A man who posted a graphic video on YouTube in which he claimed to be holding his father’s severed head was charged with murder and abuse of a corpse early Wednesday after his father’s body was found in a Pennsylvania home, the police said.

Lt. Stephen Forman, a detective with the Middletown Township Police Department, said the man, Justin Mohn, was arrested Tuesday night. The police also confirmed that it was Mr. Mohn in the YouTube video, in which he promoted conspiratorial and anti-government views and briefly showed what he claimed was his father’s head wrapped in plastic.

The video, which has since been removed, appeared to have been filmed during the daytime and was online for about five hours, Lieutenant Forman said. He added that it had received just over 5,000 views. During the time the video was available Mr. Mohn’s subscriber count increased to eight from four, the detective said.

“From the way he was talking, you’d think he had a whole militia with thousands or hundreds of thousands of people,” Lieutenant Forman said, referring to Mr. Mohn’s small following on YouTube.

Mr. Mohn was arrested in Fort Indiantown Gap, more than 110 miles from the scene of the crime, said Chief Joseph Bartorilla of the Middletown Township Police Department. He was being held without bail, according to Lieutenant Forman.

The police said that Mr. Mohn’s mother, had called them around 7 p.m. on Tuesday and reported finding her husband dead. The police said the man was found in the bathroom of the home, in Levittown, about 20 miles northeast of Philadelphia.
