Some years later, he left the island and a villa was built on it and thus the mysterious incidents started taking place.
In the 1920s, a Swiss man known as Hans Braun purchased the island and was later found murdered and wrapped up in a rug. His wife was drowned in the sea.
A German man Otto Grunback then purchased the island and died of a heart attack on the island.
The next owner was a pharmaceutical industrialist who lived on the island for some time and was later ended up in a mental asylum of Switzerland where he committed suicide.
