Daniela D'Addario pleaded with ex-boyfriend to stop stalking her days before her murder.

By Tom Lowrey

A Canberra woman whose body was found in the back of a car abandoned by her ex-boyfriend on the NSW South Coast pleaded with him to stop stalking her in the days before she was murdered.

New details have emerged of the ordeal Daniela D’Addario, 35, was put through in the weeks before she was strangled by ex-boyfriend Josaia Vosikata, 29, in April 2015.

Vosikata pleaded guilty to her murder earlier this year, and appeared in the ACT Supreme Court on Friday for a brief hearing over disputed facts.

According to court documents, Vosikata became obsessed with Ms D’Addario after she ended their three-month relationship in early 2015.

He regularly sat outside her apartment in Bruce, sent her dozens of text messages and emails and formed a belief she may be pregnant with his child.

Nine days before her murder, Vosikata broke into Ms D’Addario’s apartment with a spare key in the early hours of the morning and attempted to sexually assault her, fleeing only when she called police.

Days later she emailed him, pleading with him to stop harassing her.

“Please listen to me … I do not ever want to see you again,” Ms D’Addario’s email read.

“Do not send me emails or texts or try to call me … Do not come to my house … Leave me alone!”

In the morning of April 19 Vosikata gained entry to Ms D’Addario’s apartment, straddling her on her bed and strangling her to death.

Shortly afterwards he filmed himself having sex with her body.

At around lunchtime he returned to the apartment he shared with his mother, where he had lunch with her and watched television.

Murderer botched attempt to dump car and body in ocean.

The next day, Vosikata placed Ms D’Addario’s body in the back of her car, and drove to Bermagui on the NSW South Coast.

After sleeping overnight at Cutagee Beach, he later attempted to drive the car, with the body inside, into the ocean, but it became stuck in the sand.

He spent another night at the beach with the car bogged before flagging down council workers the next morning to help him free the vehicle.

They noticed the car was full of clothes and rubbish, but after helping free it, shook Vosikata’s hand and left.

Two days later police spotted the car, but Vosikata escaped into bushland as officers approached the car.

He was apprehended a short distance away less than a day later.

Defence lawyers dispute details ahead of sentencing.

Vosikata returned to the ACT Supreme Court on Friday for a disputed facts hearing.

Prosecutor Jon White and defence barrister Paul Edmonds argued two points of contention. The first regarded whether Vosikata trespassed into Ms D’Addario’s apartment on the day of her murder, while the second was whether he took “rapid fixer” photographic fluid to her apartment for the purpose of incapacitating her.

Justice John Burns reserved judgement, but indicated he will make a ruling before Vosikata’s sentencing in August.
