Mark Adams Prieto was reportedly not very discreet about his plans to incite a race war, according to the FBI. 

The 58-year old Prescott man was arrested last month and after allegedly speaking with an undercover FBI agent about plans to shoot up a Bad Bunny rap concert in Georgia and allegedly sold two automatic rifles to the agent who Prieto believed was going to help him in his mass shooting plan. 

According to the unsealed indictment, by the U.S. Attorney’s Office of Arizona on Tuesday, where Prieto was charged with firearms trafficking, transfer of a firearm for use in a hate crime, and possession of an unregistered firearm.

An FBI agent accompanied the informant to a Crossroads of the West show on Jan. 20 this year to meet Prieto, who, the next day, allegedly asked the agent informant to help execute his plans to shoot-up a rap concert in Atlanta, Georgia.

According to the indictment, Prieto told the pair that he planned to target the concert because there would a lot of Black people there. 

Prieto’s plan was to enlist the informant’s help with a cache of weapons in Atlanta before the shooting and then on a separate trip, the feds say.

The informant said that Prieto had allegedly begun advocating for mass shootings against “Blacks, Jews, or Muslims,” and that he believed, the shooting should take place before martial law is enacted following the 2024 presidential election. Prieto did not know that the agent and informant were working with the FBI.

Reportedly Prieto was at a Crossroads of the West gun show where he allegedly sold an AK-47 to the agent for the attack and bought a pistol for himself for the attack. 

The next month, Prieto was boothing at the Crossroads of the West gun show where he had machine guns, rifles, shot guns and pistols strewn about. Prieto is accused of selling an AR-15 to the agent at the show, intended to be used for the shooting.

“Yeah, yeah we gotta do it,” he allegedly told the agent, adding that waiting too long might jeopardize the plan.

Prieto identified a Bad Bunny concert being held on May 14-15 at the State Farm Arena as the target of the attack. 

Prieto, allegedly, planned to scout the concert venue in May after visiting his mom in Florida, and then meet his two purported accomplices back on June 1 and 2 during the next gun show.

However, on May 14, while Prieto was driving through New Mexico en route to Florida, was  arrested and admitted to planning the attack on a “rock concert where young people and minorities [would be],” according to the indictment.
