"Even more worryingly, he also acquired a fascination with knives. His older brother, Shane, had a knife collection and Mitchell gathered his own array. At a party six weeks before killing Jones, he repeatedly jabbed her in the leg with a knife he had been using to cut up cannabis.
Although she was clearly devoted to Mitchell, Jones was not his only girlfriend. He had also been seeing at least two other girls and may even have been grooming them to see which would make the most suitable victim.
One of them was Kara van Nuil, now 17, who met him at army cadets in 2003. He wooed her with romantic text messages but their relationship ended abruptly after he followed her into the cadet hut one night, crept up on her, put his arm around her neck and placed a knife to her throat. Later he tried to laugh it off but van Nuil had been terrified. One month later he killed Jodi Jones.
Another of Mitchell’s girlfriends was 15-year-old Kimberley Thomson, from Kenmore, Perthshire who he had been seeing for about a year before the murder. They had met while he was on holiday and kept in touch. Her resemblance to Jones was uncanny.
Mitchell had arranged to go and stay with Thomson for a fortnight shortly after school broke up. At some point, he was going to have to break this news to Jones.
Dobbie said: "There is a potential Jodi found out about Luke’s planned holiday with Kimberley that Monday. I think he told her at lunchtime."
So Shane had a collection of knives whereas Luke had a fascination - can you see the prejudice comparison?
There is nothing conclusive in this article, just a lot of maybe's and speculation. But of course they have to justify the conviction, because the evidence presented in court certainly does not!
Why do people think it is so sinister to have a knife collection? Read up on it, it is a hobby in which a lot of people partake! I am not interested in sensationalised news reports!
