A Geraldton doctor decided to kill her husband because she was concerned about the sexual relationship they had both formed with a teenager, a court has been told.
Chamari Rasika Denuwanthe Gunathilaka Liyanage is on trial in the Supreme Court accused of murdering her doctor husband, Dinendra Athukorala, at their Shenton Street home in June 2014.
It is alleged Dr Liyanage fatally injured Dr Athukorala when she repeatedly hit him with a 1.79kg hammer as he lay on their bed.
In his opening address, prosecutor Nick Cogin said Dr Athukorala engaged in unusual sexual practices, wanted to have sex with other women and wanted to involve his wife in these activities.
He said the Sri Lankan couple developed a sexual relationship with a 17-year-old girl and this left Dr Liyanage worried about her career.
Mr Cogin claims Dr Liyanage became fed up with her circumstances and thought the only way of resolving things was by killing her husband.
“It got to a stage that she was no longer prepared to put up with his behaviour,” he said.
Mr Cogin said Dr Liyanage was huddled in the lounge room in the foetal position when police arrived at the home.
It is alleged blood had splattered on her clothes and the wall of the bedroom.
During a police interview, Dr Liyanage said her husband was physically violent, forced her to engage in sexual acts and controlled her movements and finances.
Defence lawyer George Giudice described his client as a “sleep deprived, anxious, trapped and battered woman”.
He said Dr Liyanage was made to model for her husband in front of a camera, sometimes for hours on end.
Mr Giudice said Dr Liyanage could not remember if she was the one who did the act that killed Dr Athukorala.
The triple-0 call Dr Liyanage made at 6.11am was played to the jury earlier today.
She could be heard sobbing and crying uncontrollably throughout the call while the operator asked her questions.
“Oh my god, I don’t know what’s happened to my husband,” Dr Liyanage said.
One of the police officers who was first on the scene, Snr Const Brian Bird, told the court Dr Athukorala’s lifeless body was on the bed and a pillow was over his head when he arrived.
“I observed a wooden handle mallet lying to the deceased’s left hand side,” he said.
Snr Const Bird said Dr Liyanage was upset, crying and distressed when she opened the door.
The trial continues.
