The mother of rapper Chris Kelly told police that her son became sick after taking drugs, and officials believe an overdose took the Kris Kross rapper's life.
Chris Kelly died Wednesday in Atlanta at the age of 34.
Kelly's mother, Donna Kelly Pratte, 54, and his uncle, Lamar Williams, 52, told Fulton County authorities that Chris Kelly had a history of drug abuse, too.
Paramedics found Kelly, 34, unresponsive on a couch at his Atlanta home and tried administering CPR. Kelly was later pronounced dead at a local hospital.
Authorities have already completed a physical examination of Kelly's body and a toxicology screening was being done to determine cause of death.
It is believed he took heroin and cocaine the night before.
Kriss Kross was introduced to the world in 1992 by music producer and rapper Jermaine Dupri after he discovered the pair at Greenbriar Mall in Atlanta.
Kelly, the "Mac Daddy," performed alongside Chris Smith, a.k.a. "Daddy Mac."
"To the world Chris was Mac Daddy but to me, he was a son I never had," Dupri, his mentor and close confidant, said in a written statement Thursday.
"When I think about it, I spent more time with Chris and Chris than damn near anybody in my whole life, so you can imagine how bad this hurts."
"I will always love you Chris, and I will never let the world forget you, may God bless your soul."
