Groundbreaking rapper Ricky Dunigan, who rhymed under the name Lord Infamous, passed away on Friday night at his mother’s home in Memphis. He was 40 years old. The cause of death is currently unknown.
Dunigan helped form the Memphis-based rap collective Three 6 Mafia in 1991 alongside DJ Paul (Paul Beauregard) and Juicy J (Jordan Houston). Infamous drifted in and out of the group since its inception, and his most recent recording was a 2013 mixtape as a part of the group Da Mafia 6ix, which consisted of several members of Three 6 Mafia.
“R.I.P. lord infamous,” Juicy J wrote on Twitter on Saturday. Fellow Mafia member Gangsta Boo also tweeted out condolences. “Rest in Peace Lord Infamous please respect the family and dear friends during this tragedy. I will never forget the shows we rocked together . My heart is in pieces.”
Infamous had suffered a heart attack and a stroke in 2010, though a statement from Infamous’ publicist indicated that it was unclear whether or not his health issues played into his passing.
