Family and friends of slain Australian woman Justine Damond are remembering her life at a memorial service in the US city of Minneapolis.
Around 1000 people, many dressed in blue, have gathered for the memorial service in the Minnesota city to celebrate the Australian spiritual teacher's life following her untimely death last month.
Grieving friends, family members, supporters and the local Minneapolis community have gathered for the memorial, which has included prayer, song, a Native American sage burning ceremony and a walk around picturesque Lake Harriet.
Damond's father John Ruszczyk and other Australian family members have flown to Minneapolis to attend the event at the Lake Harriet Bandshell.
The service commenced at 9am Saturday AEST with many mourners wearing blue -- Damond's favourite colour.
The slain Australian's fiance, Don Damond, said it felt surreal to be speaking at her memorial.
He said if Justine was still alive the pair, who were due to be married, would have been on their way to Hawaii together.
"One of the things I can do is express my vows of love to Justine," he told the service. "It felt like a privilege to love Justine."
The commemorative service comes after 40-year-old Damond was fatally shot in July by Minneapolis police officer Mohamed Noor outside her home after reporting a possible sexual assault in an alley.
Tears will flow at the service as questions remain about the circumstances of Damond's death.
Officer Noor has refused to speak publicly or open up to investigators probing why he lethally shot Damond in the abdomen when she approached his patrol car in her pyjamas.

The Australian Government has previously demanded answers over the killing, which Prime Minister Malcolm Turnbull has labelled "inexplicable".
"I mean, how can a woman out in the street in her pyjamas, seeking assistance from the police, be shot like that?" Turnbull said recently.
"We are providing all the support we can. It seems inexplicable, but there will be some answers given in due course. At this point, it is a tragic loss.
"Our hearts go out to her family with sorrow and condolence and love."
