The woman died following an officer-involved shooting, according to Minneapolis police.
The shooting occurred on the 5100 block of Washburn Avenue South in the city's Fulton neighbourhood.
Two officers responded to a 911 call about a possible assault in the alley off of West 51st Street between Washburn and Xerxes avenues around 11.30pm, according to a statement released Sunday by the Minnesota Bureau of Criminal Apprehension.
"At one point one officer fired their weapon, fatally striking a woman," the BCA said.
The dead woman, who has not yet been identified pending notification of relatives overseas.
His son Zach Damond took to Facebook saying he "heard noise in the alley and called the police".
"Investigators are attempting to determine whether any video of the incident exists."
Mr Damond said the woman, reportedly an Australian in her 40s, was "passionate" and his "best friend".
"Basically my mum was shot for reasons I don't know," Mr Damond said in a video posted on Facebook on Monday morning (AEST).
"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."
Minneapolis mayor Betsy Hodges said she intended to find out why the officers' body cameras were not turned on.
"As mayor of our city, a wife, and a grandmother, I am heartsick and deeply disturbed by what occurred last night," she posted on Facebook.
The woman was to be married to Mr Damond, 50, in August, according to Hannah, a close family friend, the Star Tribune reports.
Mr Damond was on a business trip and returned home Sunday afternoon after the tragedy occurred.
Activist Mel Reeves, who was at the scene told his Facebook followers that a vigil to support the family would be held at 6pm Sunday on 51st Street near where the shoting occurred.
Hannah said the woman worked as "a spiritual healer" and that "she was the most loving woman" who "kind of flowed through the house so lightly."
The Hennepin County Medical Examiner will conduct an autopsy and release details, including the victim's name and the cause and manner of her death.
Investigators are also trying to determine whether video of the incident exists, as officers' body cameras were turned off at the time and cameras in the police car did not capture the incident, according to a statement from the Department of Public Safety.
