Police say Arturo Gamboa was carrying a rifle when safety volunteer fired on him and accidentally killed bystander

A man jailed on suspicion of murder for allegedly brandishing a rifle at a “No Kings” rally in Utah before an armed safety volunteer fired and inadvertently killed a protester has been released from custody.

Local district attorney Sim Gill’s office said on Friday that it was unable to make a decision on charges against Arturo Gamboa after the 14 June shooting that killed demonstrator Arthur Folasa Ah Loo – but that the investigation into the slaying continues.
