It was unclear whether Mr. Dolloff, whose surname is spelled in jail records as Doloff, had been charged on Sunday. He had a court hearing on Sunday morning, records show, but an arrest affidavit was sealed. The district attorney did not respond to requests for comment and it was unclear if Mr. Dolloff had a lawyer.
The victim, who was identified only as a white man, was taken to the hospital, where he died, Joe Montoya, chief of the Police Departments investigations division, said at a news conference on Saturday.
The victim was a member of a biker group that provided volunteer security services for the Patriot Muster, said Weston Imer, a supporter of the group who witnessed the shooting.
One of the organizers of the right-wing protest, John Tiegen, said on Instagram on Sunday that he was deeply saddened to learn of the tragic death of a fellow American patriot, but he said it was unclear whether the victim had been at the rally or just in the vicinity.
