It's been over 15 years since THE NOTORIOUS B.I.G.was gunned down while riding through Los Angeles in the passenger seat of a Chevy Suburban.  But the L.A.P.D. has just now released his autopsy report.

--Here are a few mildly interesting details:

--Biggie was hit FOUR times.  Three of the gunshot wounds were NON-FATAL . . . including one that tagged his SCROTUM.

--The first bullet hit his left forearm . . . the second hit his back and went out his left shoulder . . . and the third one hit his left thigh.  (--That's the one that got his sack.)

--Gunshot #4 was the fatal one.  It entered his right hip . . . ripped through his colon, liver, heart and left lung . . . and came to a rest in his left shoulder area.

--On the report, the coroner listed Biggie as "morbidly obese" . . . and under "other pertinent information," the coroner wrote, quote, "Decedent may be rap singer."  (--You can download .PDFs at TMZ.com.)
