NASHVILLE, Tenn. -- Tennessee's state medical examiner said Tuesday that investigators have been hesitant to conclude that Steve McNair's girlfriend killed the former NFL star and herself because she didn't appear to have a motive, but that murder-suicide is the most likely scenario.
After the couple was discovered shot to death Saturday, police were quick to label McNair's death a homicide. He had been shot twice in the head and twice in the chest. Sahel Kazemi, 20, was dead from a single gunshot to the head, and under her body was a gun she had purchased less than two days before the killings.
Investigators were waiting on ballistics tests on the weapon before issuing a ruling on Kazemi's death, which state medical examiner Bruce Levy said could come in the next few days. Kazemi's gun purchase, which was revealed Monday, is a strong indication that she was responsible, according to Levy.
"If we had known on Sunday about the gun, I think we would have been very comfortable in ruling murder-suicide," Levy said. "I'll be very surprised now if they rule it isn't."
Levy said an apparent lack of motive by Kazemi has made investigators careful about exploring every possibility, including the unlikely scenario that a third party could have staged the scene. McNair and Kazemi's relationship lacked typical indicators of trouble -- such as concerned family members or police reports and protection orders.
"The thing we always hear is, 'We should have seen this coming,'" he said.
But Kazemi's family has said she was very happy.
"She just had it made, you know, (with) this guy taking care of everything," Kazemi's nephew, Farzin Abdi, said Monday.
Levy said McNair, 36, was shot in each temple and twice in the chest. Three of the shots were taken from a distance, but one of the shots to the temple came from just inches away from his head.
The gun that killed Kazemi was in contact with her head when it discharged, Levy said.
Police spokesman Don Aaron said Monday that McNair wasn't with Kazemi when she bought the semiautomatic pistol that was found at the scene. Police have declined to release the caliber of the gun or the name of the person who sold it to her.
Aaron said the case might not be as neatly resolved as people would like.
"It may be we'll never know exactly why this happened," he said.
Much of what's known publicly about the affair comes from what Kazemi told her family: She was preparing to move in with McNair and believed he was going to divorce his wife, though no court records of divorce proceedings have surfaced.
Then early Thursday, Kazemi was arrested for DUI while driving a Cadillac Escalade that was registered in both of their names. McNair was with her but wasn't charged, and police allowed him to leave the scene. He later bailed out Kazemi.
That night, Kazemi went alone to buy the handgun.
On Friday night and early Saturday morning, McNair was seen with friends in two Nashville bars. A witness said McNair arrived at a condominium he leased sometime between 1:30 and 2:00 a.m. Kazemi's car already was there.
The couple had been dead for hours when McNair's friend, Wayne Neeley, who leased the condo with him, found the bodies at around 1 p.m. Saturday afternoon.
