Michael Jackson's mother arrives for testimony

Associated Press

LOS ANGELES (AP) — Michael Jackson's mother has arrived at a Los Angeles courtroom to testify in her lawsuit against the promoters of her son's ill-fated comeback concerts.

Katherine Jackson is expected to be the final witness in the plaintiff's case against AEG Live LLC. The Jackson family matriarch is suing the company, claiming it failed to adequately investigate the doctor convicted of giving her son an overdose of anesthetic in 2009.

She has been a courtroom fixture, sitting in the front row of the courtroom as witnesses have described her son's creativity and interactions with AEG Live executives. The trial on Friday concludes its 12th week of testimony.

AEG denies it hired Jackson's doctor or bears any responsibility for the singer's death.
