Former NFL quarterback McNair killed

(CNN) - Former NFL quarterback Steve McNair and a woman were killed in a shooting at a Nashville, Tennessee, condominium, authorities said Saturday.

Police said they found McNair, 36, and a woman identified as Sahel Kazemi shot to death in the residence Saturday after receiving a phone call about an injured person. McNair was shot multiple times, including once to the head, and Kazemi sustained one gunshot wound.

Asked whether the shooting was a murder-suicide, Don Aaron, spokesman for the Nashville Metropolitan Police Department, said investigators have not classified the incident yet. He said investigators have not ruled out anything, but added they were not "actively looking at suspects" Saturday night.

The bodies were found just two days after Kazemi was pulled over in a Cadillac Escalade, registered to her and McNair, and charged with a DUI, Aaron said.

McNair was in the vehicle at the time.

A law enforcement source close to the investigation said the woman is McNair's girlfriend and that the residence is her condominium in downtown Nashville.

Witnesses said he was a frequent visitor there.

Police could not provide details as to the circumstances of the shooting.

McNair's brother, Fred, also confirmed the death but had no immediate details.

McNair spent 13 seasons in the NFL - the majority with the Tennessee Titans - before announcing his retirement in April 2008. He spent his last two seasons with Baltimore Ravens.
