Steve McNair's Mistress -- The DUI
Sahel Kazemi was busted for DUI two days before she murdered Steve McNair and then committed suicide -- and cops just released dashcam footage of the incident.
Sahel was initially pulled over for speeding on July 2, then forced to take field sobriety tests -- which she failed. Cops allowed Steve and another man in the Escalade to leave in a taxi -- but Steve showed up at the jail later on to bail out Sahel.
The DUI is one of a handful of circumstances -- including Sahel's belief Steve had another lover -- that cops believe led to the shootings.
