Newly released 911 calls reveal the moments an Ohio mother sought help for her 19-year-old son after growing alarmed over his guns, ammunition and plans to join a group she believed wanted to "fight the corrupt government" before his arrest in the alleged UFC White House terror plot.

The recordings, obtained by Fox News Digital, offer a look at the concerns that ultimately helped launch an investigation into Tycen Proper, one of seven men accused in an alleged plot targeting UFC Freedom 250 at the White House earlier this month.

In one call, a cousin of Proper's mother, who contacted dispatchers, urged authorities to respond to the family's residence.

"They are having some issues with their son," the caller told dispatch. "She has some concerns with weapons and ammo and a particular mindset that her oldest boy is in right now."

The caller added that Proper's mother had contacted him in a panic.

"I don't think anybody's in immediate danger as in this second," the caller said. "But I know that she has some concerns with weapons and ammo."

📸 Instagram: his mother reported concerns about recent firearms purchases and troubling online communications.

The complaint states that Proper's mother became alarmed after noticing him researching locations near Washington, D.C., while receiving maps and images through text messages and Discord. When she confronted him, Proper allegedly told her members of the group planned to conduct "recon" and "hit-and-run missions."

She later told investigators she interpreted those comments as references to planned shootings.

When deputies arrived at the family's Ohio home on June 10, Proper's father reportedly told investigators his son had recently connected with people online and planned to leave that weekend to meet members of the group.

According to court filings, Proper had spent roughly $3,000 in graduation money on firearms, body armor, ammunition and tactical gear. Family members later voluntarily turned the equipment over to law enforcement.

Federal authorities allege Proper was one of seven men involved in a conspiracy targeting UFC Freedom 250, a June 14 event held on the White House South Lawn.

According to prosecutors, the men connected through online communities before moving conversations to encrypted messaging applications.

Court documents allege the group discussed using explosive-laden drones to trigger panic at the event before positioning shooters to target "high value targets" as attendees fled.

One participant allegedly wrote that "$1300 gets us the drones and the charges," while another encouraged the group to acquire "as many and as deadly as we can get" when discussing drones.

Authorities say members discussed roles that included shooters, drone operators, logistics coordinators and social media influencers.

According to a newly filed federal complaint, authorities identified Falkner through communications uncovered during the investigation. Prosecutors allege Falkner discussed loading explosives onto drones and configuring them for "maximum destructive impact."

Court documents further allege the plan called for explosive-laden drones to attack one side of the event, forcing attendees toward an exit route where co-conspirators armed with sniper rifles and other weapons would be positioned.

One of the suspects allegedly told investigators the goal of the group was to create enough chaos to help bring about the overthrow of the U.S. government.

Prosecutors allege Rincker accepted $1,200 from a co-conspirator to distribute payments connected to the operation and provided a shotgun during an in-person meeting.

During a search of his home and storage unit, investigators recovered firearms, night-vision equipment, a ballistic plate, a thermal imaging scope, a 3D printer, 3D-printed gun parts and other tactical gear, according to court documents.

FBI Director Kash Patel said authorities "stopped cold" the alleged plot before it could be carried out.

Retired FBI agent Jason Pack previously told Fox News Digital the case highlights the importance of family members recognizing warning signs and reporting them to authorities.

"That's how this got stopped," Pack said.

In an interview with Fox News host Will Cain, retired FBI supervisory agent Rob Chadwick praised Proper's mother for contacting authorities despite the personal consequences.

"Thankful for the one mother's courage to come forward and say something, even though it meant the certain arrest of her own son," Chadwick said.
