I was personally surprised he was found guilty at all. I think it likely had something to do with the likely fake witnesses that said he had hired acting coaches to help him act like he was sad and crying during the trial.
I was also surprised as to just how long the trial lasted. This was not that complex of a case but it lasted for months on end. In the US even the most complex cases do not last more then a few weeks.
It was so apparent that he was faking the crying. The judge even stated at the end that he seemed more worried with his statements then his actual emotion of what he had done.
The bathroom had no window. Where was the robber going to go? He didn't even look at the bed to see where his girlfriend was before he started blasting away at a locked bathroom door?
Dude deserves the 15 year max for culpable homicide but will most likely get nothing.
