Australian woman Justine Damond was wearing her pyjamas when shot dead on Saturday night by Minneapolis Police, it has now been revealed.
According to The Star Tribune, the "officer-involved shooting" occurred when the 40-year-old went to the driver's side door of the police car responding to her 911 emergency call for help.
It comes as the Minnesota Public Safety Department confirmed Ms Damond was shot on Saturday night local time.
Originally from Sydney, Ms Damond was engaged to an American man, and had reportedly called police after hearing a noise near her house.
The woman's stepson Zach Damond has taken to Facebook Live, seeking answers and condemning gun violence in the United States.
"My mum is dead because the police officer shot her for reasons I don't know and I demand answers," he said.
Zach says his mother was "passionate", and his best friend.
"I just know she heard a sound in the alley so then she called the police and the cops showed up and she was a very passionate woman, she probably thought something bad was happening and then next thing I know they take my best friend's life."
It's now been revealed the responding police officers' body cameras were not recording at the time.
"The officers' body cameras were not turned on at the time and the squad camera did not capture the incident," the Bureau of Criminal Apprehension said in a statement.
"Investigators are attempting to determine whether any video of the incident exists."
A Department of Foreign Affairs and Trade spokesperson says consular assistance is being offered to the family involved.
