A Melbourne man, who drowned his ex-lover in her bathtub in what he long claimed was a death pact, has pleaded guilty to her murder.
Murat Davsanoglu was on trial for murder, but the Supreme Court jury was discharged on Friday morning, a day after the 43-year-old confessed in the witness box he had "snapped" and murdered Ozlem "Ozzie" Karakoc, 34.
The confession came two weeks into the trial and after 18 months of him claiming her death in Dandenong last July was the result of a suicide pact they were discussing for months previously.
Prosecutor Diana Piekusis SC had been questioning Davsanoglu about whether he had considered his actions would leave Ms Karakoc's daughter without a mother.
"You weren't thinking of (the girl) at all, were you?" she asked.
"No. Miss, you don't need to go any further. I just snapped that night, okay, that's it."
He maintained there was a suicide pact, but not on the night he drowned her.
Davsanoglu and Ms Karakoc had been in an open relationship over an 18-year period before her death.
He admitted he was angry she had started a new relationship and at the thought of losing her.
"That's the reason you killed her," Ms Piekusis said.
"That is correct, miss, yes," Davsanoglu said.
Justice Lex Lasry sought clarification.
"So there was no suicide pact on that night?" he asked.
"Not on that night, no," Davsanoglu replied.
Only an hour before confessing, he claimed the suicide pact was developed over the five months before the July 14 murder.
He said they discussed plans face to face for several months, as well as over WhatsApp messages that he later deleted and could not be retrieved by police.
The trial previously heard Ms Karakoc had a major depressive disorder with psychotic episodes, but her psychologist Semra Durmaz said she never expressed suicidal thoughts to her.
She spoke to Ms Karakoc on the phone days before her death.
"It was the first time I heard her sound so happy," she told the jury last week.
Witness box confessions are highly unusual and after the admission, Davsanoglu's lawyer John Desmond revealed after the jury was sent home that "family members were very concerned he is just now going to say anything because he is worn down".
Ms Karakoc's family, in court for the guilty plea, hugged prosecutors after the hearing, relieved at getting justice for the young mum.
Members of Davsanoglu's family were also present. He gave them a grimacing smile as he was taken from court.
He'll return for a plea hearing and sentence next year.
