PITTSBURGH, PA — A Butler man has been sentenced in federal court to four years in prison for threatening to kill President Donald Trump, other federal officials and ICE agents.
Shawn Monper, 33, also will have three years of supervised release upon completing the prison sentence, U.S. Attorney for the Western District of Pennsylvania Troy Rivetti announced.
"The United States Attorney's Office and law enforcement within this district take threats against public servants and law enforcement very seriously," Rivetti said.
"The sentence imposed not only ensures that Monper will be in prison and under judicial supervision for years to come, but also sends a strong message to deter others from making such threats."
In April, Monper pleaded guilty 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 the officials and agents while they were performing their official duties.
In April 2025, the Federal Bureau of Investigation National Threat Operations Section received an emergency disclosure regarding threats posted to YouTube by a user calling himself "Mr. Satan."
The subsequent federal investigation revealed that internet activity associated with "Mr. Satan" corresponded with Monper's residence.
According to Rivetti's office, the investigation also revealed that Monper obtained a firearms permit shortly after President Trump's inauguration in January 2025.
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, Monper posted: "Eventually I'm going to do a mass shooting." A week later, Monper commented: "I have been buying one gun a month since the election, body armor, and ammo."
Investigators determined that Monper posted several threatening statements regarding President Trump, other United States officials, and ICE agents during the period between January 15, 2025, and April 5, 2025, including the two to which Monper specifically pleaded guilty: 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 mid-March, he posted, "ICE are terrorist people, we need to start killing them."
Monper is from Butler County, where Trump survived an assassination attempt while campaigning for the presidency in 2024.
