What that means, basically, is that the cause of his death won't be know until toxicology reports are filed and tissue-sample test results are available. Early signs suggest that the rapper suffered a heart attack, a story backed up by his wife, Icelene Jones, who told reporters that he had been complaining about chest pains.
ODB had a history of drug abuse, and there is speculation that this lead to the failing of his heart.
A funeral will be held in Brooklyn on Thursday.
