Overview

• About 10,000 people marched through downtown Salt Lake City on June 14 to protest President Trump’s policies under the “No Kings” banner.
• Officers say Arturo Gamboa brandished an AR-15-style rifle near State Street and ran toward the crowd, prompting intervention.
• Two volunteers in neon vests fired three rounds at Gamboa, inadvertently killing 39-year-old Arthur Folasa Ah Loo, an innocent bystander.
• Gamboa was found with a minor gunshot wound, taken into custody minutes later and booked on a murder charge by Salt Lake County prosecutors.
• Salt Lake City Police continue probing Gamboa’s motives and the actions of the peacekeeping team that opened fire.
