Before dropping the charges, prosecutors indicated they were consulting with Serdar Caliskan's relatives in Turkey.

Caliskan was originally set to stand trial in the Victorian Supreme Court in March 2025, but the case was discontinued.

Ilknur Caliskan, 47, has had murder charges against her dropped following expert evaluations that suggested she may have acted involuntarily due to a sleep disorder.

The announcement of the discontinuation of charges was made during a brief court hearing on February 4, 2025, which Caliskan did not attend.

The decision to drop the murder charge followed a sleep study that raised questions about Caliskan's state of consciousness during the incident.

Caliskan claimed she was asleep during the incident, which occurred on September 30, 2023, while she and her husband, Serdar Caliskan, were camping near Colbinane.

Caliskan was released on bail in mid-2024 to undergo testing at a sleep facility in Sydney, as her defense team sought to explore parasomnia as a potential defense.

Parasomnia is a sleep disorder characterized by abnormal behaviors during sleep, which may explain Caliskan's actions during the incident.

Experts from both the defense and prosecution agreed that Caliskan could have been experiencing a sleep disorder at the time of the stabbing.

Serdar, aged 50, died at the scene despite paramedics' attempts to save him after being stabbed by Ilknur.

The prosecution initially charged Caliskan with murder after the stabbing incident during the camping trip.

A defense sleep expert testified that Caliskan was not acting consciously during the stabbing, while a prosecution expert could not rule out the possibility of a sleep disorder.
