The LA County Coroner’s office has concluded its investigation into the mysterious death of pop superstar Michael Jackson. They now know what killed the singer…they just aren’t telling anyone.

The police department for Los Angeles has put a hold on the case for security purposes, which means the results of Michael Jackson’s autopsy can’t be fully disclosed as of yet. Before Jackson’s human remains can be properly put to rest at Forest Lawn Cemetery, the death certificate must be changed to reflect the correct cause of death and a burial permit must be obtained. Since details cannot yet be made public, this, too, might be on hold until more is revealed in the case.

What’s the purpose of withholding the information? Look for the police to make an arrest soon, or otherwise further their criminal investigation into the case.
