A Montana man is among those arrested following a fatal officer-involved shooting in Burns, Oregon.

Investigators plan to charge Ryan Waylen Payne, of Anaconda, with a federal felony charge of conspiracy to impede officers from discharging their official duties through the use of force, intimidation or threats, along with group leader Ammon Bundy.

Officials say Lavoy Finicum was killed during the arrest of occupiers in Oregon.

Finicum and several others, including Payne, were detained in a traffic stop Tuesday. Officials said when the two vehicles were stopped, everyone obeyed orders to surrender except for two -- Finicum and Ryan Bundy.

Shots were fired, but it's not known who fired first, officials said.

Ryan Bundy was injured.
