Louisa Ioannidis was last seen alive on October 2, 2011, wearing a pink dressing gown as she fled into the night. The following day, her boyfriend reported seeing the same robe floating in a nearby creek, but he did not investigate. This has left her older brother, Tass Stouraitis, perplexed. "You saw Louisa's nightgown and what, you didn't go and approach it and get a closer look at what was going on?" he questioned.

Eight days later, Louisa's body was discovered in Darebin Creek, near Reservoir in Melbourne's north. An autopsy concluded that her death was "consistent with drowning" and the case was closed without being assigned to the homicide squad or undergoing an inquest. Tass was devastated by the findings. "I didn't believe that she just fell in the creek and drowned," he said.

In an effort to uncover the truth about Louisa's death, Tass enlisted the help of podcasters who highlighted inconsistencies in statements from her boyfriend, Joe, and pointed to evidence suggesting Louisa was attempting to escape a volatile relationship. Recently, a report from independent forensic pathologist Professor Johan Duflou has raised new doubts about the cause of Louisa's death. Duflou noted possible bruises on Louisa's neck, stating, "I don't think manual strangulation in this case can be excluded." This report has been submitted to the Coroners Court of Victoria.

Tass and a team of pro bono lawyers submitted the report in July, hoping to overturn the coronial finding and initiate an inquest. "In the hope," Tass said, "that if Louisa was met with foul play, they can get to the bottom of it."

On the day Louisa disappeared, she had a violent altercation with Joe. A neighbor, Cazz, overheard Louisa pleading, "Please Joe, don't hurt me. Stop," before hearing a door slam. Later that evening, Louisa was seen with blood in her hair, asking to borrow a neighbor's phone to call Joe. Joe claimed he had broken up with her and stated that he saw her running towards the creek but did not pursue her.

The podcasters, Julia Robson and Clare McGrath, became intrigued by Joe's account. They conducted an experiment to see if a person in a pink dressing gown could be seen from a distance in the dark. McGrath, positioned 370 meters away, could not identify Robson until she was much closer. This raised questions about Joe's visibility of Louisa that night.

Further investigation revealed discrepancies in the police report regarding the creek's depth, which was recorded at 40 centimeters. Experts noted that drowning can occur in shallow water, but Robson and McGrath questioned how Louisa could have drowned if she was conscious.

Dr. Vince Hurley, a retired detective inspector, reviewed the police investigation and criticized its thoroughness. He suggested that Louisa may have fallen victim to social profiling due to her low socio-economic background. Hurley pointed out that there was no evidence linking Joe to Louisa's death, but he raised concerns about the lack of follow-up on Joe's claims of chasing Louisa and the absence of inquiries regarding a suspicious white van seen near Louisa's flat shortly after her disappearance.

Louisa's life was marked by trauma, including a difficult childhood and a tumultuous relationship with Joe. Her brother, Tass, has been left with lingering questions about the circumstances surrounding her death and the adequacy of the police investigation.
