The woman forever tied to Steve McNair

Sahel Kazemi -- known as Jenni to her friends -- wore pink shorts and white-metal earrings the night of July 3, 2009, made plans to watch fireworks, and checked to make sure a friend got to her vacation safely. That was Jenni, friends say. Always looking out for the ones she loved. And a few hours later, police say, she took a 9-mm semi-automatic pistol and pumped four bullets into former Tennessee Titans great Steve McNair, then turned the gun on herself.

A year has passed, an investigation has closed, and about 239,000 accounts have been published about the events of July 4, 2009. But nobody, really, is any closer to knowing who Sahel Kazemi was, or how a 20-year-old waitress could, in a matter of seconds, shake an entire community.
