The Minnesota Supreme Court on Wednesday reversed the third-degree murder conviction of a former Minneapolis police officer who fatally shot an Australian woman in 2017, saying the charge doesn’t fit the circumstances in the case.

Mohamed Noor was convicted of third-degree murder and second-degree manslaughter in the death of Justine Ruszczyk Damond, a dual U.S.-Australian citizen who called 911 to report a possible sexual assault behind her home. He was sentenced to 12 1/2 years on the murder count but was not sentenced for manslaughter.

The ruling means his murder conviction is overturned and the case will now go back to the district court, where he will be sentenced on the manslaughter count. He has already served more than 28 months of his murder sentence. If sentenced to the presumptive four years for manslaughter, he could be eligible for supervised release around the end of this year.

Caitlinrose Fisher, one of the attorneys who worked on Noor’s appeal, said she’s grateful that the Minnesota Supreme Court clarified what constitutes third-degree murder, and she hopes that will lead to greater equity and consistency in charging decisions.

“We’ve said from the beginning that this was a tragedy but it wasn’t a murder, and now the Supreme Court agrees and recognizes that,” she said.

Messages left Wednesday with the Hennepin County Attorney’s Office, which prosecuted the case, were not immediately returned.

The ruling could give former Minneapolis Officer Derek Chauvin grounds to contest his own third-degree murder conviction in George Floyd’s death in May 2020. But that wouldn’t have much impact on Chauvin since he was also convicted of the more serious count of second-degree murder and is serving 22 1/2 years. Experts say it’s unlikely Chauvin would be successful in appealing his second-degree murder conviction.

The ruling in Noor’s case was also closely watched for its possible impact on three other former Minneapolis officers awaiting trial in Floyd’s death. Prosecutors had wanted to add charges of aiding and abetting third-degree murder against them, but that’s unlikely to happen now. The trio are due to go on trial in March on charges of aiding and abetting both second-degree murder and manslaughter.
