Up-and-coming rhymer Speaker Knockerz was reportedly found dead in his home on Thursday (March 6). He was 19 years old.

According to WIS-TV, the Columbia, S.C., native was discovered in his garage. No foul play is suspected. An autopsy conducted by the Richland County Coroner’s Office on Friday (March 7) revealed no signs of trauma. Final results are pending until a toxicology report and other tests are done.

Speaker Knockerz, real name Derek McAllister, was a rising rapper whose videos on YouTube rack up between 200,000 to 3 million views. His most popular video 'Lonely,' features the rapper reflecting on his come-up and his goals to become the top rapper in the game.

Friend and collaborator Zack Dillan, who directed many of Knockerz's videos, was among the mourners who expressed their grief on Twitter.

"rip my bro speaker knockerz man fr f--- all this rap shit that was my n---- ill remember every laugh we ever had," he tweeted.

Speaker Knockerz joins a mournful list of rappers who have died way too soon. Last year, Meek Mill protege Lil Snupe was shot and killed in Louisiana. T.I.'s protege Doe B was slain in Alabama and New Jersey rapper E-9 was murdered two days before New Years' Eve.

We want to send our condolences to the family and friends of Speaker Knockerz. May he rest in eternal peace.
