Despite initial reports, it could take a few weeks to find out what killed Michael Jackson. His brother, Jermaine, confirmed that the King of Pop suffered cardiac arrest; but it is still unclear what led 
to that.
MTV.com is reporting that autopsy on Jackson's body is currently underway in Los Angeles, but the toxicology reports could take a few weeks.
"The likelihood is very slim that we will have any results to release today because of the extensive [tests] that we're going to be performing," Assistant Chief Coroner Ed Winter said at a press conference. "We will be performing toxicology tests and an extensive exam, and it could take up to six to eight weeks before we will have the final results from the onset, from last night."
It does, however, seem that if the cause of death is apparent after Friday's autopsy; then an announcement could come immediately.
