The last song Proof recorded was with Detroit Horrorcore rap group Twiztid for their album Independent's Day called "How I Live". The track was recorded just weeks before his untimely death and on the night Proof was killed he was finalizing a deal to go on tour with the group. The tour and collaboration were a means by Proof to unite Detroit's rap scene.
Proof was shot in the head inside a small bar in a strip of businesses along Eight Mile on February 11, 2006, at about 4:30 A.M.(CST). Proof was dead on arrival at St. John Conner Creek, an outpatient treatment facility.
