DOYLESTOWN, Pa. (KYW Newsradio) — The Levittown man accused of killing his father, cutting off his head, then showing it in a YouTube video doesn’t deny the act. Prosecutors in his murder trial showed jailhouse letters where he said he was trying to start a revolution.
Justin Mohn, 33, doesn’t deny killing his 68-year-old father, Michael Mohn in January of 2024.
As Mohn held his father’s severed head up in a YouTube video shortly after the murder, he accused his father of treason because he was a federal employee with the Army Corps of Engineers.
Mohn was taken into custody on a Pennsylvania National Guard base in Fort Indiantown Gap and charged with first degree murder and terrorism, among other offenses. While in county jail, his mail has been monitored. On the second day of his murder trial Tuesday, prosecutors showed some of nearly 2,000 letters he has sent or received.
One was an apology to the general in charge of the National Guard base for sneaking on the base with a gun. Mohn said he had hoped to give a speech to gain support for overthrowing the government before he was swarmed by military police.
In other letters, Mohn wrote about holding his father’s head up in a video — in what he called “Taliban style” — and said he believed many would see him as a hero for killing and “beheading a federal traitor parasite.” Mohn wrote that killed his father because he was trying to make a citizen’s arrest for treason, but his father resisted.
Prosecutors said his father was unsuspecting and vulnerable, using the bathroom when he was shot in the head.
Medical Examiner Dr. Ian Hood testified there were no marks on Mohn’s father’s body indicating a struggle, nor were there any wounds or other evidence on his hands that would show he tried to defend himself from the shot. But Hood said it was impossible to say for certain if he’d seen the gun.
In letters to right-wing talk personalities Alex Jones and Tucker Carlson, Mohn wrote, “My dad also said I was just like Donald Trump.” Prosecutors said he also wrote letters to podcast host Joe Rogan, the Russian embassy, the U.S. Department of State and President Trump.
Mohn’s lawyers pointed out he had no followers, and was ill-prepared for war, armed only with a handgun, animal crackers, and beef jerky.
