office in Cincinnati Thursday once served in the Navy and Florida National Guard — and held top-secret security clearance for a nuclear submarine.

Ricky Shiffer, 42, who had been under FBI investigation for months, was killed in a shootout not long after he tried to make his way into the Ohio bureau with a nail gun while brandishing an AR-15 style rifle.

Shiffer had been an enlisted sailor aboard the USS Columbia attack submarine, a position that requires top secret clearance, the Wall Street Journal reported late Friday.
