Charging documents filed late Tuesday say the shooting occurred early Sunday morning during a party at a large events space in Browns Canyon, which can be rented on Airbnb.
The shooting began as a verbal dispute between party organizers and a group of men they’d kicked out of the event.
According to court papers, security footage shows the men went to their cars but returned—one of them flashing a weapon.
Party organizer Manuel Pimentel-Gonzalez, 23, then retrieved what investigators believe was a Draco 9mm submachine gun from a white BMW X7. After being surrounded by the organizers, the other group retreated to their vehicles, court papers say.
Francisco Romero-Fuenmayor, also 23 and a party organizer, also allegedly fired shots into the air above the retreating group.
That set off a shootout injuring at least two people. One of the men kicked out of the party was shot in the hand, and Pimentel-Gonzalez was shot in the back. Neither of the injuries were life-threatening.
In all, investigators found 42 shell casings, four firearms and multiple cartridges at the scene. They also confiscated 11 phones, according to court documents.
Pimentel-Gonzalez was located at a residence in Eagle Mountain, where investigators also found the white BMW with three bullet holes in it. Authorities transported him to Intermountain Medical Center before taking him to the Summit County jail.
When investigators contacted Romero-Fuenmayor, arrest papers say, he told the deputies he was at the party and participated in the shootout.
Deputies also arrested 22-year-old Alejandro Carreno-Romero, whom witnesses said is known as “Tuqi.” They told deputies Tuqi was among the organizers and was firing a .45 caliber pistol.
Authorities arrested 18-year-old Jose Enrique Zuniga-Diaz May 21. They say security footage shows him firing from behind a car and that he admitted to participating post-Miranda.
Summit County prosecutors charged all four men with five second-degree felony counts of discharge of a firearm. Under Utah law, a second-degree felony is punishable by a prison term of between one and 15 years.
There are gang enhancements attached to some of the charges, which could add additional penalties, but it wasn’t immediately clear whether the men are members of a gang. The men currently in custody are being held without bail.
Charging documents show Pimentel-Gonzalez faces additional charges of possessing a firearm as a restricted person and aggravated assault, second and third degree felonies respectively, and he pleaded "not guilty" Wednesday.
