Suspect Arturo Gamboa did not fire any shots at the Salt Lake "No Kings" protest, but could face a murder charge for his alleged involvement in a bystander's de

The "No Kings" protest in Salt Lake City was struck by violence when a man allegedly brandished a rifle near the crowd.

As prosecutors consider potential criminal charges against the man whose alleged actions caused the shooting death of another man during Saturday's "No Kings" protest, the investigation into the so-called "peacekeeper" who actually fired the fatal shot also continues.

Friends of Arturo Gamboa say they don't believe he ever brandished the weapon. Instead, they believe the shooting was a deadly miscommunication — someone overreacting because he was open-carrying.
