Aubrey-Lynn Showitz was a teenage girl who was murdered by Earl Hanford with her mother, father, and older sister in a region of the Florida Everglades called the "Devil's Keep." The family was from a small town in Ohio, on vacation in Florida. The killer operated an airboat and offered to give them a tour of the Everglades. Instead, he shot the father, then raped the mother and two daughters. Afterwards he tied concrete blocks to their ankles and drowned them in the deeper water of Devil's Keep. He videotaped the rape and murders, then sent the tape to the FBI.
