Many of those gathering at Lake Harriet Park in southwest Minneapolis for the sunset memorial wore blue, Ruszczyk's favorite color.
The sound of two didgeridoos being played next to the Australian flag highlighted Ruszczyk's heritage. Plans called for luminarias and a silent walk around the lake at the end of the memorial.
Ruszczyk's fiance, Don Damond, said the two were planning to marry next week.
"Some would call it a cruel irony, but it's just an irony that we would have been on the airplane now, heading for a Hawaiian destination," he said. "It's rather surreal, but the irony isn't lost on any of us."
Ruszczyk, 40, called 911 late July 15 to report a possible sexual assault in the alley near her home. Less than 30 minutes later, she was dead from a gunshot wound
to the abdomen, having been shot by one of the two police officers who responded to the call.
Officer Matthew Harrity told investigators that he drove to the scene and was startled by a "loud sound" near the squad car, according to Minnesota's Bureau of Criminal Apprehension. Immediately afterward, Ruszczyk approached the driver's side window, and Harrity's partner, Mohamed Noor, shot Ruszczyk through the window, Harrity said.
A search warrant from Hennepin County District Court obtained by Minneapolis Public Radio suggests that startling sound may have been Ruszczyk slapping the patrol car
Noor declined to be interviewed by investigators
, and his attorney did not clarify when if ever he would give an interview. Investigators cannot compel him to give an interview.
Both Harrity and Noor are on administrative leave amid the investigation into the shooting.
"Justine, my daughter, was killed by a bullet fired by an agent of the state," John Ruszczyk said at the memorial. "I don't understand. I should have been on a plane to her wedding (rather than) flying to her funeral.
"This is our first visit to Minneapolis," he said. "We should be walking arm in arm down the street."
Beloved spiritual healer
Though she was a veterinary surgeon in her native country, Ruszczyk worked as a spiritual healer, yoga and meditation instructor and life coach in Minnesota. Friday's memorial was hosted by the Lake Harriet Spiritual Community, the organization where she worked.
Her friends have said the concern Ruszczyk showed that night for a possible assault victim was characteristic of her caring nature.
Video of Ruszczyk
rescuing a group of ducklings from a storm drain, carrying them out in her skirt and reuniting them with their mother nearby, was another example, friends and family have said. T
hey showed the video at the memorial.
Damon said Ruszczyk, despite being very dirty from the sewer, was overcome with happiness after helping the ducks.
"She came home that night and said, 'I just reached utopia.' She leaned against the wall and looked up. I thought it might be (that) somebody had a breakthrough or something really big. (But she said) 'I rescued eight ducklings.'"
