Around 8 p.m., officers and detectives – including members of SLCPD’s Violent Criminal Apprehension Team (VCAT) and Gang Unit – were flagged down near 102 South 200 East.
There, they found a man crouching among a group of people with a gunshot wound.
That man is identified as 24-year-old Arturo Gamboa, who was dressed in all black clothing and wearing a black mask.
As officers approached, community members pointed out a nearby firearm, which was described as an AR-15-style rifle.
Officers also located a gas mask, black clothing, and a backpack in close proximity. The items were collected and processed by the SLCPD Crime Lab.
Paramedics took Gamboa to the hospital. Detectives later booked Gamboa into the Salt Lake County Metro Jail on a charge of murder.
Officers also detained two men who were wearing high-visibility neon green vests and carrying handguns.
These men were apparently part of the event’s peacekeeping team.
During interviews, detectives learned the two peacekeepers saw Gamboa move away from the crowd and move into a secluded area behind a wall – behavior they found suspicious.
One of the peacekeepers told detectives he saw Gamboa pull out an AR-15-style rifle from a backpack and begin manipulating it.
The peacekeepers drew their firearms and ordered Gamboa to drop the weapon.
Witnesses reported Gamboa instead lifted the rifle and began running toward the crowd gathered on State Street, holding the weapon in a firing position.
In response, one of the peacekeepers fired three rounds.
One round struck Gamboa, while another tragically wounded Mr. Ah Loo.
Detectives have not been able to determine, at this time, why Gamboa pulled out his rifle and began to manipulate it or why he ran from the peacekeepers when they confronted him.
The peacekeepers immediately attempted to provide aid to the injured bystander.
Detectives are still actively investigating this case, to include the actions of the peacekeepers.
Detectives have developed probable cause that Gamboa acted under circumstances that showed a depraved indifference to human life, knowingly engaged in conduct that created a grave risk of death and ultimately caused the death of an innocent community member.
“Our detectives are now working to thoroughly investigate the circumstances surrounding this incident,” Chief Redd added. “We will not allow this individual act to create fear in our community.”
