As friends and family mourn the death of Kris Kross star Chris Kelly, authorities in Atlanta say they are investigating the case as a possible drug overdose.
An autopsy is planned for Thursday morning, but police are already looking at drugs as a cause after Kelly, 34, was found unresponsive in his home on Monday, Fulton County police Cpl. Kay Lester told the Atlanta Journal Constitution.
Meanwhile, Kelly’s mother, Donna Kelly Pratte, released a joint statement with Kris Kross’s former record label, So So Def, mourning Kelly’s death.
