Story highlights Australian PM says his government wants answers into 'shocking' event

Mourners in her hometown pay tribute to much-loved woman in beach-side dawn ceremony

(CNN) Australia's prime minister has demanded answers to the "inexplicable" killing of an Australian-American woman shot by police in Minneapolis.

"This is a shocking killing. It is inexplicable," Prime Minister Malcolm Turnbull told Australian Channel 9's "Today" program Wednesday, in his first public comments since Justine Ruszczyk's death on Saturday.

"I mean, how can a woman out in the street in her pyjamas seeking assistance from the police be shot like that?" he said. "We are demanding answers, something clearly went tragically wrong."

Ruszczyk had called 911 to report a possible sexual assault near her home, her fiancé, Don Damond, said Monday.

Two police officers responded, and one of them, Mohamed Noor, shot her in the abdomen, killing her, according to police and an autopsy report.
