McNair, 36, a quarterback for the Tennessee Titans most of his career, met Kazemi six months ago at a sports cafe where she was a waitress and his family often ate. She seemed happy and eager to build a life with him, but something went wrong.

...

The man McNair shared the condo with discovered the bodies and called a friend, Robert Gaddy, who arrived and called 911. Serpas said the man didn’t call 911 himself because he was in shock.

Gaddy said Wednesday that what he saw in the condo will haunt him for the rest of his life, but he was glad police made clear that his longtime friend did not suffer.

Kazemi’s family told reporters that the woman was so confident McNair was divorcing his wife of 12 years that she was preparing to sell her furniture and move in with him.

But associate Mike Mu, who has worked with McNair’s charitable association for years, said earlier Wednesday that McNair’s wife, Mechelle McNair, “didn’t know who this girl is.” No records of divorce proceedings have surfaced. The McNairs have four children.

Gaddy defended McNair as a great husband.

“When Mechelle is ready to speak, she will let people know that,” Gaddy said. “We can’t justify anything that people are starting to find out, but the one thing that we can say, that I know for sure, is that Steve loved his family.”

Two days before the shooting, police stopped Kazemi driving a Cadillac Escalade sport utility vehicle that McNair had given her for her birthday in May.

According to an arrest affidavit, Kazemi had bloodshot eyes and alcohol on her breath. She refused a breath test and told an officer “she was not drunk, she was high.” She was charged with DUI. McNair was with her but not charged. He later made her bail.

Police are awaiting toxicology reports on both bodies.

Serpas said that even though both her name and McNair’s were on the Cadillac’s title, she was apparently responsible for making payments. She was also making payments on another car after she couldn’t sell it.

Kazemi had no history of violence, but “on the last several days of her life it’s obvious that she made some very poor decisions,” Serpas said.

Mechelle McNair has not spoken publicly since the shooting. Bishop Joseph W. Walker III of Mount Zion Baptist Church, which the McNairs have attended since moving to Nashville in 1997, said Wednesday that she is doing as well as can be expected.

“Her faith is what’s sustaining her now,” he said. “We haven’t talked about the circumstances of his death. She is processing it in a private way. It’s obviously devastating on so many levels.”

A memorial service is set for Thursday night in Nashville, with the funeral Saturday in his native Mississippi.

The four-time Pro Bowl quarterback was being remembered Wednesday at the stadium where he played much of his career. The Tennessee Titans opened LP Field for fans to watch video highlights of McNair’s 13-year NFL career and look at photos of the quarterback. There was also a book for them to write messages that will be given to the family.

McNair was known as “Air McNair” for his passing prowess at Alcorn State in Mississippi. In 2000, he helped lead the Titans to the Super Bowl, where they ended up a yard short of a touchdown on the last play of the game when they trailed by seven points.

He spent the last two seasons with the Baltimore Ravens before retiring from the NFL last year.

Associated Press Writers Travis Loller, Joe Edwards, Kristin M. Hall and Teresa M. Walker contributed to this report.

Interviews with friends revealed that she was making payments on two cars, her rent was doubling and she suspected the married McNair was having a second affair with another young woman. end it,” Serpas said.

Police earlier had labeled McNair’s death a homicide, but waited for further tests and the revelations about Kazemi’s personal problems before concluding that she pulled the trigger of a 9 mm semiautomatic pistol in a condominium McNair rented with a friend.
