Harrowing Triple Zero Call: A Minute Of Screaming Then 10 Thuds

"I'm going to go to jail for life over this woman."

One afternoon in February 2015, Brock Wall drove to Fabiana Palhares’ house, woke her from a nap and murdered her with a tomahawk.

A heavily shackled Wall was today handed two life sentences.

One for the murder of his former girlfriend, and one for killing their unborn baby. Fabiana was up to 11 weeks pregnant.

The court heard Wall bashed Fabiana and jumped on her stomach at her Varsity Lakes home.

In one desperate final attempt to save herself, Fabiana managed to call triple zero.

The operator could hear screaming for one minute and then the sound of 10 thuds, as Wall hit Fabiana in the face and head with a tomahawk.

"Your attack became a murderous rage, which was clearly full of hate and anger." Justice Ann Lyons said.

"The facts are chilling, horrific and the stuff of nightmares."

Covered in blood, Wall left Fabiana dying in her bedroom, he was intercepted by police just 400 metres down the road.

Fabiana had taken out two domestic violence orders out against him after ending their relationship two months earlier.

In the weeks leading up to her death, Wall stalked and harassed her.

Wall had told work mates "I'm going to f**king kill her. I might punch her in the guts first."

"I'm going to go to jail for life over this woman."

The 38 year-old occassionally sniffed and wiped his eyes during his sentencing. However it was no match for the raw emotion from police, members of the media and of course family and friends of Fabiana in the courtroom.

Her former housemate Bianca Gouveia stared down Wall, only occassionally leaning back in her seat to be comforted by friends and police.

"Life has changed, trust has changed and our hearts are still broke," Gouveia said outside the court.

"I still cannot believe that this has happened, you said you loved Fabiana but you didn't know her because if you knew her you would have never killed her."

Fabiana's brother Raphael and his wife travelled from Brazil to attend today's sentencing. He said the family is satisfied with two life sentences.

When asked if he had anything to say to Wall, Raphael said "I would just ask him why. There is no reason for you to do what you did."

Days before the trial was due to start, Wall pleaded guilty.

He has a non-parole period of 20 years.
