Three 6 Mafia's Lord Infamous Dead at 40

His half-brother and fellow Three 6 Mafia member DJ Paul told THR that Dunigan was visiting his mother when he died. She left for several hours and when she returned, she found him at the kitchen table.

“He passed away in his sleep from a heart attack,” DJ Paul said. “He said he was tired, he wanted to sleep. He sat down at the kitchen table, put his head in his arms to lay down ... to get some sleep."

Paul continued, "He'll be remembered as a legend, everybody knew him as a legend, an icon. This year was going to make our twenty-fourth year rapping together. His music, our music that we made together, was truly before its time."

Lord Infamous, DJ Paul, Juicy J and several other Memphis rappers formed the Backyard Posse in 1993, which later became Three 6 Mafia.

Infamous was reportedly forced to leave the group in 2006 due to violating his contract with Sony. It was around that time that Three 6 Mafia won a Best Original Song Oscar for "Hustle and Flow's" hit song "Hard Out Here for a Pimp."

The group recently reunited to form Da Mafia 6ix and had a show planned next week.

DJ Paul said, "He got a chance to see the group back together like he wanted to and be back in the studio with everybody and be back making music like he always liked to do.”

Juicy J reacted to the news on Twitter, "R.I.P. lord Infamous... Thx you for your prayers , I'm very hurt, can't believe it's true."
