A woman in her late 50s was found deceased and floating in an ocean bay in a temperate region (N31°33′48″, E130°33′55″) surrounded by wave dissipation blocks. The woman’s appearance was orderly, except for her sweater, which was turned up to her face. Her jacket, shoes, and bag were found on a nearby block. The police investigation ascertained that she suffered from depression and had previously contemplated suicide. No suicide note or farewell letters were found. She was last seen alive, by relatives, approximately 6 days earlier.
