Two men will be charged in the fatal shooting of Jam Master Jay, a founding member of Run-DMC and New York City hip-hop legend, whose death has remained unsolved for nearly 18 years.

Ronald Washington and Karl Jordan will be arraigned this week in the murder of the pioneering DJ, whose real name was Jason Mizell, the U.S. Attorney’s Office for the Eastern District of New York said on Monday. Jordan will be arraigned on Monday. Washington, 56, is currently serving a federal prison sentence and will be arraigned later this week.

Jordan’s attorney, Michael Hueston, declined comment to NBC News on Monday.

Jam Master Jay ascended to hip-hop royalty during the 1980s as DJ for the groundbreaking Run-DMC. The DJ also opened his own record label, which is best known for discovering rapper 50 Cent in the 1990s.

He was shot dead in his Queens studio on Oct. 30, 2002, at the age of 37, with few clues for police to identify his killer for nearly the last two decades.

Washington was first named as a suspect in Jay’s death in 2007 in federal court documents that alleged Washington was the armed accomplice of a second unidentified gunman. The documents also alleged that Washington was a suspect in the fatal 1995 shooting of Randy Walker, a close associate of the late rapper Tupac Shakur, according to the Associated Press.

In a sworn statement, Washington denied the allegations and claimed hostile detectives had hounded him about the slaying of his “childhood friend” Mizell.
