A safety volunteer accused of fatally shooting a man taking part in a June No Kings protest in Salt Lake City, while firing at another armed man he believed to be a threat, was charged with manslaughter on Wednesday.
Matthew Scott Alder, 43, was charged with one count of manslaughter. Alder opened fire during the protest on 14 June after seeing another man, Arturo Gamboa, carrying a rifle. Alder told investigators that he believed Gamboa, 24, was about to commit a mass shooting, so he fired three shots, wounding Gamboa but killing a bystander, Arthur “Afa” Ah Loo. Ah Loo was recording video of protesters in the street when he was fatally shot.
