Yeah his story doesn't hold up at all, even if what he says is true and he thought that it is an intruder it is still murder. You can't just fire off four shots into a locked bathroom just because you think there is an intruder in there. In saying that I don't think the prosecution should be going for pre-meditated murder, it will be tough to prove that he planned it. After reading the transcripts from the first two days of the bail hearing it sounds like it was more of a spur of the moment thing that he thought he could get away with. I like how he was so worried about security that he had a gun yet he then leaves the balcony doors wide open.
I also still can't believe that he didn't think that the person in the bathroom was his girlfriend. According to his testimony he walked/crawled past his bed after going to the balcony, pretty hard to miss someone not being in bed. Plus, again, who in their right mind wouldn't first call out and ask if it was his girlfriend since he 100% knew that she was in the apartment.
Seriously I wonder if his legs are removed when he goes to prison since they could be used as a weapon.
I have read so many good jokes over the past few days about this situation, it is horrible that an innocent person was murdered but some of the jokes out there are classic.
