14-Year Old Drill Rapper Notti Osama Brutally Killed In Harlem [VIDEO]

As Jim Jones will tell you, rapper is a very dangerous profession.

Put the word "drill" in the equation even more so

14-year Ethan Reyes, aka Notti Osama, was an upcoming drill rapper from Yonkers.

He's dead now after being stabbed by 15-year-old  Kelvin Martinez on a Harlem subway platform Saturday at 3 PM.  The knife punctured his liver and he died in the hospital.

Police say he had been in a street fight with Martinez -- who was known to Reyes and was a member of a rival gang -- that spread to the subway platform.

Martinez was initially charged with second-degree murder.  The charge was downgraded to first-degree manslaughter after prosecutors learned that Reyes had cornered Martinez and confronted him with a broomstick and that Martinez was outnumbered by Reyes and his crew.

There is video of the aftermath of the stabbing.

RIP, Notti Osama.
