BURNS -- As state troopers trained their guns on Robert "LaVoy" Finicum along a secluded eastern Oregon highway, he reached twice for a pocket that police say contained a 9 mm semi-automatic handgun.

That's when they fatally shot Finicum, a video released Thursday by the FBI appears to show.

The federal agency played the video in an attempt to dispel rumors about the circumstances of Finicum's death two days earlier as he and other leaders of the armed standoff at the Malheur National Wildlife Refuge were driving to a meeting.

Conflicting accounts of his shooting fueled outrage among supporters of the refuge occupiers and prompted the leader of a Northwest militia group to issue a call for members to report to Burns.

Greg Bretzing, a special agent with the FBI, said the footage provides an "honest and unfiltered view" of what happened.

The grainy video, taken from an FBI plane flying above the traffic stop where Finicum died Tuesday, depicts a dramatic scene that lasted several minutes and included a short high-speed chase.

It began as Oregon State Police officers and FBI agents stopped a Jeep and a white pickup as they traveled north on U.S. 395 toward John Day.

Finicum, an Arizona foster parent and rancher who acted as a spokesman for the occupation, drove the truck. It and the Jeep carried key leaders of the occupation that began Jan. 2. They were headed to a community meeting in John Day, with plans to spread their message against federal land control.

Instead, at 4:26 p.m., they were pulled over about 20 miles north of Burns.

Three occupants of the Jeep -- including Ammon Bundy, the son of controversial Nevada rancher Cliven Bundy and a leader of the refuge takeover - got out.

In another frame, the video shows another occupation leader, Ryan Payne, getting out of the truck driven by Finicum, with his hands up. Three others remained in the pickup with Finicum, Bretzing said.

As police stood by with guns trained on the truck, Payne was arrested. Finicum and his passengers remained in the idle truck for about four more minutes as officers hollered for them to surrender, Bretzing said.

That period was blacked out in the video, which resumed with footage of Finicum's truck speeding away from the scene. Officers trailed in a black SUV, and shots were fired at the truck. It rounded two bends in the road, then rammed into a snowbank to avoid a police roadblock. As it came to a stop, the truck nearly hit an officer who was standing alongside the road.

His hands raised, Finicum ran out of the car and toward the snowbank, yelling at police. Then, as police approached with guns drawn, he reached toward the left side of his waist. He began to put his hands back up, then reached down again.

Bretzing said Finicum was reaching toward a jacket pocket that contained a loaded 9 mm semi-automatic handgun.

The video shows Finicum being shot, then falling on his back. He raised his arm, then lay still.

"Actions have consequences," Bretzing said. "As the video clearly shows, it was a reckless action that resulted in consequences you have seen here today."

Finicum's truck, where three passengers remained, was stuck in the snowbank. Police released flash-bang devices, then capsules containing a tear gas-like substance. Once all passengers had left the pickup - about 10 minutes later - Finicum received medical attention.

Bretzing said troopers found two loaded .233 caliber semiautomatic rifles and one loaded .38 special revolver in the truck.

He wouldn't say how many times Finicum was shot, but acknowledged it was in the "single digits." He also wouldn't say whether Finicum had pulled his gun out of his pocket. The Deschutes County Major Incident Team is reviewing the shooting, a standard procedure in officer-involved shootings.

"We did everything we could to bring this to a peaceful resolution," Bretzing said.

Five people involved in the traffic stop were arrested while two were questioned and released. Those arrested were: Ammon Bundy, 40, of Emmett, Idaho; his brother, Ryan Bundy, 43, of Bunkerville, Nevada; Ryan W. Payne, 32, of Anaconda, Montana; Brian Cavalier, 44, of Bunkerville, Nevada; and Shawna J. Cox, 59, of Kanab, Utah.

Each was booked in the Multnomah County Detention Center, charged with a single count of conspiracy to impede officers from discharging their duties through the use of force, intimidation or threats. The crime carries a maximum six-year sentence and fines.

Separate from the traffic stop, police have arrested six more occupiers on the same charges. They are: Joseph Donald O'Shaughnessy, 45, of Cottonwood, Arizona; Jon Ritzheimer, 32, of Peoria, Arizona; Pete T. Santilli, 50, of Cincinnati; Jason Patrick, 43, of Bonaire, Georgia; Duane Leo Ehmer, 45, of Irrigon, Oregon, and Dylan Wade Anderson, 34, of Provo, Utah.

A vocal critic of federal land managers who participated in the 2014 standoff at Cliven Bundy's ranch, Finicum, 54, of Cane Beds, Arizona, had stopped paying the federal government to graze his cattle on public land. In recent days, he had tried to rally Harney County's ranchers to join him.

Conflicting accounts of how Finicum died have fueled rumors and rage, with some calling his death unjustified while others saying Finicum resisted arrest. In one account, Finicum was shot while his hands were in the air. In another, he was charging at officers.

The reports sparked outcry from groups who sympathize with the occupiers or with their message. The leader of the Pacific Patriots Network militia group issued a call Thursday for "thousands" of its members to descend upon Harney County to pressure the FBI into leaving.

Four occupiers remain in the refuge. Bretzing said law enforcement officials are working "round-the-clock" to get them out. The occupiers have said they won't leave unless officials agree not to charge them with crimes.
