(Editor's note: Today, the FBI announced that it would investigate the murder of Marco McMillian.)

Marco McMillian was a trailblazer, and the pride of the Mississippi Delta.

Just in his 20s, Ebony magazine in 2004 hailed him as on the nation's 30 leaders under the age of 30. And in his 30s, the Mississippi Business Journal hailed him as one of the "Top 40 Leaders under 40."

But at age 34, McMillian's life was mysteriously cut short.
