A Mother Called the FBI About Her Own Son. It Stopped an Attack on Trump's White House Event.

The break in one of the most serious domestic plots federal prosecutors have charged this year did not come from a wiretap, an informant, or a surveillance drone. It came from a phone call placed by the mother of a 19-year-old in Danville, Ohio, who was worried about what her son had gotten into online.

That call, according to a federal criminal complaint unsealed this week, set in motion a multi-state FBI operation that prosecutors say headed off a planned attack on the UFC Freedom 250 event held on the White House South Lawn on June 14. Five men now face federal charges in the case. Investigators allege the group planned to fly explosive-laden drones into buildings near the event to force a panicked evacuation, then position shooters to fire on the fleeing crowd and on what the complaint calls “high value targets” — including government officials in attendance.

None of the five has been convicted, and the allegations come from a charging document, not a trial record. But the outline laid out by the Justice Department describes an attack aimed squarely at a marquee event the president had personally championed: a championship fight card staged on the South Lawn to mark Trump’s 80th birthday and Flag Day. The fight went ahead without incident — Justin Gaethje stopped Ilia Topuria to take the lightweight title — because, the government says, the FBI had already learned of the threat and moved to disrupt it days earlier.

What prosecutors say the plotters planned

The complaint, filed in the Southern District of Ohio, describes a two-wave plan. In the first wave, the group allegedly intended to use small drones carrying explosive charges to strike buildings in the vicinity of the event, with the goal of triggering a mass evacuation of attendees toward the south. In the second wave, members were to “act as snipers and additional shooters,” according to the filing, opening fire on fight attendees and senior officials as they fled the blasts.

Prosecutors say the conspirators discussed pooling roughly $1,300 to buy the drones and the explosive material — described in the documents as “drones and charges.” Some of those involved allegedly traveled to Fredericksburg, Virginia, on June 12 or 13, two days before the event, as the plan moved from online discussion toward execution.

The charges vary by defendant. All five are charged with conspiracy to commit an offense against the United States, and the case has been framed by the department as a conspiracy to murder government officials. Tycen C. Proper, the 19-year-old whose mother first alerted investigators, faces four counts, including attempted murder of a federal officer. The severity of those counts reflects the government’s contention that the plan was not idle online venting but an operational plot with a target, a method, and a date.

How investigators got onto the plot

The path to the arrests began, the complaint says, with concern inside Proper’s own family. His mother told investigators that her son had recently begun interacting with an online group made up of people who “claimed to be ex-military and Christian-based” and who “expressed ultra-religious and anti-government sentiments.” She contacted authorities because of his behavior. CNN reported that his parents referred him to police.

According to the filing, Proper began communicating in March with others through a TikTok group called “Vanguard of the Old,” whose members said they wanted to protect the country and believed the nation was headed in the wrong direction. The conversations later migrated to the encrypted messaging app Signal, where prosecutors say the group planned the attack. Investigators say law enforcement learned of the threat several days before the June 14 card — early enough to begin building a case and, the government argues, to keep the plot from reaching the South Lawn.

The five charged span four states. Alongside Proper, of Danville, Ohio, the Justice Department named Bryan Omar Roa, 24, of Calimesa, California; Michael Alan Thomas, 32, of Pinon Hills, California; Daniel K. Eskridge, 32, of Kidder, Missouri; and Abraham Hermosillo Alvarez, 31, of Omaha, Nebraska. The geographic spread is part of why prosecutors have described the takedown as a multi-state operation rather than a single local arrest.

A foiled plot, then a public dispute

The case became public on Tuesday when FBI Director Kash Patel announced the arrests. “And thanks to the rapid action of the FBI, our partners, and the Department of Justice in a multi-state operation, multiple individuals are now in custody and allegedly planned attacks were stopped cold,” Patel said. He framed the disruption as proof of the bureau’s posture around major public gatherings: “We are built to detect, respond to, and bring to justice those who threaten the lives of American citizens — particularly during large gatherings like the historic UFC 250 fight.”

Patel’s announcement also opened a rare public rift inside the government’s own security apparatus. According to NBC News, Secret Service officials were angered that the FBI director had publicized details of a largely sealed, ongoing investigation; sources told the outlet that court records were still under seal and that roughly 10 additional suspects had not yet been arrested when Patel posted about the case. The frustration was not over whether the plot was real — the unsealed complaint lays out the government’s evidence — but over the timing of a public statement that some investigators feared could complicate the broader probe.

That tension is its own piece of news. It signals that the investigation is not finished with the five men already charged, and that federal agencies are still working through a wider set of people connected to the online group. It also underscores how unusual the target was: a sporting event on the grounds of the White House, ringed by the same overlapping layers of Secret Service, FBI, and local police that guard the complex every day.

What happens next

The court process has already begun. Proper waived his right to a detention hearing that had been scheduled for June 17 before a federal magistrate judge in Columbus, agreeing to remain in custody while his case proceeds. He is due back for a preliminary hearing on June 29, when prosecutors will be required to show probable cause to continue the case. The other defendants face their own initial appearances and detention decisions in the districts where they were arrested.

The episode lands against a backdrop of repeated security scares around the president and his events. In May, the Secret Service’s fatal shooting of an armed man at a White House perimeter checkpoint underscored how often outer barriers are tested. Weeks earlier, an armed man breached the White House Correspondents’ Dinner checkpoint and the president was evacuated. Those incidents, and now an alleged drone-and-sniper plot aimed at a South Lawn spectacle, arrive as the agencies responsible for protecting the complex have spent months under financial strain from a prolonged budget standoff that left Secret Service and TSA pay in doubt.

For now, the central facts the government has put on the record are narrow and serious: a planned attack on a White House event, five men in custody, a wider investigation still open, and a case that exists because someone close to one of the accused decided to make a call. What the complaint alleges still has to be proven in court. But the plan it describes — explosives to scatter a crowd, gunfire to cut it down — is the kind of threat that, had it succeeded, would have been measured in lives rather than charges.
