The Southport Magistrate’s Court heard accused murderer Kaihana Tahsseen Hussain told police her father had once threatened to kill her if she abandoned the Muslim faith.
Hussain has been charged with murdering her mother, Shaheda.
A forensic officer told Hussain’s committal hearing yesterday that police also told her the defendant had alleged that her mother had tried to strangle her during an argument three months before the October 2006 tragedy.
Anne-Louise Swain said the teenager’s injuries were consistent with her claims that her father Muhammad killed his wife and tried to kill her before turning the knife on himself.
However, Dr Swain could not say categorically whether the teenager’s injuries were sustained fending off an attack or from performing the attack.
Hussain is accused of her mother’s murder and the attempted murder of her father, allegedly over their opposition to her desire to change religions, just days after the family had moved to the Gold Coast.
Dr Swain said she examined Hussain on the night of October 9, observing injuries including scratches, bruises and bite marks on the then 17-year-old.
The girl, who was at that stage not being treated as a suspect in the killing, said her father had killed her mother, tried to strangle her and then slammed her fingers in a door as she tried to escape the murder scene.
She also had dried blood on her hands, but when Dr Swain removed it there were no injuries underneath.
Rodney Benson, a paramedic who treated Muhammad Hussain at the Smith St unit complex, said the former Bangladesh and Adelaide doctor asked police to arrest his daughter because “she stabbed me and my wife”.
The hearing continues today.
