The CMPD officer involved in a fatal crash last month has been charged with involuntary manslaughter. The Charlotte Mecklenburg Police Department says Officer Martray Proctor turned himself in to the Mecklenburg County Sheriff's office earlier Thursday. The district attorney has charged Proctor with involuntary manslaughter in the death of 20-year-old Shatona Evette Robinson. A CMPD investigation found Proctor was driving more than 90-miles per hour with his sirens off the night of March 29th when he struck the driver's side of another vehicle, killing Robinson and injuring three others. Proctor was responding to a routine traffic stop. CMPD is still investigation whether Proctor's emergency blue lights were on. Proctor had received three speeding tickets since 2003 and has been on administrative leave since the accident. Proctor's attorney, George Laughrun says his client plans to plead not guilty. If convicted, Proctor could face nearly five years in prison.
