This episode covers the kidnapping cases of Sharon Wills and Nikki Linus, focusing on how airplane sounds helped investigators track a serial predator known as Mr. Cruel.
Sharon Wills, a 10-year-old girl, used her surroundings to keep track of time while kidnapped. She listened to a radio left on by her captor and noted the sound of planes flying overhead.
Nikki Linus, another victim, also heard planes while being held captive. Her account of hearing between seven and nine planes was crucial for police investigations.
Authorities mapped flight paths around Melbourne, linking the sounds to Tullamarine Airport. This airport is located about 35 to 45 minutes from where Nikki was abducted, aligning with her estimate of time spent in a vehicle.
Investigators focused their search on neighborhoods directly under the flight paths, but the area remained extensive, raising questions about how close they came to finding the right location.
Two girls used airplane sounds to help police track a serial predator in Melbourne.
