Arturo Gamboa was identified as the suspect in the shooting of 39-year-old Arthur Folasa Ah Loo at a 'No Kings Day' protest in Salt Lake City

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.

Ah Loo — an "innocent bystander," fashion designer and former "Project Runway" contestant — was shot by a member of a "peacekeeping" group who fired at a gunman who had an AR-15 style rifle and who witnesses say was running toward the crowd.

St. Mark's Cathedral in Salt Lake City served as a refuge for protesters during a march against President Trump.
