Steve McNair Death Probe Questioned

Story here. Excerpt:

On July 8, Nashville Police Chief Ronal Serpas told reporters, "We do believe, no questions, that she killed Mr. McNair and then killed herself."

Police announced the ruling after what they called "nearly four days of intensive investigation."

But now those closest to Kazemi -- speaking for the first time -- say they find that ruling impossible to believe.

"I don't think Jenny shot Steve McNair. I don't think jenny shot herself," Lakresia Polite, who was a friend of Kazemi's, told CBS News.

...

Azadeh Kazemi, Jenny's sister, told us, "She wasn't angry enough to do something like that. ... She wouldn't have hurt anyone."

"(She was) very positive ... happy and upbeat all the time," former Kazemi boyfriend Keith Norfleet, observed to CBS News.

Police, however, say Kazemi simply lost it in the last week of her life -- stressed out over mounting bills and her relationship with McNair.

In the July 8 news conference, Serpas said, "She had become very distraught ... unraveling ... messed up ... She was spinning out of control."
