It’s very serious but neither of them were charged?
I think they were extremely lucky.
Anyway, I was thinking about the whole Shane didn't see or hear him discussion while I was out for my chicken curry. It's been a few years since I delved into this case but these are the facts which I will repeat for the benefit of new readers.
Corinne claimed that Luke was home burning the dinner soon after the murder took place but has no way of backing up that claim. Luke's older brother Shane stated that he came home to an empty house and went on the computer to look at porn, keeping an ear for anyone coming in. He was very clear that Luke was not at home.
Luke for his part claimed he went home after hanging about waiting for Jodi. She was supposed to have met him but never turned up. He claims that he went home and started to prepare dinner. He makes no mention of Shane being in the house.
The Mitchell home consisted of a ground floor and an upstairs, it wasn't a big house. If Luke had been at home while Shane was upstairs, wouldn't the latter have heard Luke come in. Wouldn't he have heard him rattling about downstairs, opening cupboards, cooker door etc? Wouldn't he have heard him on the phone?
According to Shane none of this happened, he just wasn't in the house.
In my opinion, this very crucial piece of evidence by Luke Mitchell's brother was key to the prosecution's case and could very well have persuaded the jury.
