Jackson 'didn't cause own death'
Michael Jackson's mother says she doesn't believe her son bears any responsibility for his own death.
Katherine Jackson was responding to a question from attorney Marvin Putnam, who represents AEG Live LLC, the promoter of her son's ill-fated "This Is It" concerts at a hearing in Los Angeles.
The 83-year-old Jackson family matriarch is suing AEG Live claiming it failed to properly investigate the doctor, Conrad Murray, who was later convicted of causing her son's death in June 2009.
AEG Live denies it hired the doctor or bears any responsibility for Jackson's death.
