This brought to mind the case of Peter Bergmann (an alias). He went to the Northwest of Ireland and took his life by walking into the sea. Before he did so, he made strenuous efforts to ensure his real identity would never be discovered. [cf https://en.wikipedia.org/wiki/Peter_Bergmann_Case]. I also recommend a short Irish documentary called The Last Days of Peter Bergmann [https://vimeo.com/166977498]
