Hi Sparkle,,,,you can't convict someone because of their attitude though. Yes,,he was like all 24 year olds with a few bob in their pockets,showing off,,,an untouchable,,all the usual traits of a cocky young man,,,but it doesn't make them murderers,,even disregarding some of the things he got up to,,,such as growing " weed " in his garden,,which he actually confessed to the police about.
Doesn't this tell you something about his openness.? He had nothing to hide.
