One of the best rappers ever. He was apart of Eminem's rap band called D12, he was also great friends with Eminem, he played as Lil Tic in the movie 8 Mile and was Eminems best man on his 2nd marriage. He was shot dead in Detroit on April 11 2006 at 4 in the morning. R.I.P Proof we all miss you.
R.I.P Proof, you were a great rapper, and a great man. You may be dead but you still live on through our hearts and minds. You wont be forgotten. Say hi to Biggie, Pac, Big L, and Bugz for me.
