Five men across four states now face life in prison after federal prosecutors charged them with conspiring to detonate explosive drones and deploy snipers against the crowd at UFC Freedom 250, the fight card staged on the White House grounds to celebrate President Trump's 80th birthday.
The tip that unraveled the alleged mass-casualty plot came not from a surveillance program or an intelligence intercept. It came from a mother in Ohio.
On June 10, the mother of 19-year-old Tycen Proper contacted the Danville Police Department and the Knox County Sheriff's Office about her son's "recent conduct," a federal affidavit states. She told investigators that online contacts, people who claimed to be former military members and described themselves as "Christian-based", had drawn her son into increasingly alarming behavior. She had overheard him discussing physical training for "recon" and "hit and run missions," and she believed he was preparing to carry out shootings. FBI Director Kash Patel said authorities first became aware of the threat that same day.
What investigators found after that phone call, as detailed in court filings and the Justice Department's account, describes a plot that was specific, organized, and well along in its preparation.
The five defendants, Proper, 24-year-old Bryan Omar Roa, 32-year-old Michael Alan Thomas, 32-year-old Daniel K. Eskridge, and 31-year-old Abraham Hermosillo Alvarez, allegedly began communicating around March. Prosecutors said the most serious participants eventually migrated onto an encrypted Signal messaging group. The FBI infiltrated that group as the alleged planning accelerated.
The attack concept, as laid out in the charges, had two phases. Small drones packed with explosives would be detonated over the north side of the UFC arena. Snipers would then open fire on the escaping crowd.
Around 4,300 guests attended the UFC event. Roughly 1,200 of them were active-duty members of the U.S. military.
Thomas allegedly organized the group into four operational "tiers." Tier one consisted of fighters on the ground. Tier two included drivers and drone operators. Tier three would supply equipment. Tier four would work as social media influencers, presumably to spread the group's message after the attack.
Thomas did not treat this as casual talk, prosecutors said. In one message, he warned:
"Tier one status is not something to take lightly."
On June 7, Thomas allegedly wrote in the group chat that "$1300 gets us the drones and the charges. Yes we should all pitch in and we need it asap..." He also discussed meeting Roa in Southern California for "marksmen training" and said the group needed to prepare for "gorilla style warfare." When agents searched Thomas' home on June 13, they allegedly recovered a rifle, 30-round extended magazines, 180 rounds of ammunition, and a pistol.
Thomas also made clear, at least in the messages prosecutors attribute to him, that loyalty was expected to be absolute:
"We will try to break them out of jail if we need to."
The FBI believes Alvarez, who allegedly used the name "Shepherd" in the encrypted group, was responsible for organizing and directing the assault on the White House grounds. He allegedly shared proposed launch points, sniper positions, and an escape route leading to a safe zone at an old Nebraska church.
In one message attributed to him, Alvarez laid out the tactical picture with chilling specificity:
"This is the best action I see. Position your teams in the purple dots (counter sniper and drones) Long range (circled area) (great shot) Easy out into the river."
When asked about the type of explosive charges needed, Alvarez's alleged response was blunt: "As many and as deadly as we can get."
He said he already had one drone and was working on obtaining more, prosecutors stated.
Eskridge, also 32, was identified after the FBI examined electronic messages on Proper's phone. He allegedly described one possible target as "big and someone a majority of the country knows." He later outlined what the operation would require: five teams of three people each. Every team would include a sniper, a ground operator acting as support and lookout, and a drone pilot.
In May, Eskridge shared a photograph of tactical equipment including a rifle, helmet, and ballistic vest, prosecutors said.
Proper, the youngest defendant at 19, allegedly spent $3,000 of his high school graduation money on a shotgun, a rifle, and "lots" of ammunition, his father later told investigators. Agents searching the family home found thousands of rounds of ammunition, spent cartridge casings, and tactical clothing.
The federal affidavit paints a picture of a young man drawn into radicalization through online contacts. His mother told investigators that talking with these individuals had caused her son "to lean heavily into his religion," and she believed "those individuals were using religion to manipulate and influence her son."
An earlier affidavit stated that Proper allegedly admitted planning a coordinated assault with others to "jumpstart" a revolution against the U.S. government. The group believed the country was heading in the wrong direction and "needed to be torn down so that it could be rebuilt."
Proper was interviewed at a medical facility on June 11, one day after his mother's call. He had also allegedly identified possible targets, including several members of Congress.
Roa, 24, was arrested in Southern California after agents searched his home and vehicle. Investigators allegedly seized a rifle, handgun, tactical belt, ammunition, a rifle magazine, a two-way radio, and an infrared laser target pointer. Roa's phone contained group messages with Proper, Thomas, and others discussing explosive drones and rooftop snipers, prosecutors said. Agents also found Instagram videos that allegedly showed Roa firing guns.
The five defendants were arrested during a coordinated multi-state operation in Ohio, Missouri, Nebraska, and California. The suspects had allegedly planned to meet in Fredericksburg, Virginia, before traveling to Washington, D.C., for the attack.
Each defendant faces up to life in prison and a $250,000 fine if convicted of conspiracy to commit murder. A separate charge, conspiracy to carry out violence on White House grounds, carries a maximum sentence of five years. The Justice Department said the investigation remains ongoing.
Acting Attorney General Todd Blanche framed the case as a vindication of federal law enforcement's ability to move fast on credible threats:
"The FBI, our law enforcement partners and our U.S. Attorneys did what they do every day to make America Safe through quick response and vigilance in investigating, disrupting, and dismantling this alleged plan before it could be carried out."
Blanche added a warning aimed beyond this case:
"We will take immediate and aggressive action to identify and prosecute those who incite and plan acts of violence."
Secret Service Director Sean Curran noted that threats against the president and other protected officials had risen sharply. He stated plainly where his agency's focus lies:
"Protecting the President of the United States and the White House grounds is priority number one for the U.S. Secret Service."
The charges raise questions the public record has not yet answered. No defense attorneys have been publicly identified for any of the five men. None of the defendants has responded publicly to the allegations. The specific court handling the case and the full list of statutes cited beyond the two named charges have not been disclosed in available filings. And the Justice Department's statement that the investigation is ongoing suggests the government may believe the network extended beyond these five individuals.
It is worth pausing on how this case broke open. Not through a billion-dollar surveillance apparatus. Not through an algorithm. A mother in Ohio noticed her teenage son was buying guns with his graduation money, talking about "recon" missions, and falling under the influence of strangers he met online. She picked up the phone and called local police. Within 24 hours, the FBI was aware. Within days, the alleged plot was dismantled and five men were in custody across four states.
That sequence, a concerned parent, responsive local law enforcement, and a federal agency that moved with speed, is how the system is supposed to function. The fact that it did function, in this case, prevented what prosecutors describe as a planned massacre of thousands of Americans, including the president and more than a thousand active-duty service members.
When vigilance works, it doesn't make headlines for what went wrong. It makes headlines for what didn't happen. And what didn't happen here should keep every American grateful, and every would-be revolutionary on notice.
