(OMAHA, NEBRASKA) — FBI agents arrested a Mexican national in Omaha on June 14, 2026, alleging he orchestrated a mass-casualty attack plot targeting the White House during a scheduled UFC event.

Abraham Hermosillo Alvarez faces federal charges of conspiracy to commit murder and conspiracy to commit violence on White House grounds. The Department of Justice announced the charges on June 16, 2026, two days after the arrest.

According to the FBI, Alvarez planned to strike government officials and attendees at “UFC Freedom 250,” an event scheduled at the White House. Investigators recovered encrypted group chats in which Alvarez and associates discussed using “counter-snipers and drones” to carry out the attack.

Alvarez, who used the alias “Shepherd,” was taken into custody by FBI agents in Omaha. The Department of Homeland Security released a statement on June 18, 2026, confirming the arrest and providing details about his immigration history.

Acting Assistant Secretary Lauren Bis said the suspect should never have been permitted to remain in the United States. Her statement linked Alvarez’s immigration status directly to the alleged plot.

“This illegal alien from Mexico should never have been allowed in our country. He was the ringleader of a failed terror attack targeting UFC Freedom 250 at the White House. He and his co-conspirators now face charges of conspiracy to commit murder and conspiracy to commit violence on White House grounds. He will face justice and swiftly be removed from our country,” Bis said.

DHS confirmed that Alvarez is a Mexican national who entered the United States on a B2 visitor visa. The visa expired in December 2001. He overstayed and remained in the country without legal status.

Approximately thirteen years after his visa expired, Alvarez was granted Deferred Action for Childhood Arrivals, known as DACA, in 2014. DHS noted that the grant occurred during the Obama administration.

The protection was extended to Alvarez despite his having no lawful status since his visitor visa expired more than a decade earlier. His DACA history places him among hundreds of recipients who have faced detention and removal under the current administration’s enforcement push.

U.S. Immigration and Customs Enforcement has lodged a detainer for Alvarez. The detainer was filed following the DOJ’s announcement of federal charges on June 16, 2026. It ensures that ICE will take custody if he is released from criminal proceedings at any stage.

The Omaha suspect’s DACA history has drawn immediate attention from administration officials. The case is being used to highlight perceived risks in the DACA program, which has faced sustained criticism from the current administration.

Under the second Trump administration, DHS has pursued increasingly aggressive enforcement against individuals previously protected under DACA. The American Immigration Council reported on June 15, 2026, that ICE has detained over 260 DACA recipients in the last ten months.

More than 80 DACA recipients have been deported as of February 2026, according to the council’s findings. The numbers reflect a sharp escalation in enforcement against a group that previously received deferred action from removal under prior administrations.

Omaha itself has been a focal point for immigration enforcement activity. In June 2025, a large-scale worksite enforcement operation at Glenn Valley Foods in Omaha led to the detention of over 70 individuals. ICE officials called it the largest such operation in Nebraska under the current administration at the time.

The Alvarez arrest comes amid broader policy shifts affecting DACA recipients and other immigrants with complicated histories. On May 22, 2026, USCIS issued a policy memo reiterating that aliens seeking Adjustment of Status must generally do so through consular processing outside the United States.

The memo further narrows pathways for individuals with complicated immigration histories to resolve their status while remaining in the country. Advocacy groups report that the policy change, combined with increased enforcement, has created heightened anxiety within the DACA community.

The focus on Alvarez’s background has intensified scrutiny of all Dreamers, the common term for DACA recipients. Community organizations report a rise in fear as DHS continues to target DACA holders for detention and deportation, sometimes despite existing regulations.

Federal prosecutors have not announced a trial date for Alvarez. The charges against him and his co-conspirators were unsealed on June 16, 2026. Officials have not identified the co-conspirators referenced in the DHS statement, nor indicated whether additional arrests are expected.

The FBI continues to investigate the scope of the alleged conspiracy. Investigators are examining whether other individuals provided material support or had knowledge of the planned attack on the White House event.

Administration officials have framed the arrest as both a counterterrorism success and an indictment of prior immigration policies. Bis’s statement emphasized the connection between Alvarez’s illegal presence in the country and the alleged terror plot, linking the DACA program to what she described as a failed terror attack.

The case is likely to fuel further debate over the future of the DACA program. The current administration has moved toward more aggressive enforcement against individuals previously protected under the program, and the Alvarez arrest provides officials with a high-profile example to cite.

DHS has not indicated whether the case will lead to new policy directives targeting DACA recipients specifically. The agency’s enforcement priorities, as reflected in the detention and deportation figures reported by the American Immigration Council, point to continued focus on individuals previously shielded from removal.

Court proceedings against Alvarez are expected to begin in federal court. Specific dates have not been made public. ICE’s detainer ensures that immigration enforcement will follow the criminal case regardless of its outcome.

The investigation into the UFC Freedom 250 plot remains active. Officials from DHS and the DOJ have characterized the case as significant, citing both the severity of the planned attack and the suspect’s immigration background as central elements.
