This location marked with cairns along US 395 north of Burns, Oregon is where LaVoy Finicum was shot & killed by Oregon State Police during a roadblock on January 26, 2016 near the Joaquin Miller Horse Camp.  He was one of the militants of the 2016 Malheur National Wildlife Refuge occupation.  At the time the standoff was receiving a lot of media coverage.  From Wikipedia:

On January 2, 2016, an armed group of far-right extremists seized and occupied the headquarters of the Malheur National Wildlife Refuge in Harney County, Oregon, and continued to occupy it until law enforcement made a final arrest on February 11, 2016. Their leader was Ammon Bundy, who participated in the 2014 Bundy standoff at his father's Nevada ranch. Other members of the group were loosely affiliated with non-governmental militias and the sovereign citizen movement.

The organizers were seeking an opportunity to advance their view that the federal government is constitutionally required to turn over most of the federal public land they manage to the individual states, in particular land managed by the Bureau of Land Management (BLM), United States Fish and Wildlife Service (USFWS), United States Forest Service (USFS), and other agencies. In 2015, the militants believed they could do this by protesting the treatment of two area ranchers convicted of federal land arson, who they believed were wrongly convicted. This is despite the fact that the men in question, father and son Dwight and Steven Dwight Hammond, did not want their help. The occupation began when Bundy led an armed party to the refuge headquarters following a peaceful public rally in the nearby city of Burns.

By February 11, all of the militants had surrendered or withdrawn from the occupation, with several leaders having been arrested after leaving the site; one of them, Robert LaVoy Finicum, was shot and killed during an attempt to arrest him after he reached toward a handgun concealed in his pocket after he tried to evade a roadblock; Ryan Bundy was wounded. More than two dozen of the militants were charged with federal offenses including conspiracy to obstruct federal officers, firearms violations, theft, and depredation of federal property.

January 26 shooting:

On January 26, Finicum was one of several occupation leaders who left the refuge (located in Harney County) in a two-truck convoy. The convoy also included occupation leaders Ammon Bundy, Ryan Bundy, Shawna Cox, and Ryan Payne and two supporters, Victoria Sharp and Brian Cavalier. Their intention was to speak at a public meeting in John Day, Grant County. Finicum was driving his white 2015 Dodge Ram pickup truck, followed by a dark-colored Jeep.

State and federal authorities used the opportunity to intercept them with a two-phase operation involving a traffic stop and a roadblock about two miles further along the highway. Both were set up on an unpopulated stretch of U.S. Route 395 in Harney County. The operation had originally been planned for a location in adjacent Grant County, but was moved to Harney County because the Federal Bureau of Investigation (FBI) and Oregon State Police (OSP) considered the Grant County sheriff, Glenn Palmer, to be a security leak due to favorable comments he had made with respect to the militants. Authorities feared a militia response, and a location was selected with poor cell phone service.

As the convoy entered the operation area, vehicles driven by the FBI and the OSP pulled in behind the Jeep. When the Jeep pulled over, Ammon Bundy and Brian Cavalier were peacefully arrested. The driver of the Jeep, Mark McConnell, who was a government informant and the only occupant of the vehicle with a firearm, was not arrested or charged.

Driving the lead vehicle, Finicum initially kept going but eventually stopped as well. Police fired a 40mm plastic-tipped round of pepper spray, which hit the top of Finicum's truck. At that point, Ryan Payne exited Finicum's truck and surrendered peacefully. Finicum's other passengers, Ryan Bundy, Shawna Cox, and Victoria Sharp, remained in his truck.

After Payne's surrender, Cox and Bundy each started recording cell phone videos of the confrontation. The videos captured police identifying themselves as Oregon State Police and ordering Finicum to turn off his engine. Refusing their order, Finicum yelled back that he was going to meet Palmer and that the only way officers could prevent that meeting was to shoot him. Finicum yelled at the troopers, "You back down or you kill me now. Go ahead. Put the bullet through me. I don't care. I'm going to go meet the sheriff. You do as you damned well please."

About seven minutes after stopping his truck, Finicum drove away with his three remaining passengers at high speed. They were pursued by officers. About 1 mile (1,609 m) later, Finicum rounded a bend and spotted the roadblock. Trying to avoid a spike strip, Finicum braked and swerved. His truck plunged into deep snow, narrowly missing an FBI agent.

When Finicum's truck became stuck in the snow, he immediately exited the vehicle, just as two shots were fired by an FBI agent. One shot struck the roof of Finicum's truck and the other went wide. These shots became the subject of controversy because the FBI agents initially failed to disclose them.

Meanwhile, Finicum moved about in the snow, alternating between holding his hands above his head and seemingly reaching into his jacket, where officers later found a loaded semi-automatic weapon. OSP officers and FBI agents armed with rifles positioned themselves along the road, while an OSP officer, who had holstered his firearm and equipped himself with a nonlethal Taser X2, walked toward him from the treeline with the intention of subduing him. As Finicum moved his hands down, he turned towards the approaching taser-holding officer and repeatedly yelled, "You're going to have to shoot me!" The troopers believed Finicum to be armed and considered his hand position to signal an imminent threat to the life of the taser-holding officer; Finicum was holding his jacket with his left hand and reaching for a pocket with his right hand. Two troopers fired a total of three times, and a third who was about to fire held back, realizing a fourth shot was not needed. Medical assistance was given to Finicum approximately 10 minutes after the shooting.

Ryan Bundy received a minor shrapnel wound during the incident.

There is a recently erected memorial to LaVoy Finicum a few hundred feet down the highway going north on the left side by milepost 51C.  Videos of the shooting can be found on Youtube.
