SALT LAKE CITY (AP) — A military veteran who was trying to stop an alleged gunman and inadvertently shot and killed a demonstrator at a Salt Lake City “No Kings” rally was a “safety volunteer” for the demonstration, according to police and organizers.

Utah resident Arthur Folasa Ah Loo, 39, was shot and critically wounded during the protest in Salt Lake City on Saturday, June 14. He later died in the hospital from his injuries, the Salt Lake City Police Department confirmed in a news release.

Police responded to a shooting incident at a protest near 151 South State Street in Utah on the evening of Saturday, June 14. One person was found with a 'critical gunshot wound' and was transported to the hospital,
