Armstrong pleaded not guilty to the charge and had allegedly tried to escape custody while being escorted to a doctor's appointment. The sentencing phase of the trial is expected to begin on Monday, and Armstrong could face up to 99 years in prison for the murder conviction and up to 20 years in prison for the second charge.
