The discovery of the remains of a husband and wife in Newcastle, Co Down has shocked the community.
At this stage police suspect the couple died of carbon monoxide poisoning.
However, a post mortem examination is to be carried out to give an exact cause of death and to establish how long the couple died.
An investigation will also look at gas appliances in the caravan to track down the possible gas leak.
The man and woman were found in the long stay section of the park on the Tullybrannigan Road around 3 pm.
