Michael Amir Williams , who was Michael Jackson 's personal assistant, has filed a class-action lawsuit against AEG, the promoter of Jackson's aborted This Is It tour, reports TMZ.com .
Williams alleges that he and many other employees lost a lot of money because This Is It never happened due to AEG negligently employing Dr. Conrad Murray . It was Murray who gave the singer a fatal dose of the powerful anesthetic propofol and was later convicted of involuntary manslaughter.
According to Williams, AEG should never have hired Murray to begin with, but when they did they failed to supervise him.
Williams claims in court papers that AEG already agreed to pay Jackson's staff some $7.5 million for the work they did on the tour, but he's asking for unspecified damages.
