An Omaha resident was identified as a "key ringleader" in an alleged plot to attack the White House UFC event Sunday with shooters and explosive-laden drones, according to [court documents filed Tuesday](https://nebraskaexaminer.com/2026/06/16/nebraska-man-was-alleged-key-ringleader-in-plot-to-attack-white-house-ufc-fight/).

[Abraham Hermosillo Alvarez was charged in federal court](https://storage.courtlistener.com/recap/gov.uscourts.ned.111792/gov.uscourts.ned.111792.1.1.pdf) with conspiracy to commit murder and conspiracy to commit an offense against the United States. He appeared for an initial hearing Tuesday and is one of at least five people arrested in connection with the plot.

Federal prosecutors allege the planned attack on the [UFC Freedom 250 event](https://www.cbsnews.com/news/fbi-disrupts-alleged-plot-targeting-ufc-event-white-house/) included snipers and explosive drones targeting President Donald Trump, Vice President J.D. Vance, Israeli Prime Minister Benjamin Netanyahu and Elon Musk.

Investigators believe Alvarez operated under the online alias "Shepherd" on TikTok and Signal and was the primary person involved in the planning. The complaint alleges the attack was motivated by "ultra-religious and antigovernment sentiments, specifically citing grievances about government corruption, the handling of the Epstein files, data centers taking up water in communities, and other government actions."

The FBI uncovered the plot after the family of 19-year-old Ohio resident Tycen Proper became alarmed at his firearms purchases and extensive online communications. When Proper told his family he planned to meet with an online group over the weekend, they contacted police. A search executed June 11 on his home and electronic devices revealed communications within a [TikTok group called "Vanguard of the Old"](https://www.cbsnews.com/news/fbi-disrupts-alleged-plot-targeting-ufc-event-white-house/) where the plot was discussed in encrypted messages on Signal.

Messages attributed to "Shepherd" included discussions of sniper placement and escape routes, with an abandoned Methodist church in Western, Nebraska, identified as a "fall back location." FBI agents searched the church on Monday.

Nebraska Gov. Jim Pillen issued a statement praising the investigation. "One of the key ringleaders of this planned attack was identified by the FBI right here in Nebraska," [he said](https://nebraskaexaminer.com/2026/06/16/nebraska-man-was-alleged-key-ringleader-in-plot-to-attack-white-house-ufc-fight/), adding that the state patrol provided significant support in the FBI-led operation.

Alvarez is scheduled to return to court June 24 at 2 p.m. for a detention and preliminary hearing. According to an audio recording of his initial appearance, he intends to retain a private attorney.
