An Australian woman who was about to get married was fatally shot overnight Saturday by a Minneapolis police officer who did not have his body camera turned on, officials said.

The woman, Justine Damond, was shot as the officers were responding to her 911 call of an assault near her home in the Fulton neighborhood. Ms. Damond, 40, who is from Sydney and who also went by the name Justine Ruszczyk, was engaged to be married next month to an American man, according to Australian news reports.

Police officials said they were looking into the circumstances of the shooting and why the officers were not using their body cameras, as required in such encounters.

“Two Minneapolis police officers responded to a 911 call of a possible assault just north of the 5100 block of Washburn Avenue South just before 11:30 p.m. Saturday,” a statement by the State Bureau of Criminal Apprehension said. “At one point an officer fired their weapon, fatally striking a woman.”
