Rapper Makado has been found dead in his cell.

The 600 affiliate was behind bars facing a double murder charge. The Chicago rapper was convicted of murdering two women. In 2017, Makado shot and killed a 41-year-old and 32-year-old woman.

Prosecutors said that Makado and an accomplice pulled up behind one of the victims’ cars and approached them with handguns. Both men shot the two mothers and were caught after someone identified the gunmen’s car. According to reports, DNA was later found on the victim’s car and returned as a match to Makado and his accomplice.

The rapper was said to have pleaded not guilty to felony counts.

There have been no official reports on how the drill rapper died in the cell yet. He was one of the leading figures in the 600 rap group that helped push the drill era into its prominence.
