Salt Lake City, UT — The law firm of Parker & McConkie, on behalf of the surviving spouse of Arthur “Afa” Folasa Ah Loo, welcomes the decision by Salt Lake County District Attorney Sim Gill to file manslaughter charges against Matthew Scott Alder, the self-described “peacekeeper” who shot and killed Mr. Ah Loo during the June 14, 2025 “No Kings” rally in downtown Salt Lake City. Criminal charges were filed in Utah State Court, Case No. 251915142 , on December 3, 2025.
The charging documents allege that while the first two shots Alder fired may have been in self-defense, the fatal third shot — fired over a crowd of peaceful demonstrators — was reckless and unjustified under Utah law.
Jim McConkie of Parker & McConkie said his client is “pleased that District Attorney Sim Gill has chosen to prosecute Matt Alder, the so-called peacekeeper involved in the shooting death of her husband.”
Mr. McConkie emphasized that his client “will cooperate fully with the prosecutors and the justice system. We will be right there pushing along with them.” He added that he hoped “the pursuit of this case will help all of us understand what circumstances brought about this tragic loss of life.”
Attorney Brian Stewart of Parker & McConkie emphasized that this is just a first step toward justice for the Ah Loo family, stating that, “In the coming weeks we will be filing a wrongful death lawsuit against Alder, who killed Afa. The civil lawsuit will allow us opportunity through the discovery process and the subpoena power to more fully investigate the incident and ensure that all the appropriate parties are held accountable and necessary changes are made.”
Mr. McConkie also echoed those sentiments, expressing his hope that “as more information emerges, it will result in reforms and improved oversight of public events by city officials and law enforcement agencies across the state.”
