WATCH: FBI releases LaVoy Finicium shooting video showing he went for his gun — twice

The FBI released video that clearly shows LaVoy Finicum reached toward his waist -- twice -- before he was fatally shot by law enforcement officers.

Investigators released the full, 26-and-a-half video recorded from a helicopter overhead in hopes of knocking down conspiracy theories about the Arizona rancher's death.

His supporters, and one eyewitness, claimed Finicum died with his hands up in surrender.

The video, at about the 9:20 mark, shows Finicum jump out of his SUV with his hands outstretched from his sides after crashing into a snowbank.

One officer approaches from the front with a gun drawn, and Finicum reaches with his left hand toward the right side of his body.

He lifts his arms again and then turns to see a second officer come out of a wooded area behind him.

Finicum again reaches with his right hand toward the left side of his body, and the second officer shoots him.

It's not clear how many rounds the officer fired, but the rancher falls to the snow, mortally wounded.

Investigators said Finicum was carrying a loaded 9 mm handgun in the left pocket of his jacket, and authorities said they had been warned that the militants were most likely armed.

The video does not appear to show any officers fire on the vehicle Finicum had been driving, although the flashes from stun grenades can be seen.

“As soon as the agents and troopers were confident that they had addressed any further threats, they provided medical assistance to Finicum," "said Greg Bretzing, the FBI special agent in charge. "That happened about 10 minutes after the shooting.

Agents and troopers did find 3 other loaded weapons inside the truck. They included two loaded .223 caliber semi-automatic rifles. There was also one loaded .38 special revolver.”

Victoria Sharp, an 18-year-old singer riding in the SUV, said she heard about 100 shots fired on the vehicle after Finicum was shot.

Another militant, who was riding in another vehicle stopped by authorities, said two of Finicum's passengers claimed he charged officers after exiting the vehicle.

Nevada Assemblywoman Michele Fiore claimed Ammon Bundy called his wife to say he watched Finicum shot to death on his knees or lying down -- but none of those accounts appear to be accurate, based on video evidence, which seems to match accounts given by law enforcement.

The officers retreated behind their own vehicles for several minutes, before gradually closing in on the SUV, and eventually the other occupants get out.

Each of them lifts their arms high in surrender and walks very slowly away from the vehicle.

Finicum had fled a traffic stop that resulted in the arrests of several other militants, including leader Ammon Bundy, and nearly ran over an FBI agent as he tried to drive on to Grant County -- where he believed the sheriff would protect him.

He had repeatedly stated that he would rather die for his interpretation of the U.S. Constitution than spend any time in jail.

Eight of the militants were arrested the night Finicum was killed, and most of the other militants ran away from the Malheur National Wildlife Preserve within hours.
