Thick criminals

Thankfully some criminals are thick! or is it that they are tired? Surely the shoplifter new that his dna would link him to Marie Jamieson's murder. Or was he tired of that mental "being on the run" feeling that surely criminals must experience when they don't get caught... always looking over their shoulder. What a fantastic outcome for an old case.. now all we need to do is get it to court and get the rightful convictions. mmmmmm, I won't hold my breath but I will hope.
