As it was, the investigation stalled due to police errors and possible misconduct and the rap music industry code of silence. The leading theory is that Christopher Wallace, known as The Notorious B.I.G., was behind the killing of Tupac and that his later death by gunfire was in retribution. Like Tupac, Notorious B.I.G.'s death is unsolved.
Years back I read about one event, that to me is telling.
A salient point of Mr. Tupac’s life was taking a gunned-down friend’s daughter to the prom, and yes I believe it to be a factual event documented before his death.
Not the usual postmortem say nice things story.
He heard that the girl’s prom date dumped her, he stopped by the house and offered to be her escort...
To the prom they went to the surprise of many.
Seeing this and reading around, it appears there was a lot more to this artist than his gang connections.
