Five other people, including Mr. Bundy’s brother Ryan Bundy, were arrested, the authorities said.
Were there only seven of them?
"Officials did not say who fired the shots, or if there was an exchange of gunfire. Each of the defendants faces a felony charge of conspiracy to impede federal officers from discharging their official duties through the use of force, intimidation or threats." Peter Santilli and Joseph O’Shaughnessy were also arrested on the same charge in 2 separate incidents, which indicates a coordinated effort.
edit: It was apparently "Blue Tarp Man" Lavoy Finicum that was killed/ Source.
Apparently Bundy and some of his followers were en route to a community meeting in John Day, Ore. about 70 miles away. Local source. Federal law enforcement officers converged on the wildlife refuge after the arrests. There are probably fewer than 30 occupiers inside.
