In this episode of Crime Bit with Danelle Hallan, we examine the 2019 disappearance of 18-year-old backpacker Theo Hayez in Byron Bay. After a night out, he was asked to leave a bar and was later seen on CCTV heading toward the beach as his phone data showed a short, unusual route.

With no confirmed sightings after that, investigators weighed accident theories against possible third-party involvement. It shows how fast a case can stall when the digital trail ends and no witnesses come forward.
