NASHVILLE, Tenn. AP – Investigators were waiting for ballistics tests on a gun recently bought by the girlfriend of slain former NFL star Steve McNair to determine whether the firearm found at the scene killed the two.

Police said Monday that 20-year-old Sahel Kazemi bought the handgun found under her body less than two days before the shooting. They were found dead on the Fourth of July – McNair from two gunshots each to the head and chest, Kazemi from a single shot.
