The mother of late pop star Michael Jackson testified Friday in her wrongful death lawsuit that concert promoter AEG Live failed to get her son proper medical attention when he became sick while preparing for a comeback tour in 2009.

Katherine Jackson, 83, broke down when recalling the death of her famous son and later asked to suspend her testimony after growing distressed under cross-examination. It was the first time Jackson had taken the stand in the trial in which she and Michael’s children are suing AEG Live. The “Thriller” singer died at age 50 in June 2009 in Los Angeles from an overdose of surgical anesthetic propofol while preparing for a series of shows in London. The lawsuit alleges that AEG hired Dr. Conrad Murray as his personal physician. Murray was caring for the singer as he rehearsed for the shows and the doctor was convicted of involuntary manslaughter in 2011 for administering the propofol that killed Jackson.
