Police investigating the shooting death of four-time Pro Bowl NFL quarterback Steve McNair are still attempting to piece together events leading up to his death.

McNair, who was married with four children, was found Saturday with multiple gunshot wounds on a sofa in his living room, while the body of 20-year-old Sahel Kazemi was alongside him, killed by a single gunshot wound – a pistol was discovered near her, police said.

Authorities have not said who was to blame for the killings, but they weren’t looking for any suspects and do not believe McNair’s wife was involved, spokesman Don Aarons said.

Autopsies were conducted Sunday with results expected later in the day.

McNair, 36, and Kazemi had been together just two days earlier, when she was pulled over driving a 2007 Escalade registered to her and McNair.

She was arrested on a DUI charges, and he was allowed to leave in a taxi. An arrest affidavit from Thursday said Kazemi had bloodshot eyes and alcohol on her breath when she was pulled over, but refused a breathalyzer test, saying “she was not drunk, she was high.”

Police said a witness saw McNair arrive at the condo between 1.30 and 2am Saturday and that Kazemi’s vehicle was already there.

The condominium is located within walking distance of an area filled with restaurants and nightspots, a few blocks from the Cumberland River and within view of the Titans’ stadium.

Kazemi’s ex-boyfriend, Keith Norfleet, told The Tennessean newspaper that McNair and Kazemi met at the Dave & Buster’s in Nashville where she worked.

In June, McNair opened a restaurant near the Tennessee State University campus. It was closed Saturday evening, but had become a small memorial, where flowers, candles and notes had been placed outside the door.

McNair led the Titans to the 2000 Super Bowl, which they lost 23-16 to the St. Louis Rams. He was co-MVP of the NFL with Colts quarterback Peyton Manning in 2003. He also played for the Baltimore Ravens before retiring in April 2008.

McNair is survived by his wife Mechelle, and sons Junior, Steven, Tyler and Trenton.
