A Victorian mum who killed her partner with a pickaxe before dating his best friend was a victim of family violence, her barrister says.
Angela Williams hit Douglas Kally 16 times with the axe and buried his body in the yard of the Indented Head home they shared with their two children.
She then told people that her partner of 23 years had left her to move to his favourite NSW fishing spot, the Victorian Supreme Court heard on Wednesday.
Williams, 45, admits to killing Mr Kally but claims she lashed out to protect herself after years of abuse.
Her lawyer Leonard Hartnett told her murder trial that domestic violence would be a key issue in the case.
He said Mr Kally “terrorised the family and terrorised them for a number of years”.
Prosecutor Brendan Kissane said Williams started a relationship with Mr Kally’s best friend, David Granger, within two weeks of killing him in July 2008.
He said when friends asked about Mr Kally’s whereabouts, Williams staged a telephone call in front of them, claiming Mr Kally was on the other end of the line.
“At that stage he was well and truly in the backyard,” Mr Kissane told the jury.
Williams also gave a watch to their son, saying Mr Kally had posted it as a birthday present, Mr Kissane said.
Police did not find Mr Kally’s body until December 2012, when Williams admitted to killing him, the court heard.
She told police Mr Kally had been pushing and shouting at her in their bedroom as he accused her of infidelity with Mr Granger.
She said she grabbed a pickaxe from behind their bedroom door and Mr Kally taunted her by saying “do it you f***ing fat slut”.
Williams then attacked him, leaving him lying dead on the bed as she sought comfort at the home of Mr Granger.
She returned the next morning to drop her kids to school and bury Mr Kally, Mr Kissane said.
The trial continues.
