Okay, that would explain a Scott Peterson (maybe) but not someone who was going to off himself anyway. He could have done that without killing the wife and kid. He was just a vengeful sick pos who wanted to hurt his poor wife by taking from her what mattered most. When this guy pulled the trigger, I'm sure he found himself in a worse predicament than having to pay child support.
Oops... meant to write "without killing the kid" not "wife and kid".
I agree.
