Somehow, 15 years after he was gunned down on March 9, 1997, the murder of The Notorious B.I.G. remains unsolved. An autopsy report post by TMZ has revealed some new details, though. Of the four bullets that struck the 24-year-old rapper, three were labeled as not fatal according to the report posted earlier (December 7).

The first bullet that struck Wallace hit his left forearm and traveled down to his wrist. Bullet two hit his back, missing all vital organs and exited through his left shoulder. The third bullet hit his outer left thigh and exited through his inner left thigh. However, the fatal bullet was the fourth as it entered through Wallace's body through his right hip and ripped through several vital organs before reaching his left shoulder area.

TMZ is also reporting that the bullet "perforated Wallace's colon, liver, heart and the upper lobe of his left lung."
