LOS ANGELES -- Michael Jackson's mother tearfully described finding out about her son's death and testified on Friday that she had expressed concerns about his comeback concert schedule to the promoters of the shows.
Katherine Jackson said she called Randy Phillips, the CEO of AEG Live, to voice her view that her son could have done 50 shows -- but not if they were spaced closely together.
"He couldn't do every other night like AEG wanted him to do at first," she said.
Jackson also said she had called her son's manager, Tohme Tohme, to raise concerns about the "This Is It" schedule.
She didn't provide any additional details about the calls.
Jackson was expected to be the final witness called by her attorneys in the negligence lawsuit against AEG Live that has lasted 12 weeks. The defense case is scheduled to begin next week.
Her testimony was stopped in the early afternoon after her lawyer said she only had about three hours of sleep Thursday night and was tired.
The judge spoke with Jackson briefly before dismissing her until Monday.
The Jackson family matriarch sued AEG Live in 2010, claiming it failed to adequately investigate Dr. Conrad Murray, who was later convicted of involuntary manslaughter for giving the singer an overdose of anesthetic in 2009.
