Justin Mohn — the Bucks County, Pennsylvania, man accused of fatally shooting and then beheading his father and posting a video with the gruesome results of his crime on YouTube — was sentenced to life in prison without the possibility of parole on Friday.

Following a four-day bench trial, a Bucks County judge found Mohn guilty of first-degree and second-degree murder, among other charges. On each murder count, the judge sentenced Mohn to life without the possibility of parole. The other counts total a maximum sentence of up to 40 years. All counts are to run consecutively. The judge also granted a no-contact order for the immediate Mohn family.

The 33-year-old Mohn, of Levittown, took the stand in the trial and claimed he was trying to "perform a citizen's arrest" on his father, Michael Mohn, for "treason" before resorting to violence in the Jan. 30, 2024, homicide.

"It was a very difficult case. These facts are horrendous for everybody. The key here, the key takeaway, is that Justin is still alive. We were able to prevent a death penalty from being imposed," Steven Jones, Mohn's defense attorney, said.

Michael Mohn, 68, had been an engineer in the geoenvironmental section of the U.S. Army Corps of Engineers in Philadelphia.  During impact statements read by his wife and two other children on Friday, it was revealed that Michael Mohn went back to work part-time with the U.S. Army Corps of Engineers after his retirement.

"Our thoughts are with Mike Mohn's family. They have endured the unimaginable," Bucks County District Attorney Jennifer Schorn said.

The 14-minute YouTube video was up for several hours before being removed. Justin Mohn was arrested later that day after hopping a fence at Fort Indiantown Gap, where the Pennsylvania National Guard operates.

"We should never forget that is what this defendant Justin Moan did and that is who he really is. That depravity we don't see too often," Schorn said.

At his verdict and sentencing proceedings Friday, Justin Mohn told Judge Stephen Corr that what happened is "not the outcome I wanted, but that's okay." He also said he should be used for a prisoner swap with Russia.

After taking a brief pause, a legal pad was slid over to Justin Mohn by his lawyer. The 33-year-old then apologized to his family, but called what he did "justice" and said he did not feel guilty.

Denice Mohn, Michael's widow and Justin's mother, clutched a photo of her late husband and quietly sobbed while someone else read her victim impact statement to the courtroom. 

Judge Corr acknowledged Justin Mohn was found competent to stand trial, but also said that does not mean the 33-year-old does not suffer from mental illness.

"Somewhere this went off the rails," the judge told the courtroom. He further went on to say the case was "an indictment on the mental health system."

Denice Mohn took the stand earlier in the week and recounted finding her husband's body in a bathroom before calling 911. Justin Mohn's parents had been providing financial assistance while he looked for a job.

During a competency hearing last year, a defense expert said Justin Mohn wrote a letter to Russia's ambassador to the United States seeking a deal to give him refuge and apologizing to President Vladimir Putin for claiming to be the czar of Russia. A judge ruled that Justin Mohn was competent to stand trial.  

"It was a long case. The verdict that was reached, we respect. Judge Corr is an excellent judge. He was very fair. He was very patient," Jones said.
