The Oregonian reports that an Arizona rancher was killed when authorities arrested leaders of an armed group that has been occupying a national wildlife refuge.

Authorities did not identify the person killed, saying only that it was an adult male who died in an "officer involved shooting" during law officers' confrontation with Ammon Bundy and his followers during a traffic stop outside Burns, Oregon.

However Arianna Finicum Brown told the Portland, Oregon, newspaper that the man killed was her father - 55-year-old Robert "LaVoy" Finicum of Cane Beds, Arizona. LaVoy Finicum was a frequent and public presence at the Malheur National Wildlife Refuge, often speaking for the group at news conferences.

The FBI says one of the occupiers of the wildlife refuge in Oregon has surrendered to police in Arizona, raising the total number of arrests to eight.

FBI said Jon Eric Ritzheimer turned himself in Tuesday night at the police department in Peoria, Arizona.

Like the others who were arrested, Ritzheimer faces a felony charge of conspiracy to impede federal officials in their official duties through the use of force, intimidation or threats.

The 32-year-old Ritzheimer was among the most visible of the occupiers at the Malheur National Wildlife Refuge.
