A woman now accused of murdering her mother two decades ago sobbed in her triple-zero call saying she had been choked by an intruder and "can't find my mum".
But prosecutor David Scully alleged that Isabela Carolina Camelo-Gomez had invented the story about an intruder after she strangled and stabbed her mother in her Sydney kitchen.
The then-27-year-old had been obsessed with a man her mother hated and her daughter believed she was an obstacle to their relationship, he told a jury during the crown opening address.
Camelo-Gomez, 47, has pleaded not guilty in the NSW Supreme Court to murdering Irene Jones on November 2, 2001 at her Lansvale home.
The 56-year-old was strangled with a ligature and stabbed in the neck.
The jury was played two triple-zero calls made from the home of Camelo-Gomez's neighbours, after she told them she had got out of the shower to be attacked by a man wearing a stocking over his face.
Mr Scully alleged that the woman previously known as Megan Jones killed her mother because of her infatuation and obsession with Carlos Camelo-Gomez and her belief her mother was an obstacle to the relationship.
She also allegedly wanted to please him by continuing to financially support him after she inherited her mother's house.
She allegedly had "a sham marriage" with his brother in Colombia to secure his residency in Australia in an attempt to please Carlos Camelo-Gomez, Mr Scully said.
"The deceased only found out about the marriage afterwards and she told her friend she was very upset," he said.
On the night she died, Ms Jones celebrated her birthday belatedly by going out to dinner with her daughter.
On their return, Camelo-Gomez allegedly killed her mother and scattered various items around the house to make it look like the work of a random intruder.
She was allegedly heard saying "sorry mum, I didn't mean for it to go this far" while standing near the coffin at the funeral, Mr Scully said.
She was not charged until September 2019 after the case was re-investigated by the Unsolved Homicide Unit.
Camelo-Gomez would not be giving evidence as he suffered a serious brain injury after a 2013 car accident.
He has "severe retrograde amnesia" meaning he is unable to remember events prior to the accident.
Camelo-Gomez, who worked in the office of The Church of Jesus Christ of Latter-day Saints, had met him through his wife who was also a member of the church.
The Crown alleged that by mid-2000 she was in love with him, telling a friend "she wanted to marry him and had never met anyone like him".
She visited a bridal shop and paid a deposit and made payments on a wedding dress, he said.
"The crown case is that the strong feelings she had were not necessarily reciprocated."
Mr Scully said Carlos Camelo-Gomez was using her, and she had paid for things for him and given him cash.
"The deceased hated Carlos Camelo-Gomez and thought he was using her (daughter) for money," he said.
While the Crown's primary case was that the daughter was the killer, Mr Scully said the alternative case was that she was liable because Carlos Camelo-Gomez or another person committed the fatal acts while she was present.
But defence lawyer Belinda Rigg SC also pointed to the jury to possibility that Carlos Camelo-Gomez was responsible for the death, submitting "the accused was not acting with him".
Her client disputed claims she wasn't attacked by an assailant in the home before her mother was found dead.
She also disputed being obsessed and infatuated with Carlos Camelo-Gomez and said they first had sex in February 2002 - months after the death.
Carlos Camelo-Gomez had a key to the house and evidence suggested he was in the vicinity of the house on the night of the murder, Ms Rigg said.
The trial continues before Justice Helen Wilson.
