MINNEAPOLIS — Former Minneapolis police officer Mohamed Noor was convicted Tuesday on charges of third-degree murder and second-degree manslaughter in the killing of 911 caller Justine Ruszczyk. The jury acquitted him of second-degree intentional murder. Noor was led out of the courtroom in handcuffs following the verdict. Sentencing is scheduled for June 7. It's believed to be the first time a police officer in Minnesota has been convicted of murder for shooting someone while on duty. Nationwide, such convictions are extremely rare.
