(CNN) The weeks-long armed occupation of a federal wildlife refuge headquarters in Oregon suffered two major blows when protest leader Ammon Bundy was arrested and another key figure was killed.

Bundy and several fellow occupiers were pulled over Tuesday on U.S. Highway 395, a law enforcement official said. According to The Oregonian , they were headed to the city of John Day, where they planned to participate in a community meeting set up by local residents.

Everyone obeyed orders to surrender except LaVoy Finicum and Ryan Bundy, Ammon Bundy's brother, the official told CNN.

Shots were fired, but it's unclear who fired first, the source said. Ryan Bundy was wounded, and Finicum died.

With their leader Ammon Bundy in police custody and their spokesman, Finicum, dead, it's unclear if the remaining occupiers will dig in their heels at the Malheur National Wildlife Refuge, which they have occupied for 26 days -- or if their resolve will wane.

Occupiers: 'A patriot has fallen'

Finicum was one of the most outspoken occupiers who took over the refuge building near Burns on January 2 to protest federal land policies.

Earlier this month, the father of 11 told CNN he doesn't want to die -- but would never go behind bars.

"I'm just not going to prison," Finicum said. "Look at the stars. There's no way I'm going to sit in a concrete cell where I can't see the stars and roll out my bedroll on the ground. That's just not going to happen. I want to be able to get up in the morning and throw my saddle on my horse and go check on my cows. It's OK. I've lived a good life. God's been gracious to me."

LaVoy Finicum took down what he claimed to be a government spy camera in Oregon on January 15.

News of Finicum's death quickly reached the protesters still holed up at the refuge building.

"It appears that America was fired upon by our government," the occupiers said on the Bundy Ranch Facebook page . "One of liberty's finest patriots is fallen. He will not go silent into eternity."

The occupiers also claimed Finicum had his hands in the air when he was shot.

Nevada Assemblywoman Michele Fiore said Ammon Bundy called his wife, Lisa Bundy, from the back of a police car on Tuesday night and said Finicum was cooperating with police when he was shot, according to The Oregonian.

Fiore has been a vocal supporter of the Bundy family.

Fiore's account couldn't be independently corroborated. A representative from the Joint Information Command Center in Harney County said authorities had no comment on the claim that Finicum had his hands up. He said more information would be released Wednesday.

Bundy's father, controversial Nevada rancher Cliven Bundy, said Finicum died supporting his beliefs.

"He was a wonderful man," he told CNN affiliate KTNV . "He was a student of the Constitution. He was interested in freedom, and I think he gave his life where he felt it was best."

The arrests

In all, police arrested eight people Tuesday linked to the wildlife refuge takeover: five in the traffic stop on Highway 395; two others in Burns; and one in Arizona.

The five arrested at the traffic stop were Ammon Bundy, Ryan Bundy, Brian Cavalier, Shawna Cox and Ryan Waylen Payne.

The two arrested in Burns were Joseph Donald O'Shaughnessy and Peter Santilli.

And protester Jon Ritzheimer, who previously made headlines for leading an anti-Islam protest in Arizona, turned himself in to police in Peoria, Arizona, FBI spokesman Kurt Remus said.

All eight people arrested face a federal felony charge of conspiracy to impede officers of the United States from discharging their official duties through the use of force, intimidation or threats, the FBI and Oregon State Police said.

Ammon Bundy and others started out protesting the sentencing of Dwight Hammond and his son Steven, ranchers who were convicted of arson on federal lands in Oregon.

But a January 2 march supporting the Hammonds led to the armed occupation of the refuge, with protesters decrying what they call government overreach when it comes to federal lands.

Since then, the occupiers have turned the refuge into their own -- changing the sign in the front and tearing down a fence they claimed harmed the livelihood of a rancher. But that rancher told The Oregonian he didn't ask the occupiers to tear down the public fence -- in fact, he was upset by it.

Ammon Bundy has said that while the armed protesters don't want violence, they would be ready to defend themselves if necessary.

But with the leader arrested, it's not clear what will happen next.

On Tuesday night, Oregon Gov. Kate Brown stressed that the occupation at the refuge was not over.

"The situation in Harney County continues to be the subject of a federal investigation that is in progress," she said. "My highest priority is the safety of all Oregonians and their communities. I ask for patience as officials continue pursuit of a swift and peaceful resolution."
