Rachael Williams was hoping to leave her drug problem behind when she moved from Melbourne to the Illawarra in early-2009. But in her new home, her habit grew worse than ever. Benzos and heroin. Soon she'd do anything for them.
She says she was "desperate for drugs" by October 2010, when she received a late-night message from David Bagster, boyfriend of her friend, Valmai "Jane" Birch.
Bagster was proposing sex and "his version of bondage", with he and Ms Birch, in exchange for drugs. Ms Williams took two Xanax tablets to "give me the courage" before arriving at Ms Birch's Woonona home by taxi about 2am, she would later tell a Wollongong District Court jury.
She described stepping inside the house to find Ms Birch crouched in a corner, with her bloodied hair covering her face and her wrists and ankles bound so tightly her extremities were blue.
"I saw her crumpled ... She had her head down. She had very long hair and part of it was dark - it looked like blood - and her feet and hands were a blue/red colour - like there was no circulation," Ms Williams said in evidence, on Monday.
"There was some sort of string or rope holding [her] wrists to feet.
"She wouldn't look at me."
Bagster is on trial for manslaughter, accused of unlawfully killing Ms Birch several months after the encounter Ms Williams describes. The 34-year-old's decomposing, hogtied body was found face-down inside a wheelie bin at her Woods Avenue unit on March 22, 2011.
Ms Williams choked back tears on Monday, conceding she never sought help for her friend the night she found her injured. She said she found Bagster elsewhere in the house and left soon afterwards, walking all the way home to Fairy Meadow.
"I said something about drugs - 'you haven't got drugs'. ... I used it as an excuse to get out of there," she said, later adding she was "terrified" of Bagster.
"You didn't try and help Jane?" defence barrister Scott Fraser asked.
"No. I abandoned her, and I regret it."
Ms Williams said Ms Birch showed her marks and bruises on her body when she saw her several days later, but that she "seemed happy". That was the last time she saw her alive. Ms Williams described Ms Birch as "a very kind and very gentle woman", who could be both strong and vulnerable. The court heard Ms Birch's mother had died when she was young and her father wasn't in her life, and she received a trust fund.
"She was very easily taken advantage of because of her extra trust fund money," Ms Williams said in evidence.
She told the court Ms Birch had stopped working as a sex worker, secured housing in Woonona and was on the methadone program in the lead-up to her death.
In later evidence Monday an acquaintance of Ms Birch's, Teena Costa, said Bagster was slurring his words when he visited her sister Leonie's house around late-March 2011. Ms Costa told police Bagster laughed and replied, "haven't you heard?" when he was asked where his girlfriend was.
"He said, 'we got on the pills last night and I bashed her in the bath tub. I couldn't get her out so I put her in the wheelie bin'," Ms Costa later told police, in a statement.
Under cross-examination Ms Costa was challenged on her timeline of events and other details, asked how Bagster could have been refering to the events of "last night" if Ms Birch's body had already been found by then.
"Were you aware that Jane's unit didn't have a bath tub?" Mr Fraser asked.
"No," she replied.
The trial continues.
