Federal prosecutors have charged a second Missouri man, Jordan Rincker, with conspiracy to commit murder in connection with an alleged mass-casualty attack plot targeting a UFC event at the White House, and a newly unsealed affidavit shows the group also discussed striking a FIFA World Cup match in Kansas City.

Rincker, from the St. Joseph, Missouri, area, is one of at least seven defendants now publicly identified in the case, KMBC reported. His charges were filed earlier this month in the Western District of Missouri. A co-defendant, Daniel Eskridge of Kidder, Missouri, was charged last week. The alleged ringleader, Abraham Hermosillo Alvarez, is also named as a co-defendant.

The case centers on a plot that federal investigators say involved explosive-laden drones and armed attackers targeting the UFC Freedom 250 event held at the White House on June 14. Authorities disrupted the plan four days earlier, on June 10, after the mother of a 19-year-old Ohio suspect alerted police about her son's firearms purchases and online communications, the Washington Times reported.

That tip may have prevented a catastrophe. But the scope of the alleged conspiracy, and the ambitions of those involved, continues to expand with each new court filing.

Drones, 3D-printed weapons, and encrypted chats

Federal investigators connected Rincker to a username on an encrypted messaging app used by at least six members of the alleged group. The affidavit describes Rincker discussing the construction of drones capable of carrying "payloads." At a meeting in Omaha, Nebraska, he allegedly accepted $1,200 in cash, a 3D printer, and tactical gear from another suspect.

When agents searched Rincker's home and storage unit, they discovered firearms, ballistic gear, night-vision equipment, multiple 3D printers, and 3D-printed gun parts, the Washington Examiner reported. Rincker, 28, was arrested in Missouri on Sunday. He faces a conspiracy to commit murder charge that carries a potential life sentence.

The broader plot, as described in court filings, envisioned a coordinated assault: drones loaded with explosives would strike the crowd, and armed conspirators would then shoot attendees as they fled. Roughly 20 participants communicated through encrypted messages, sharing detailed maps and aerial photographs of the White House grounds.

The alleged ringleader, Alvarez, has drawn separate scrutiny over his immigration status. Rincker allegedly accepted a $1,200 payment from Alvarez and also sent $100 to fund another suspect's drive from California to Washington, D.C.

Court documents describe Eskridge as a recruiter and organizer within the group. His specific charges were not detailed in the latest filings.

World Cup match in Kansas City flagged as potential target

Perhaps the most alarming detail in the newly unsealed affidavit is a discussion among the alleged conspirators about targeting a FIFA World Cup match scheduled for July 3, 2026, at Arrowhead Stadium in Kansas City, Missouri.

An investigator wrote in the affidavit:

"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."

That match is now fewer than two weeks away. Whether the alleged conspirators had the operational capacity to carry out a second attack remains an open question, but the fact that it was discussed at all, in the same encrypted channels used to plan the White House plot, will rightly focus law enforcement attention on Kansas City's World Cup security posture.

A seventh defendant and a widening net

Rincker was not the only new arrest. William Lee Spartacus Falkner of Washington state was also charged with conspiracy to commit murder, bringing the total number of publicly identified federal defendants to seven, Fox News reported. Falkner allegedly joined a Telegram drone operations chat on June 7 and discussed obtaining drones capable of carrying heavy explosive payloads, anti-jamming measures, and fiber optic controls.

After news of the initial arrests broke, Falkner allegedly texted a co-conspirator: "Work trip is canceled. My boss got picked up."

Investigators believe as many as 19 additional individuals may be involved, identified through the encrypted chat communications. Newsmax reported that the Justice Department has signaled the investigation remains active, with additional charges or arrests possible.

The disclosure of the drone-attack plot before all arrests were completed previously generated friction between agencies. But the pace of new charges suggests investigators are methodically working through the network.

Law enforcement says disruption came first

U.S. Attorney R. Matthew Price of the Western District of Missouri framed the case as a model of proactive law enforcement:

"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."

FBI Deputy Director Chris Raia offered a blunter assessment of the ongoing arrest strategy. "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."

Acting Attorney General Todd Blanche echoed that posture: "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 itself has been the site of multiple security incidents in recent months, placing extraordinary pressure on the Secret Service and federal law enforcement to maintain a credible deterrent.

What remains unanswered

The case still has significant gaps. The current legal status of Alvarez, whether he is in custody or at large, was not addressed in the latest filings described by KMBC. The identities and statuses of the remaining members of the alleged 20-person network are unknown publicly. The specific federal statutes underlying the conspiracy to commit murder charges have not been cited in available reporting.

Nor is it clear how far the World Cup discussion progressed beyond talk. The affidavit language, "I believe that Rincker is sharing Alvarez's idea", describes an investigator's interpretation of encrypted messages, not a fully formed operational plan. But in a case where the White House plot reached the stage of drone procurement, cash transfers, and weapons stockpiling, even preliminary targeting discussions deserve serious weight.

The forensic trail from related White House security incidents continues to grow. 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. As many as 19 more suspects identified. A disrupted attack on the White House and a discussed follow-up targeting the World Cup in Kansas City. The conspiracy, as alleged, was not the work of a lone actor scribbling fantasies in a notebook. It involved cash, equipment, encrypted coordination, and operational planning across multiple states.

A mother's phone call to police may have stopped the worst of it. The question now is whether the full network has been identified, and whether Kansas City is ready for what comes next on July 3.
