What is this episode about?
The episode "Casefile Extra: Elena Milagro Hoyos" from Casefile covers the case of Elena Milagro Hoyos, a 20-year-old newlywed diagnosed with tuberculosis in the spring of 1930. Seeking treatment, her family brought her to the Marine Hospital in Key West, Florida.
There, the Hoyos family encountered a German-born scientist named Carl Tanzler, who claimed he alone could save Elena from certain death. His promise gave the family hope, but it masked disturbing intentions regarding the lengths he was willing to go to in order to preserve Elena's life, laying the groundwork for a case that would become one of the era's most unsettling true stories.
