The key question in the case is, who hired Doctor Conrad Murray? but during the past two days, all eyes have been on Katherine Jackson.
Michael Jackson's mother, 83, endured a second day of confrontational questioning from attorneys for AEG Live, the company she and Jackson's children are suing for billions of dollars over the singer's death. She told the court that she watched her son "waste away."
She has appeared confused, tired and irritated on the stand, CNN's Casey Wian reports.
AEG Live, which promoted what was to be Jackson's big comeback concert series, is trying to show there was no way it could have prevented Michael Jackson's drug overdose when even his own family couldn't.
However, the aggressive questioning of Katherine Jackson could be risky for AEG Live. Though they showed inconsistencies in her testimony, the stern treatment of a woman who jurors see needing help getting on and off the witness stand, could backfire.
