Utah officials are investigating the role that so-called peacekeepers played in the killing of celebrated fashion designer Arthur Folasa Ah Loo on Saturday at the “No Kings” demonstration in Salt Lake City,

Utah resident Arthur Folasa Ah Loo, 39, died Saturday after he was shot during a large "No Kings" protest in downtown Salt Lake City. 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.

New video of the shooting at Saturday’s "No Kings" march shows the suspect running behind a fence and emerging in front of the people tasked with safeguarding protesters.
