Four days is a long time to be missing in a place so small. Have to fear the worst, sadly.

British backpacker Amelia Bambridge missing on Cambodian island
A British student who disappeared after a beach party on a Cambodian island has been reported missing.
Amelia Bambridge, 21, who was on her gap year, was last seen in the resort of Koh Rong on Wednesday.
Members of her family, from Worthing, Sussex, flew from the UK to Cambodia where searches of the sea, beaches and jungle have begun.
Ms Bambridge's sister Georgie said the family was in touch with police and trying to stay strong as concerns grew.
Friends reported Amelia's "out-of-character" disappearance after her belongings were found on a beach.
Ryan Harris said "alarm bells started" when she could not be found after the party.
"She always sticks with the group. She never wanders off on her own," he said.
