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.

Arthur Folasa Ah Loo, a 39-year-old former contestant on the fashion design competition series, died Saturday after being struck by gunfire, as police refer to him as an “innocent bystander.”

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.

SALT LAKE CITY (KUTV) — The man who was fatally shot during the Salt Lake City "No Kings" protest was a fashion designer with a local company and a former contestant on Bravo's "Project Runway." Police identified the victim of Saturday's shooting as Arthur Folasa "Afa" Ah Loo.

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