8:59 AM PT -- The Broward County Coroner has now confirmed Samman passed away at 7:20 AM on Wednesday.
As for cause of death, the coroner told us, "It would be hard to suggest anything other than drugs" based on the conditions in which Samman and Kirkingburg were found.
An autopsy is scheduled -- but there could be delays due to the hurricane in the region.
