And Kazemi had been telling multiple people that her life was all messed up, and she was going to "end it all." She also told people that she thought McNair was involved with another woman.

There was no evidence that anything had been tampered with by Neely or Gaddy.
There was no suicide note, but there is evidence that she was “spinning out of control.”

Mr Norfleet is “no longer a suspect.”

She bought the gun from someone who was going to purchase her car—in the parking lot of Opry Mills.

And McNair was not drugged at the time.

But Chief Serpas did say that they will continue to speak to all people involved as there are still some unanswered questions, however those things do not have any relevance to what the crime scene told them.

the tox screens will be the definitive word on all that. ill be holding my breath til they come back. and if there was any reason for neely to take so long calling the cops, removing paraphernalia or flushing drugs down the toilet would be an obvious reason. i dont want to speculate that it did happen, im just not so sure they have fully proved it didnt happen. until we know his system was clean, there is plenty of room for that kind of wild speculation.
