This case is pretty much telling me that it's slightly more ok to kill on a whim than it is to plan it out. I understand that premeditated murder is grave, but 4½ to 7 years is too easy for any kind of killing! Geez, I think we've all seen cases of involuntary manslaughter with much more severe sentences.
In this particular case, these are the events as far as I've gathered: They got into an argument, she pushed him, he got pissed off, he went and grabbed a "nearby" chin-up bar, beat her to death with it, then tried to make it look like a burglary (unsuccessfully).
Ok, he got into an argument with his wife (who was apparently going to leave him) and obviously there's a lot of tension in the air, his first reaction to being pushed was "FUCK DAT! I'M GONNA BEAT THIS BITCH WITH WHATEVER I CAN GET MY HANDS ON!" ?? Seriously? I mean, hitting a woman is one thing, but for him to go completely bonkers (blind with rage) and kill her is questionable. It really seems to me that there's way more to this story than that evening.
