Serdar Caliskan and wife Ilknur
The family of a man killed by his wife while she was sleepwalking has blasted Victoria’s Office of Public Prosecutions (OPP) after she walked free because a murder charge could not be proven.

In 2023, Serdar Caliskan, aged 50, was fatally stabbed by his wife Ilknur, aged 47, during a camping trip. Surprisingly, the murder charge against Ms. Caliskan was dismissed because of her documented sleep disorder.

Mr Caliskan’s family told 9News they have been in “hell” since his death and believe the justice system has let them down.

Mr Caliskan’s family claim in the 26 years the pair were married, his wife’s sleep disorder was never mentioned.

“His parents had never heard of this,” Gover said.

“They lived in a house together for over a month. No mention of this.”

Mr Caliskan’s family are calling for restrictions to be put on people like Ms Caliskan who are freed.

“Our concern is the community and her kids who live in the same house as her,” Gover said.

The OPP told 9News the decision to drop a murder charge was not done lightly.

The OPP stated, “Following a thorough evaluation of input from various specialists, it was concluded that the criteria for murder could not be sufficiently established to a level of certainty required by law.”
