McNair's Mistress/Killer Caught on Video During DUI Stop Two Days Earlier

Just two days before Steve McNair was shot and killed by his 20-year-old girlfriend, Sahal Kazemi, she was stopped for a DUI. The incident was caught in its entirety on camera. McNair was the passenger in the car, a Cadillac Escalade that the former NFL player had bought her for her birthday.

The video was released on Wednesday by police, and in it Kazemi laughs and teases the arresting officer. But she also repeatedly asked to have McNair come to the window of the police car.

The cop told her, "He's not happy. I told him you wanted to talk to him, and he was more than welcome to come back to the car. He just left in a taxi."

Later she received a call from someone named Steve, and it was assumed that it was McNair, as McNair later bailed her out. The following day, Kazemi reportedly told a friend "My life is a ball of s- - -. I should just end it."

Police say that Kazemi killed McNair as he slept on July 4, upset about his fling with another woman. Days earlier she bought a gun, and according to Nashville police, she carried out the crime with the precision of an executioner - going to his condo, and then shooting him twice in the head and twice in the chest.

She then tried to position herself so that she would slump into his lap as she shot herself. The murder weapon was found near her body.

Cops believe that in her last days, Kazemi's life was spinning out of control. On June 29 she told a friend her life was "all screwed up", and her roommate had just left leaving her to pay double the rent. To top things off, she found out that McNair - who is married with children - was having an affair with a third woman after she saw her leaving McNair's apartment.
