The last words of legendary rapper Tupac Shakur were revealed Friday by the Las Vegas policeman that was the first to arrive on the scene after he was shot in a 1996 drive-by murder.  According to Chris Carroll, who retired earlier this month, he was attempting to find out who shot the rapper when he showed up, but got no cooperation from Tupac as he simply replied to the officer Fuck You.  Carroll noted that another officer rode in the ambulance with Shakur, and continued to question Shakur, but the rapper lost consciousness and never said a word on the way to the hospital.  Once he arrived at the emergency room, he was immediately sedated in preparation for surgery, falling into a coma after the surgery.  Shakur never awoke from the coma, and doctors pulled him off life support several weeks later.  Now, eighteen years later, there has never been an arrest in the case.  When asked why he's coming forward with Shakur's last moments so many years later, Carroll explained that he is retired now and can't be reprimanded.
