DeShaun Dupree Holton (October 2, 1973 – April 11, 2006), better known by his stage name Proof, was rapper and actor from Detroit, Michigan. During his career, he was a member of the groups Goon Squad, 5 Elementz, Promatic, and most notably, D12. He was a close childhood friend of rapper Eminem, who lived on the same block.
Originally known as Maximum, under the moniker "Proof", Holton first rose to national prominence as a part of the rap group D12, a hip-hop group he was instrumental in forming. Early individual accomplishments include being featured in The Source's "Unsigned Hype" column in 1999 and nearly winning the 1998 Blaze Battle. His first television appearance was in the video for Aaliyah's "Age Ain't Nothing But a Number".
In 2000, Proof toured with Eminem, Dr. Dre, and Snoop Dogg in the Up In Smoke Tour, performing as a hype man for Eminem. He gained further exposure in 2001 with the release of "Devil's Night", D12's debut album on Interscope Records. The following year, Proof collaborated with Dogmatic on "Promatic" and joined Eminem's "Anger Management" tour in support of the release. He appeared in the film "8 Mile" along with Eminem and Xzibit, although the character based on him, Future, was portrayed by Mekhi Phifer. Proof appeared as Lil' Tic, a freestyle rapper who rap battles the lead character, B-Rabbit, played by Eminem. To capitalize on the publicity from the film, Proof released a six-song EP called "Electric Coolaid: Acid Testing". Proof also starred in a cameo role, alongside the rest of D12, in the film "The Longest Yard", appearing as "Basketball Convicts" during the credits.
On April 11, 2006, Proof was shot four times by Mario Etheridge, after an altercation broke out during a game of billiards at the CCC Club on 8 Mile Road in Detroit, Michigan. On April 19, 2006, Proof was buried in the Fellowship Chapel in Detroit to a full house of 2,660, including long time friend Eminem, Royce Da 5'9", D12 and thousands more mourning outside.
