Nineteen year old rapper Speaker Knockerz was found dead in his South Carolina home on March 6th, according to Billboard, who confirmed it with Richland County Coroner's Office.

Speaker Knockerz, born Derek McAllister, was discovered in his garage on March 6.  Foul play is not suspected and an autopsy found no sign of trauma.

A Facebook user claiming to be McAllister's mother, Mesha Wilson, posted about his disappearance several days ago. Earlier today, she posted a Facebook message addressing his passing, thanking supporters for their prayers.
