Katie Walker, a mother reported missing in Australia, is believed by police to have walked into the ocean near Bondi, though her father says he has found evidence suggesting she had in fact been planning to return home to the UK. He believes new details uncovered in her apartment cast doubt on the police account and raise fresh questions about the circumstances surrounding her disappearance.

According to her father, Walker lost around $200,000 before she vanished, and he fears a mystery man connected to her may be "hiding" her or have knowledge of her whereabouts. The full details of the case, including what was found in her flat and the identity of the man in question, were not available in the provided article text.
