Whitney Houston's cause of death could not be determined so far by officials.  Though it has been proven that no wrongdoing was involved in her death, the coroner’s office remains clueless as to how she actually died. 

Since there is no clear evidence leading to the cause of her death, officials are going to continue with their investigation.  For now, reports suggest that more toxicology tests are underway and the cause of death will not be announced until all impending tests have been completed successfully.

Because of this, her death certificate carries “deferred” as the cause of her death.  We will keep you posted with any further developments.
