Section 2. A person may file a motion for forensic or scientific analysis under this chapter if that person: (1) has been convicted of a criminal offense in a court of the commonwealth; (2) is incarcerated in a state prison, house of correction, is on parole or probation or whose liberty has been otherwise restrained as the result of a conviction; and (3) asserts factual innocence of the crime for which the person has been convicted.
