A 77-year-old Alaska man has agreed to plead guilty to sending over 500 threatening messages to six U.S. Supreme Court justices and unlawfully possessing a firearm as a convicted felon, according to court filings.

Panos Anastasiou faces a felony charge for making threats against the justices from 2023 to 2024, a filing submitted April 10 in U.S. District Court in Alaska shows. He will also plead guilty to being a felon in possession of a firearm stemming from a 1991 conviction.

Under the plea agreement, federal prosecutors plan to recommend a sentence of probation and home confinement, citing Anastasiou’s advanced age, dementia, and a history of throat cancer.

The case comes amid a broader surge in threats against federal judges. It follows the sentencing, just months ago, of a would-be assassin who was arrested with weapons near Justice Brett Kavanaugh’s home with weapons and received roughly eight years in prison.

U.S. District Judge Aaron Christian Peterson is scheduled to hold a plea hearing for Anastasiou on Thursday.

According to a 2024 indictment, Anastasiou in the hundreds of message targeted two of the justices' family members. The communications included violent, racist and homophobic rhetoric, along with explicit threats of assassination, torture and hanging, as well as references to firearm use.

A draft of the plea agreement filed with the court quotes a July 2024 email in which Anastasiou allegedly called for the assassinations of Chief Justice John Roberts, Justices Clarence Thomas and Samuel Alito, and then-President Donald Trump.

“Their assassination is ESSENTIAL for the country and democracy,” the message reportedly stated. “We should make the 6 corrupt [expletives] to be AFRAID very AFRAID to leave their home and fear for their lives everyday.”
