Police are investigating the missing time gap between a mysterious triple-zero phone call and the death of a woman who jumped from a seven-story balcony.
Emergency services were called to a block of units on River Road in Parramatta about 1.40am on Thursday.
Officers arrived at the scene and discovered the woman, believed to be 39 years old, in the street with serious injuries.
Moments earlier, horrified onlookers had seen her hanging from the balcony.
Despite efforts to resuscitate the woman, she was pronounced dead at the scene. She has not yet been formally identified.
A 40-year-old man was detained at the scene and questioned by police. He has since been released without charge while investigations continue.
On Thursday afternoon it emerged that a triple zero call had been made from the apartment at 11.45pm, almost two hours before the woman fell to her death.
Nothing was said during the call, but the operator could hear “raised voices” in the background.
Forensics are seen at the balcony crime scene in Parramatta, west of Sydney, where a woman is believed to have fallen to her death during the early hours of Thursday.
What appeared to be a bloodstain could be seen at the cordoned off crime scene.
Police eventually called the number again and spoke to the man at the property, who revealed his name and address.
Officers confirmed they would visit the property but did not arrive until the woman fell from the balcony.
“Part of the investigation will be a review of a triple zero call made to the police radio at around 11.45pm last night,” Detective Superintendent Barry Vincent said.
“There was no conversation during that call and, despite two further calls from Triple-Zero, no contact could be made with the caller.
‘Officers from Parramatta Police Area Command were able to contact that number at 11.47pm, after which they spoke to a man and he was able to provide an address and his name and where the call had originated from.
He added: “The police informed the man that they would be present at his apartment.
“Following that phone call, police responded to further calls for assistance and shortly before 1.40am, police received calls from a neighbor in the River Road unit block following reports of a woman hanging from a balcony.”
‘That call was received at 1:40 a.m. and at 1:41 a.m. our officers responded to the scene, after which they found a woman at the entrance to a block of the unit and immediately began CPR. Despite their best efforts, the woman died at the scene.
The woman died at the scene after police were called to the complex at 1.40am.
Detectives were seen arriving at the unit block on River Road Thursday morning.
Superintendent Vincent revealed there had been “previous interactions” with police and the couple in question and that the man had had an AVO taken against the woman.
He said police “receive calls similar to this quite frequently and it is our standard practice to attend and confirm that everything is OK.”
“After assisting other addresses in response to other work, they were en route to that address when that (second) call for assistance came.”
He added: “These are assessments that our officers do routinely, the decision making around that is obviously something we will be looking at.”
Sai Pamula, who lives in the building, said she heard a “loud squishing noise” and ran to the street where she saw two men and the woman.
“Her partner didn’t panic, he was calm and kept saying ‘she’s not breathing, she’s not breathing’,” he told Daily Mail Australia.
He asked the other man to call the police. They came and did CPR.
Pamula said she had been told the couple was allegedly arguing in the street earlier that night.
Police were seen stopping and questioning residents as they left the underground parking lot.
The apartment tower on River Road, Parramatta, is just meters from a light rail station.
A resident is seen looking out the window of his unit as police continue their investigations.
Residents woke up Thursday to find their apartment tower surrounded by police.
“People tried to intervene but he just wouldn’t listen to them,” he added.
Uniformed officers were also seen inspecting residents at the apartment tower.
A neighbor on the top floor said her son woke up to the couple’s “screams and screams.”
“They were cursing each other on and off throughout the night. “I heard the word ‘ungrateful’ at one point,” she told Daily Mail Australia.
It sounded like something had been thrown to the floor. And then I heard a big bang and saw all the sirens.
Another neighbor who lives six floors above the balcony said he heard a “heartbreaking” scream at 12:47 a.m.
“I was half asleep watching TV in our living room and heard a distinctive female scream. I called my partner, who was in the other room, to ask if it was her,” he said.
The man went to bed, but realized the seriousness of the situation the next morning, when the officers cordoned off the street.
“I think she (the victim) landed in the flower bed,” he said.
‘It’s so horrible. The innocence of the building has completely disappeared.
