The man accused of beheading his father in their suburban Philadelphia home early this year and posting a video of the severed head online is competent to stand trial, a judge ruled on Thursday.

The decision by Judge Stephen Corr came after a five-hour hearing in which prosecutors and defence lawyers each presented expert witnesses.

The defence expert, Dr John Markey, said he had met Justin Mohn, the man charged in the late January killing, four times for nearly five hours and determined he had a delusional disorder. Markey reviewed letters Mohn had written in which he claimed he was a messiah and a Biblical King David-like figure whom the federal government was persecuting.

Mohn, 32, came to believe his own public defender was an agent of the federal government and working against him as well, and he wrote to Russia’s ambassador to the United States, seeking to strike a deal to give Mohn refuge and apologising to President Vladimir Putin for claiming to be the tsar of Russia, Markey said.

“It’s all delusional,” Markey said.

A forensic psychologist who testified for the prosecution, though, said Mohn was competent.
