In April 1930, the German-born radiology technologist Carl Tanzler met a Cuban-American tuberculosis patient named Maria Elena Milagro de Hoyos, and soon developed a deep obsession with the beautiful young woman. He believed she was his true love, something that had been revealed to him in a vision he once experienced during his childhood, and he frantically used every possible medical treatment available in an attempt to cure he of the disease. Despite his best efforts, the young woman died of tuberculosis on 25 October 1931. Tanzler, who also went by the name Carl von Cosel, paid for her funeral costs and commissioned the construction of lavish mausoleum in the West Key Cemetery in Florida, which he visited every day for many years. In October 1940, Hoyos' sister decided to visit von Cosel's home after hearing ghastly rumours concerning the theft of her sister's body and discovered he had been keeping her corpse for his own sinister purposes.
