Winter said he believes the results will be announced by Friday or next Monday.

Klein has been uncooperative during the investigation, failing to turn over medical files to officials, TMZ reported.

Jackson died of apparent heart failure at the age of 50 while preparing for a 50-date London comeback tour.
