(CNN) -- Two Alaska state troopers -- both of whom had appeared on a National Geographic reality show by that name -- have been killed in a confrontation on the dirt streets of an isolated Alaska village.
The bodies of Sgt. Patrick "Scott" Johnson and Trooper Gabriel "Gabe" Rich were recovered from Tanana, a remote village 130 miles west of Fairbanks, on Friday, the day after they were reported killed, the Alaska Department of Public Safety said.
Their colleagues have since taken two men into custody in that village, which is on the Yukon River in the state's interior.
One of them --19-year-old Nathanial Lee Kangas of Tanana -- is under arrest in both deaths, the state public safety department said, adding that formal murder charges are being prepared. The other is Arvin Morse Kangas, 58, accused of fourth-degree assault and driving with a revoked license in a separate incident.
Neither could be immediately reached for comment.
In a post Friday on their Facebook page, the Alaska State Troopers said they are "reeling from the loss" of their slain colleagues, both of whom worked out of the agency's Fairbanks rural service unit.
Born in Fairbanks, Johnson worked three years for the North Slope Borough Police before becoming an Alaska State Trooper in 1993. Here, he held several roles including trooper, field training officer, canine officer, narcotics team supervisor and rural unit sergeant. It's in the latter that the 45-year-old died, leaving behind a wife and three daughters, according to the Alaska State Troopers.
Rich moved to Fairbanks shortly after being born in Pennsylvania, then went on to work for the North Pole Police and, starting in 2011, with the Alaska State Troopers. The 26-year-old is survived by his fiancee and two sons.
Both gained a degree of widespread recognition thanks to their appearance on the National Geographic channel's "Alaska State Troopers," a reality show that the network says follows "one of the toughest law enforcement agencies in the nation."
Rich appeared in six episodes of "Alaska State Troopers" in 2012 and 2013, according to IMDb.com. Johnson was in four episodes from 2011 to 2013, according to the site.
The troopers were not with a film crew when they died and are not slated for any future episodes, said National Geographic Channel spokesman Chris Albert said. The channel has pulled repeats of episodes featuring the slain troopers, he said.
"We have a long and proud association with the troopers, and consider them a member of our extended channel family," Albert said in a statement. "We send our deepest condolences to their families and the entire Alaska State Trooper force."
Newspaper: Troopers shot after botched sale of couch
CNN affiliate KTVF reported that the officers had headed to the village to follow up on a report from the previous night of someone brandishing a gun.
The Alaska Dispatch website reported that the troopers were shot after an unarmed village public safety officer called for backup after an altercation involving the botched sale of a $150 couch.
The news site said two people had been arrested, one after a lengthy standoff with heavily armed police.
Video from CNN affiliate KTUU showed heavily armed authorities -- some of them wearing camouflage -- walking along a dirt road in Tanana, as well as one man being led away in handcuffs.
Gov. Sean Parnell mourned the loss of the two officers.
"These fallen heroes answered the call to serve and protect, and made the ultimate sacrifice, while keeping our communities safe," the governor said in a statement. "May God and the loving support of grateful Alaskans bring comfort to the families of these courageous men."
According the the U.S. Census Bureau, 254 people live in Tanana. The village is located near the confluence of the Tanana and Yukon rivers in Alaska's vast rural interior.
No roads lead into the village, which is accessible only by air.
Images of the village published online show a town of log-cabin buildings and ramshackle structures along the banks of the Yukon River. The village boomed in the late 1800s and early 1900s with the discovery of gold in the region.?
