Chris Kelly, one-half of the 1990s rap duo Kris Kross, has died, the Fulton County, Ga. medical examiner's office confirms. He was 34.
His cause of death is not yet known. An autopsy is set to be performed early Thursday and further information is expected to be released later that afternoon. According to CBS' Atlanta affiliate, Kelly was found unresponsive in his Atlanta home on Wednesday.
Kelly and his longtime rap partner Chris "Daddy Mac" Smith were discovered in 1990 by a young Jermaine Dupri at an Atlanta mall. Their debut album, Totally Krossed Out, was released in March 1992 and sold four million copies. The CD included the hit single "Jump," which topped the Billboard Hot 100 charts for eight weeks. The music video also sold more than 100,000 copies as a VHS video single.
The duo went on to open for Michael Jackson during his Dangerous World Tour in 1992 and also appeared in his music video for "Jam." Kris Kross also appeared in music videos for Run DMC and TLC, on episodes of A Different World and In Living Color as well as the 1993 film Who's the Man? starring Ed Lover and Doctor Dre.
The group's second album, 1993's Da Bomb, went platinum but couldn't match the success of their debut. 1996's Young, Rich & Dangerous, their third effort, went gold.
Kelly and Smith went solo after their album, but reunited in 2013 for So So Def's 20th Anniversary concert.
