A judge entered a not guilty plea on behalf of Nikolas Cruz.
The 19-year-old has been charged with 17 counts of premeditated first-degree murder and 17 counts of attempted first-degree murder for a deadly shooting last month in Parkland, Florida.
Cruz allegedly confessed to authorities after the shooting at Marjory Stoneman Douglas High School.
Though he initially entered a not guilty plea, Cruz chose to change his plea and stay mute to his charges, after a grand jury formally indicted him.
