(CNN) Former Minneapolis police officer Mohamed Noor was sentenced Friday by a Minnesota judge to 12½ years in prison for the fatal shooting of a woman while responding to her 911 call.

Noor, a 33-year-old Somali-American, was convicted April 20 on charges of third-degree murder and manslaughter in the death of Justine Ruszczyk, who had relocated from her native Australia to Minneapolis to live with her fiancé.

During the sentencing hearing, Ruszczyk's fiancé, Don Damond, read a letter in which he described weeping in a dress shop when he saw her wedding dress a week after her death.

"I had an experience of what that magical wedding night in Hawaii would have been like," he said. "I fantasized about seeing you walk on the beach in that dress toward me to exchange our vows. I fantasized kissing you as they designated us man and wife.

"But these are not memories but sad wishes of what will never be."
