Oregon investigators have concluded that state troopers who shot and killed a key figure of the weekslong occupation of a national wildlife refuge were justified in doing so.

But an FBI team that was also on the scene is under federal investigation for not disclosing they fired two shots that missed Robert "Lavoy" Finicum.

An investigation by Oregon law officials concluded Finicum was going for a gun during the Jan. 26 confrontation with state troopers and FBI agents on a remote road.

But investigators also discovered that FBI agents failed to disclose that they had also fired two shots, neither of which hit Finicum.

The U.S. Justice Department's Office of Inspector General said it is investigating the FBI team's actions, working with Oregon officials.
