About This Episode
What is this episode about?
Episode 10 of Below the Surface, titled "Louisa Ioannidis," covers the death of 24-year-old Louisa Ioannidis, who was found floating in Darebin Creek in the Melbourne suburbs on October 11, 2011. Her death was officially ruled an accidental drowning, but her brother, Tass, has spent the fifteen years since pushing Victoria authorities to reopen the case, convinced his sister was murdered.
The episode traces how new evidence surfaced in 2024 and was presented to the Australian public, raising the question of whether it was substantial enough to have Louisa's death reclassified from accidental drowning to homicide. The case sits at the center of a broader pattern the show explores: unusual deaths connected to water, where official rulings and family suspicion remain sharply at odds.
