But, as you say, we need to wait...
Police are saying today that McNair had four gunshot wounds, two to the head and two to the body (I wonder if they are counting exit wounds?). They also say the gun was a semi-automatic which was found underneath the women’s body (and they wouldn’t have moved the body until they had done a bunch of CSI work, explaining why they thought it was a double homicide).
So, if it were staged, the killer would have had to lift up the girl and tuck the gun underneath her. Not sure many gunmen would do that when it would be easy enough to plant it nearby.
Most women act so scared after the first recoil that they stop shooting. They usually don’t keep squeezing the trigger. So, either this chick was comfortable around guns or maybe she was so drugged out that she had no fear.
I think it has become most likely a murder/suicide. It’s total speculation on my part but I think her DUI threatened to draw publicity to their relationship that he didn’t want so he was ready to tell her it was over. She had probably bragged about McNair to her friends and now risked losing her newfound status. We’ll never know for sure, but that’s how I am reading this.
