PORTLAND, Ore. (AP) — FBI agents involved in the traffic stop that led to the killing of one of the armed occupiers of an Oregon wildlife refuge are under investigation for not disclosing they fired shots that missed Robert "LaVoy" Finicum, authorities said Tuesday.Oregon State Police fired the three rounds that killed the Arizona rancher during a confrontation with authorities on a remote road, Oregon law enforcement officials said at a news conference in Bend.But the results of an independent investigation by Oregon authorities found the troopers were justified in shooting Finicum because he failed to heed their commands and repeatedly reached for his weapon, Malheur County District Attorney Dan Norris said.The investigators discovered members of an FBI hostage rescue team who were at the scene failed to disclose they fired two rounds.As they looked into how many shots were fired during the confrontation and by whom, the investigators found a round in the roof of Finicum's truck."We could not explain the fourth shot into the roof of the truck, or its trajectory given the placement of the Oregon State Police troopers at the time," Deschutes County Sheriff Shane Nelson said.
