More than two years ago, Kathleen Riethmuller vanished without a trace from the streets of Sydney. Now, detectives have revealed their stunning theory as to why the data scientist went missing.
Police have made a new appeal to find Kathleen Riethmuller, who walked into a backpackers in inner Sydney last October to make a booking she would never fulfil.
Kathleen Riethmuller checked into a backpackers in Woolloomooloo, on October 28, to make a booking for that night. She never returned, and has not been seen since.
