Roughly two months after her 2013 DUI arrest, Kelly checked into the Pax Rehab House in Altadena, California. A few days later, she died in her sleep on August 15, 2013, at the age of 43. The cause of death wasn't immediately apparent, but police didn't expect foul play. Months later, the Los Angeles coroner's office released a statement saying Kelly's death was the result of an accidental unspecified oral "multiple drug intoxication."

Her estranged husband, Gilliam, blamed her relapse on her boyfriend at the time, claiming that in the two weeks leading up to her death, "she called me 22 times to get away from him." The boyfriend retorted that Kelly's problem was due to years of physical and emotional abuse from Gilliam. We'll never really know the full story, but the end result is the same: a life once filled with potential, ended far too soon.
