Metro Police Chief Ronal Serpas said the police believe Steve McNair was asleep when Kazemi shot him on the sofa and that she then sat next to him and shot herself.
Gunshot residue was found on one of Kazemi's hands, but police believe she used both hands when shooting McNair.
Serpas also said police believe Kazemi had communicated with friends days before she was ready to 'end it all'. Several things were overwhelming her, including financial problems, Serpas said. Her roommate was moving out, meaning her rent payment was about to increase. She was also making payments on the Escalade she co-owned with McNair.
Serpas said Kazemi had learned McNair was involved with another woman days before the murder and attempted to follow the woman, whom police said they talked to but Serpas did not identify.Police also believe Kazemi purchased the gun in the parking lot of Dave & Busters, where she worked.
