The officer's body camera was not turned on at the time and this has raised questions. The woman's family and Minneapolis' Mayor are demanding answers.
Justine Damond used her fiance's surname despite not yet being married. They were to have their wedding in August. He was away on a business trip when she was killed. She wrote in her online profile that she was working as a spiritual healer and meditation coach. She had studied and practised yoga and meditation for more than 17 years and was also a trained veterinarian.
The Minnesota Bureau of Criminal Apprehension (BCA), which is investigating the incident, said two officers responded to “a call of possible assault" when “at one point an officer fired their weapon, fatally striking a woman". The BCA added that the officers’ body cameras were not turned on at the time of the incident and that they are investigating.
Following the shooting, her 22-year-old stepson Zach, whose dad Don, 50, was due to marry Justine in August, released a video saying he wanted answers.
Zach said: "Basically, my mom's dead because a police officer shot her for reasons I don't know. I demand answers. If anybody can help, just call police and demand answers. I'm so done with all this violence."
Hundreds of people gathered outside Justine's home on Sunday to mourn her. Neighbours described her as a kind and generous woman who helped people out when they were in need. They also said she and her fiance were so in love.
