A newly unsealed affidavit ties a second Missouri man, Jordan Rincker, to a multi-state conspiracy that federal prosecutors say plotted a drone-and-shooter attack at the UFC Freedom 250 on June 14 and even discussed striking a FIFA World Cup match in Kansas City on July 3, 2026.

Federal prosecutors charged Jordan Rincker with conspiracy to commit murder after investigators linked him to encrypted chats used by members of the alleged group. The indictment names at least seven publicly identified defendants and lays out a plot that federal agents say combined explosive-laden drones and armed attackers aimed at a high-profile public event at the White House.

Rincker is from the St. Joseph, Missouri, area and his charges were filed in the Western District of Missouri earlier this month. Co-defendant Daniel Eskridge of Kidder, Missouri, was charged last week, and Abraham Hermosillo Alvarez is named as the alleged ringleader in the filings.

Investigators say the plot centered on the UFC Freedom 250 event at the White House on June 14 and was disrupted on June 10 after a mother alerted police about her 19-year-old son’s firearms purchases and online messages. That tip triggered a chain of investigative moves that federal officials credit with stopping the plan before it reached the crowd.

The unsealed affidavit expands the scope of the case as new filings arrive, showing coordinated conversations and money transfers across state lines. Federal agents describe a cell using encrypted apps to share maps, aerial photos, and operational details that moved the scheme beyond idle talk.

Rincker was tied to a username on an encrypted messaging app used by at least six members of the alleged network, and the affidavit says he discussed building drones that could carry “payloads.” At a meeting in Omaha, Nebraska, he allegedly accepted $1,200 in cash, a 3D printer, and tactical gear from another suspect.

Searches of Rincker’s home and a storage unit reportedly turned up firearms, ballistic gear, night-vision equipment, multiple 3D printers, and 3D-printed gun parts. Rincker, 28, was arrested in Missouri on Sunday and now faces a conspiracy-to-commit-murder charge that carries a potential life sentence.

Court filings describe a coordinated assault concept: drones loaded with explosives strike the crowd while armed conspirators shoot fleeing attendees. Roughly 20 participants are said to have communicated in encrypted channels, sharing the kinds of operational details you would expect in a planned mass-casualty event.

The alleged ringleader, Alvarez, has drawn separate scrutiny over his immigration status, and the filings say Rincker accepted a $1,200 payment from Alvarez while also sending $100 to fund another suspect’s trip from California to Washington, D.C. Those cash movements are the kind of low-tech logistics that often tie together multi-state plots.

Court documents describe Eskridge as a recruiter and organizer within the group, though the latest public filings did not spell out his full set of charges. Prosecutors are still sorting roles and responsibilities as the investigation expands.

One particularly alarming line in the affidavit shows the group discussed an attack on a FIFA World Cup match scheduled for July 3, 2026, at Arrowhead Stadium in Kansas City, Missouri. The same encrypted channels that planned the White House operation reportedly contained the World Cup talk.

“Based on my training and experience, I believe in the above conversation includes a discussion by (co-defendant Abraham Hermosillo Alvarez) in which Alvarez identifies the FIFA World Cup as a potential target advises that they should prepare for an attack on July 4, 2026, and he is telling the other coconspirators to prepare to come to Missouri.”

The affidavit continued: “I know that there is a FIFA World Cup match scheduled to occur on July 3, 2026, in Kansas City, Missouri. Accordingly, I believe that Rincker is sharing Alvarez’s idea to target the FIFA World Cup match on July 3, 2026.”

With that match fewer than two weeks away, the discussion—whether aspirational or operational—has focused law enforcement on Kansas City’s security posture. Officials still need to determine if the group had the capacity to carry out a second attack or if the chatter remained at the planning stage.

Authorities also charged William Lee Spartacus Falkner of Washington state with conspiracy to commit murder, bringing the number of publicly identified federal defendants to seven. Falkner allegedly joined a Telegram drone-operations chat on June 7 and discussed heavy explosive payloads, anti-jamming measures, and fiber optic controls for drones.

After initial arrests became public, Falkner allegedly texted a co-conspirator: “Work trip is canceled. My boss got picked up.” Investigators say encrypted chat logs have identified as many as 19 additional individuals who may be connected, and the Justice Department has signaled the probe remains active.

The early disclosure of the drone plot before every arrest was complete reportedly caused tension between agencies, but the steady stream of new charges suggests investigators are methodically dismantling the network. That methodical approach appears to favor prevention over post-attack response.

“This case demonstrates the effectiveness of our law enforcement partners and U.S. Attorneys working together to prevent violence before it can take place. We will continue taking decisive action against those who seek to endanger national security and threaten the safety of Americans. By staying proactive, we will disrupt their operations, break apart their networks, and hold those responsible accountable under the law.”

“We made a bunch of probable cause arrests before the (UFC) event, we assured the event was safe. We were watching a whole bunch of others to ensure that nobody had come to DC,” Raia said. “But we’re continuing to make those cases. And so that’s why you’re seeing folks get kind of picked off.”

“Law enforcement continues to do what it does, move to disrupt and hold accountable those allegedly plotting to do harm on the White House Grounds on June 14.”

The White House has seen multiple security incidents in recent months, which has put significant pressure on the Secret Service and federal partners to maintain a credible deterrent. That pressure is part of the backdrop for why early disruption matters so much in this case.

Significant questions remain: whether Alvarez is in custody or at large, who else in the suspected 20-person network will face charges, and what specific federal statutes will underlie the conspiracy counts. Public filings have left those details incomplete as the probe continues.

The affidavit’s phrasing—”I believe that Rincker is sharing Alvarez’s idea”—reflects an investigator’s interpretation of encrypted messages rather than a sealed, operational plan. But where procurement, cash transfers, and weapons stockpiles appear in filings, even preliminary targeting discussions cannot be dismissed.

FBI Director Kash Patel said the latest arrests reflect the bureau “teaming up with our great partners, to identify and apprehend those who allegedly wanted to attack the UFC Freedom 250 event, a threat this FBI and our partners prevented.”

Seven defendants charged and as many as 19 more identified. A disrupted attack at the White House and a discussed follow-up aimed at Kansas City. A mother’s call to police may have stopped the worst of it, but the question now is whether the full network has been found and whether Kansas City is ready for July 3.
