THE investigation into Justine Damond's killing by Minneapolis cop Mohamed Noor has cleared its first stage.
Minnesota's Bureau of Criminal Apprehension has handed over its preliminary investigation to the Hennepin county lawyer, who will now decide next steps.
County lawyer Mike Freeman has said he is considering a murder charge against Noor.
Justine Damond, 40, was shot and killed by Officer Mohamed Noor on July 15 after she called 911 to report a possible sexual assault happening outside her home.
His partner, Officer Matthew Harrity, has told investigators that he heard a loud bang before Noor fired across him and hit Damond in the abdomen as she approached their police car. She died 20 minutes later despite CPR efforts.
Noor has refused to give a statement to police.
In a statement, Mr Freeman thanked the BCA for the "hard work" it had put into the investigation.
"Several senior prosecutors will now carefully review the case file to determine what, if any, charges might be brought," he said. "As is often the case in these types of investigations, the county attorney's office will remain in contact with the
BCA and may ask for additional investigation during this review."
The Star Tribune says Mr Freeman will make his decision by the end of the year.
Mr Freeman had previously told News Corp Australia that Noor could face a murder charge.
However, a charge of second-degree manslaughter is more likely, he said.
"In Minnesota normally it's a charge of second degree manslaughter,' Mr Freeman said. "[But] it's way too premature for us to make that call yet."
Damond was a month away from marrying her fiance, Don Damond, when she was shot in a killing that has stunned the local Minneapolis community and her loved ones back in Australia.
Mr Damond released a statement, urging Mr Freeman to make a quick decision.
"The BCA has concluded its investigation, but the wait continues for Justine's family and me. We want to see justice for Justine, and hope that the Hennepin County Attorney will act swiftly to review the findings and determine charges," he said.
