Arthur Folasa Ah Loo, the man who was shot and killed at a “No Kings” protest in Salt Lake City, appeared in four episodes of the 2017 season of “Project Runway."

Arthur Folasa Ah Loo, 39, a Samoan-born fashion designer, was participating in an anti-Trump protest in Salt Lake City on Saturday when he was shot by a man working security, the police said.

Salt Lake City police are investigating the roles of two self-described "peacekeepers" following a fatal shooting at Saturday's protest that left one person dead and another injured, raising questions about unauthorized security at public demonstrations.

At least one person was critically injured in a shooting during a ‘No King’ protest in Salt Lake City, Utah. Salt Lake City police said they have taken three people into custody after the “No Kings” m

Detectives believe the victim was at the demonstration as a bystander and “was not the intended target of the gunfire.”

At 7:56 p.m., Redd said a police officer heard shots near 151 S. State St. First responders soon found Ah Loo injured on the ground. Medics quickly surrounded him, offering aid, but he died later at a local hospital.
