A martial arts expert accused of murdering his girlfriend of eight weeks contacted another woman early the next morning asking if she wanted sex, a NSW court has heard.
In his opening address to a Supreme Court jury in Newcastle on Monday, crown prosecutor Lee Carr SC said Sayle Kenneth Newson sent a Facebook message to the woman at 5.30am asking "Do you want to f***?" the day after he allegedly killed mother-of-two Carly McBride. The pair met up the following day and had sex.
Mr Carr said evidence during the trial would show Newson became aggressive and violent when drug affected and that he had been taking ice for a couple of days before he killed Ms McBride.
The prosecutor said Newson and a friend, James Anthony Cunneen, later dumped the body in bushland.
Mr Carr said the case against the two men was circumstantial and there was no "smoking gun" but all the facts would build a picture proving their guilt.
He said there would be evidence detailing Newson's jealousy and possessiveness when he was in a relationship and how he had a "controlling attitude".
Newson, 41, from Buff Point on the Central Coast, has pleaded not guilty to murdering Ms McBride, 31, on September 30, 2014.
Cunneen, 27, of Muswellbrook, has pleaded not guilty to being an accessory after the fact to murder.
Ms McBride's remains were found in bushland at Owens Gap, about 17 kilometres northwest of Scone, on August 7, 2016. Her hands were missing and there had been no attempt to bury or conceal the body.
A post-mortem revealed she had suffered blunt force trauma to her face and back of her head, indicating she had suffered at least two blows to the skull and one to her back.
Ms McBride had met Newson and Cunneen at a drug and rehabilitation centre west of Wyong in late 2013 before she began a relationship with Newson in early August 2014.
Mr Carr said Newson had dropped off Ms McBride to visit her daughter at her ex-partner's home at 12.30pm on the day she disappeared and later intercepted her as she was walking to meet him at the local McDonald's.
Newson allegedly murdered Ms McBride some time after 2pm before dumping her body.
The prosecutor said the couple had argued two days earlier about Ms McBride communicating with other men on Facebook.
Mr Carr said Newson later searched the internet on how to delete a Facebook account before Ms McBride's Facebook account was deactivated on September 29.
The trial, before Justice Mark Ierace, continues.
