NEW YORK (CBS) Four days after the shooting death of former NFL star Steve McNair, police delivered their verdict on the Fourth of July killing: it was a murder- suicide. McNair's jilted girlfriend, Sahel Kazemi, 20, shot the former quarterback four times inside his rented Nashville condo, then turned the gun on herself, authorities said.
Now, a CBS News exclusive is raising questions about the police findings, and whether Kazemi was really intent on taking both their lives, as police believe.
In the report by CBS News chief investigative correspondent Armen Keteyian, several people close to Kazemi, who was known as "Jenni," are speaking about the case for the first time.
"I still feel like something is missing, I don't think Jenni ever shot McNair, I don't think Jenni shot herself," Lakresia Polite, a friend of Kazemi's said.VIDEO: Early Show Investigation into McNair murder.

Nashville authorities' theory of the crime casts Kazemi, McNair's 20-year-old girlfriend, as a distraught woman who was in debt, had recently been arrested, and whose life was "spinning out of control," a police spokesperson said in a press conference.
But her former live-in boyfriend of four years, Keith Norfleet, told Keteyian that Kazemi, a Dave & Buster's server, was "outgoing."

She was "positive," and "very happy and upbeat all the time," he said.
Kazemi was arrested for DUI two days before she and McNair were found shot to death. Police say the arrest provoked her to purchase a gun that same day -- the gun which was used to take both their lives about forty-eight hours later.
However, a jailhouse video shows Kazemi was in good spirits despite the DUI arrest.
CBS News also obtained Kazemi's bank statement from the day she died, which shows she had more than $2,500 in her checking account—enough to cover her bills.
"There are a bunch of inconsistencies that would cause me to go back and investigate it further," said Wayne Black, a former police detective and licensed investigator with 36 years of experience.
Tomorrow, Keteyian will reveal that the man who claims to have sold the pistol to Kazemi lied to authorities, raising additional questions about the authorities' investigation of McNair's murder.
