Opening arguments began Monday in the wrongful death lawsuit filed by Michael Jackson's mother Katherine against the pop star's concert promoter AEG Live.
The trial -- which seeks $40 billion in damages from AEG -- alleges that the company was negligent when it hired Dr. Conrad Murray to oversee Michael Jackson's medical care as the King of Pop prepared for a series of comeback concerts.
In his opening statement, Katherine Jackson's attorney Brian Panish said AEG Live owed it to the late pop star to adequately investigate Murray. "You're going to hear the whole story about what happened in the death of Michael Jackson," he told the courtroom, according to the Associated Press. "His stirring voice, his musical genius, his creativity and his generosity and his huge heart was extinguished forever," Panish added. Katherine Jackson sat in the front row of the courtroom along with Michael's siblings Randy and Rebbie.
