OK, so is this all made up by the media then?
"It may never be known if it was his obsession with Satanism which motivated him to murder Jodi, but her gruesome death bore the hallmarks of a ritual killing.
Mitchell's jotters from Dalkeith's St David's High School were daubed with Satanic slogans and he wrote a school essay with worrying references to the devil.
His English book, shown to the court, had the numbers 666 and "Satan lives" on the cover.
"I have tasted the devil's green blood" was also scrawled on the back.
Several other jotters were shown which contained slogans such as: "Evil is the way", "Depression is only a stage in my life, so f*** off and stay out my mind" and "the finest day I ever had was when tomorrow never came" - a quotation from late Nirvana singer Cobain.
The handwritten essay, questioning the existence of God, had been submitted in January 2003 in place of a short story, which had been requested.
The essay contained passages such as: "If you ask me, god is just a futile excuse at most for a bunch of fools to go around annoying others who want nothing to do with him.
"Are these people insane?"
It also read "People like you need Satanic people like me to keep the balance" and "Once you shake hands with the devil you then have truly experienced life".
It was also claimed he said he could imagine himself getting "stoned" and killing someone.
And the trial heard that Mitchell had been in possession of several knives, one of which he used for cutting up blocks of cannabis.
A knife pouch with the initials "[Name removed]" - apparently a reference to Jodi Jones - and the numerals "666" written on it was found in his bedroom".
