Local news is saying the gun was underneath her and it was a semi-automatic pistol.
Speculation of course is that she may have killed Mac and then took her own life. It was also said on one of the local stations that when she was arrested Thursday night that she admitted to being "high" but not drunk. Her sister stated earlier on a news bulletin that made Bloomberg that Mac had told the girl that he and Mechelle were finalizing divorce in two weeks. The local news also showed pics of Mac and the girl on a boat from a vacation from two months ago.
Still a somber atmosphere around Tennessee, both now in mourning as well as disappointment that the icon and role model that Steve became is now shattered with some poor decisions.
He will surely be missed, as a person, a legacy, and an icon.
God bless the family.
