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,

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.

At least one person was critically injured Saturday in a shooting at a protest against President Donald Trump in Salt Lake City. It came hours after two Democratic lawmakers in Minnesota were shot dead by a gunman.
