I think your right, it sounds like he intended to just shoot her then himself and your also right about the media. I've said it before, we've lost the "investigative" reporters. They used to really want to find out what happened but now you have these plain reporters that put no effort into their stories. Then if there is a gun involved, they just make it sound like it's the gun's fault that the incident happened and leave it at that. I'd want to know what made this guy think the child's mother was so bad that he thought the only thing after fighting for custody for 6 years, was to kill her. Among other things.
