NASHVILLE, Tenn. -- An emotional Jeff Fisher said his former quarterback Steve McNair was a "great person" who put the Tennessee Titans franchise on the NFL map.

Editor's Note: In the initial reporting of McNair's death Saturday, Channel 4's stories attributed a "fire official." In fact, the confirmation did not come from an official with the fire department.

The Titans coach Monday called the slain quarterback one of the "greatest competitors of all time on the field." Fisher said McNair would want him to tell people McNair was sorry and wasn't perfect.

Fisher was the only coach McNair had for the first 11 years of his NFL career.

McNair's 20-year-old girlfriend bought a gun a couple of days before she was found dead alongside the slain former NFL quarterback, her relative said Monday.

McNair's death is being investigated as a homicide after he was found shot to death multiple times Saturday at a condominium in downtown Nashville.

Farzin Abdi is Kazemi's nephew, but the two were raised together like brother and sister. Abdi said he does not believe Kazemi would have killed the former Tennessee Titans quarterback and herself.

The two were found dead on Saturday in a condominium co-owned by McNair.

Abdi said police told him they are almost sure Kazemi was the shooter, but he said she had no motive.

Nashville police didn't immediately have a reaction to Abdi's comments.

Abdi said Kazemi believed McNair was divorcing his wife and she was preparing to sell her furniture to move in with him.

Wayne Neeley, who co-rented the condo with McNair, found the former Titan on the couch near Kazemi at about 1:30 p.m. on Saturday. Neeley called a friend, who then called police.

The condo where McNair and Kazemi were found dead is located at 105 Lea Avenue.

McNair had been shot twice in the chest and twice in the head, and Kazemi had been shot once in the side of the head. A semi-automatic pistol was recovered from under Kazemi's body.

McNair and Kazemi met at the Dave & Buster's restaurant where she worked as a server and where when his family ate often. The two began dating a few months ago in a relationship that included a vacation with parasailing. Photos posted on TMZ.com showed McNair gazing and smiling at the young Kazemi.

The Metro Police Department has not yet classified Kazemi's death and expect it will be several days before her death is classified.

McNair's wife Mechelle -- the mother of two of his four children -- said she had not heard from her husband in a couple of days. She was at the couple's home Saturday on Bear Road in Green Hills, and police said they do not believe Mechelle McNair was involved.

Abdi said Kazemi believed McNair was divorcing his wife and she was preparing to sell her furniture to move in with him.

Nashville courts had no record of a McNair divorce case, but a 14,000-square-foot home he owned in Nashville is on the market for $3 million.

Police spokesman Don Aaron did not rule out any possibility, although he said they are not actively looking for a suspect. He also said that the time of the deaths is uncertain and that the deaths may not have occurred Saturday.

A source told Channel 4 News that McNair was seen at about 1 a.m. Saturday at a Nashville restaurant.

"There are persons who were around the complex today, visitors, who have been taken to headquarters for questioning, just to see what they know, what they may have seen," Aaron said Saturday. "No one is in custody right now."

A Lincoln Navigator and Cadillac Escalade were towed from the scene. The Escalade was registered to the address of McNair's restaurant and was under both victims' names.

Kazemi Arrested On Thursday Night

Hints of a problem with alcohol surfaced in May 2003 when a Nashville police officer pulled McNair over on suspicion of drunk driving. Police said the quarterback's blood alcohol content was .18 percent -- well over Tennessee's legal limit. He also was charged for having a 9mm weapon with him, but all the charges were later dropped.

McNair was charged with drunken driving in 2007 because he let his brother-in-law drive his pickup truck. Those charges were later dropped when the DUI charge against the brother-in-law was reduced to reckless driving.

And McNair could have been charged again Thursday night when the same officer who arrested him in 2003 stopped a 2007 Cadillac Escalade driven by Kazemi and registered to both her and McNair. Kazemi was arrested on a DUI charge, and he was allowed to leave in a taxi.

The owner of the building where McNair was found is Charles Cardwell Jr., a well-known Metro trustee. Cardwell said Neeley worked or still works at Nashville Sporting Goods as a salesman. Cardwell, who also lived in the building, said the apartment was often vacant but that McNair used it when he came into town.

Neeley had rented the apartment for about four years, said Cardwell, who also said he isn't aware of previous problems at the apartment, which is near McNair's restaurant, Gridiron9.

"Wayne Neeley and Steve are good friends, and he was very upset and shaken for something like this to happen," said Cardwell, who said he had last seen McNair about six weeks ago.

McNair Had Recently Opened New Nashville Restaurant

McNair aided in the revitalization of the Jefferson Street area with the recent opening of Gridiron9, near Tennessee State University. He could be found at the restaurant sweeping floors, eating, serving and talking to people. Restaurant patrons have remarked upon how accessible he was, and many wrote memorial tributes to the athlete Saturday afternoon on the windows of Gridiron9.

Metro Councilwoman Edith Langster called McNair "a role model and a legend."

McNair is usually in Mississippi for the Fourth of July, holding an event for children in Mount Olive. That event was not held this year.

"We played together, hung out together, had conversations about life outside of the game," said Eddie George, McNair's former Titans teammate.

Country music singer Hank Williams Jr., who has recorded the theme for "Monday Night Football" for 21 years, said in a statement released Sunday, "The NFL has lost a great player, and I have lost a great friend. McNair was a good guy, helping many with his humanitarian efforts, and he will be missed."

Gov. Phil Bredesen released a statement Saturday, saying, "Andrea (Conte) and I were very saddened by the news of Steve McNair's death. He has always felt like part of the Nashville family, and he will be sorely missed."

"As good as he was on the football field, that couldn't touch the person," agent Bus Cook said Sunday, still shaken by McNair's death. "I mean it just couldn't."

The public interest in the scene near the apartment caused at least one accident early Saturday evening, in which the back of a vehicle was plowed into by another vehicle.

McNair played in the National Football League for 13 seasons before retiring last year. He was a three-time Pro-Bowler and the 2003 co-MVP of the league.

There will be a public memorial for McNair from 3 p.m. to 6:45 p.m. Thursday at Mount Zion Baptist Church.

A memorial service is scheduled for 7 p.m. at the church. Mount Zion Baptist Church is at 7594 Old Hickory Blvd. in Whites Creek. Funeral arrangements in Mississippi are being finalized for McNair but are expected to be on Saturday in Hattiesburg.
