Shawn Monper

Introduction

Shawn Monper, 33, of Butler, Pennsylvania, was sentenced on September 1, 2026, to four years of imprisonment followed by three years of supervised release for threatening to assault and murder President Donald J. Trump, other United States officials, and U.S. Immigration and Customs Enforcement agents. United States District Judge W. Scott Hardy imposed the sentence after Monper pleaded guilty in April to two counts of threatening to assault and murder United States officials and federal law enforcement officers with the intent to impede, intimidate, interfere with, and retaliate against them on account of their official duties. The threats were posted to YouTube under the username “Mr Satan” over roughly three months in early 2025, and the FBI traced the account to Monper’s home.

Background Information

On April 8, 2025, the FBI’s National Threat Operations Section received an emergency disclosure regarding threats posted to YouTube by user “Mr Satan.” A subsequent federal investigation confirmed that the internet activity associated with the account corresponded with Monper’s residence in the Western District of Pennsylvania and revealed that Monper had sought and obtained a firearms permit shortly following President Trump’s inauguration. Investigators determined he posted threatening statements regarding the President, other officials, and ICE agents between January 15, 2025, and April 5, 2025. The case was prosecuted by Assistant United States Attorney Brendan J. McKenna, with the investigation conducted by the FBI and the Butler Township Police Department.

The Controversy or Incident That Led to Their Cancellation

Convicted and sentenced. Monper pleaded guilty to two threat counts and accepted responsibility for the remaining charged counts; the judge imposed four years. The statements below are the ones the Justice Department put before the court.

The posts the investigation collected were specific and escalating. In February 2025, Monper commented using his “Mr Satan” account: “I have bought several guns and been stocking up on ammo since Trump got in office.” In March 2025 he wrote: “Eventually im going to do a mass shooting.” One week later: “I have been buying 1 gun a month since the election, body armor, and ammo.” Among the threats between January 15 and April 5, 2025, the announcement catalogs, in February: “Nah, we just need to start killing people, Trump, Elon, all the heads of agencies Trump appointed, and anyone who stands in the way”; in early March, “im going to assassinate him myself,” posted during a YouTube video titled “Live: Trump’s address to Congress”; in mid-March: “ICE are terrorist people, we need to start killing them”; and in early April: “If I see an armed ice agent, I will consider it a domestic terrorist, and an active shooter and open fire on them.” Monper pleaded guilty in April 2026 to two counts and, as part of the plea agreement, accepted responsibility for the other counts he faced. At sentencing, Judge Hardy described his actions as “extremely serious criminal conduct.”

Public Reaction and Consequences

The government’s statements framed the case as a demonstration that anonymous threat accounts do not stay anonymous. United States Attorney Troy Rivetti said the speed with which Monper “was identified, charged, arrested, and detained before he had the opportunity to act on his violent threats demonstrates our joint commitment to protecting those who serve our country,” and that the sentence “sends a strong message to deter others.” FBI Pittsburgh Special Agent in Charge Richard Evanchec said: “Serious offenses will be met with serious consequences. Today’s sentencing proves anyone threatening elected officials and law enforcement will not be able to hide behind a profile name.” Monper’s detention before trial — the announcement confirms he was arrested and detained — means the four-year sentence runs from custody he has already been serving.

Current Status

Monper is serving a four-year federal sentence imposed September 1, 2026, to be followed by three years of supervised release. His guilty plea stands as a federal felony conviction for threatening United States officials and federal law enforcement officers, and his acceptance of responsibility for the remaining counts is part of the plea record. He remains prohibited from possessing firearms — a status that began with his detention and continues through supervised release. No appeal is noted in the Justice Department announcement.

Impact on Their Career/Life

At 33, Monper trades the next four years for the posts he wrote under “Mr Satan,” and emerges into three years of supervised release with a federal threat conviction that permanently bars firearm possession — ending, among other things, the gun accumulation his own posts advertised. The FBI’s emergency-disclosure trail means his online identity is now documented in a federal sentencing record under his legal name. The announcement records no statement from Monper or his counsel.
