Authorities say former NFL star Steve McNair had a blood-alcohol level twice Tennessee's legal limit for driving when his girlfriend shot him to death.
Tennessee Assistant Medical Examiner Feng Li said Monday that a toxicology report showed a trace amount of marijuana in the body of Sahel Kazemi. Police say the 20-year-old Kazemi shot McNair July 4 in a Nashville condo before killing herself.
Police say McNair was likely asleep when he was shot twice in the head and twice in the chest.

Li said there was no way to tell from the report how long before McNair's death he had been drinking.
Kazemi was arrested for drunken driving in Nashville two days before the shooting. Police video of the arrest showed her telling the officer that she was high.
