The police say the post mortem started yesterday on Shawn Warner is so far inconclusive.
Police PRO Frankie Thomas says further forensic testing is scheduled to be carried out.
Shawn died last month in Jolly Harbour after an alleged electrocution.
Meantime, some family members say they are concerned that they are being told that Shawn died of a heart attack.
They did not reveal the source of the information.
