In court documents obtained by ET, Williams alleges that he and the crew hired for the This is It tour lost out on wages after Jackson's death.

As Dr. Conrad Murray (who was convicted of involuntary manslaughter in Jackson's case) was reportedly hired and supervised by AEG, the papers go on to ask for unspecified damages from the company.

According to the filings, the plaintiff claims that AEG agreed to pay the crew "up to $7.5 million" for the tour prior to Jackson's passing.
