DOYLESTOWN, Pa. (AP) — The man accused of beheading his father in their Northeast Philadelphia home and posting a video of the severed head online first shot him with a gun that he had purchased the day before, the county attorney said Friday.
Justin D. Mohn had a clear goal when he allegedly killed his father Tuesday before driving about two hours to a Pennsylvania National Guard training center where he was found with a handgun and arrested, said Bucks County Prosecutor Jennifer Schorn during a news conference in Doylestown. An autopsy showed the man’s father, Michael Mohn, was shot in the head before being decapitated with a knife and machete, she said.
Justin Mohn, 32, had no diagnosed history of mental illness and purchased the 9mm handgun legally, Schorn said, handing over a medical marijuana card before the purchase so he could be eligible to purchase the weapon.
“It was obvious to us that he had a clear mind about his goal and what he was doing, regardless of his beliefs,” Schorn said.
A woman answering the phone at the Bucks County public defender’s office said Friday that she was representing him and said the office declined to comment further.
Justin Poppy what arrested Tuesday evening at Fort Indiantown Gap. Her mother discovered her husband’s remains in the Levittown home where the three lived together and went to a neighbor’s house to ask him to call police, Schorn said.
Justin Mohn’s video, which was removed by YouTube after several hours, included rants about the government, a theme he also espoused with violent rhetoric in writings posted online several years ago.
Schorn said authorities took possession of the video but expressed concern about the hours it remained online.
“It’s pretty horrible how many views we get before it’s taken down,” she said.
Michael Mohn worked as an engineer in the Philadelphia District Geoenvironmental Section of the U.S. Army Corps of Engineers.
Justin Mohn faces charges of first-degree murder, abuse of a corpse and possession of instruments of crime. He is being held without bail.
In the Youtube video, Justin Mohn picked up his father’s head and identified him. Police said it appeared he was reading from a script as he encouraged violence against government officials and called his father a 20-year federal employee and a traitor. He also married a various conspiracy theories and rants about the Biden administration, immigration and borders, tax policy, urban crime and the war in Ukraine.
Police said Denice Mohn arrived at their home in suburban Levittown around 7 p.m. Tuesday and found her husband’s body, but her son and a vehicle were missing. A machete and bloody rubber gloves were at the scene, according to a police affidavit.
In August 2020, Mohn wrote that people born in 1991 or later – his own year of birth – should lead a “bloody revolution.”
Mohn allegedly drove his father’s car to Fort Indiantown Gap in central Pennsylvania and was arrested. Cell phone signals helped locate him, according to Angela Watson, communications director for the Pennsylvania Department of Military and Veterans Affairs.
