    Sec. 5-4.5-105. SENTENCING OF INDIVIDUALS UNDER THE AGE OF 18 AT THE TIME OF THE COMMISSION OF AN OFFENSE.
    (a) On or after the effective date of this amendatory Act of the 99th General Assembly, when a person commits an offense and the person is under 18 years of age at the time of the commission of the offense, the court, at the sentencing hearing conducted under Section 5-4-1, shall consider the following additional factors in mitigation in determining the appropriate sentence:
        (1) the person's age, impetuosity, and level of
    
maturity at the time of the offense, including the ability to consider risks and consequences of behavior, and the presence of cognitive or developmental disability, or both, if any;
        (2) whether the person was subjected to outside
    
pressure, including peer pressure, familial pressure, or negative influences;
        (3) the person's family, home environment,
    
educational and social background, including any history of parental neglect, domestic or sexual violence, sexual exploitation, physical abuse, or other childhood trauma including adverse childhood experiences (or ACEs);
        (4) the person's potential for rehabilitation or
    
evidence of rehabilitation, or both;
        (5) the circumstances of the offense;
        (6) the person's degree of participation and specific
    
role in the offense, including the level of planning by the defendant before the offense;
        (7) whether the person was able to meaningfully
    
participate in his or her defense;
        (8) the person's prior juvenile or criminal history;
        (9) the person's involvement in the child welfare
    
system;
        (10) involvement of the person in the community;
        (11) if a comprehensive mental health evaluation
    
of the person was conducted by a qualified mental health professional, the outcome of the evaluation; and
        12 any other information the court finds relevant and
    
reliable, including an expression of remorse, if appropriate. However, if the person, on advice of counsel chooses not to make a statement, the court shall not consider a lack of an expression of remorse as an aggravating factor.
    (b) The trial judge shall specify on the record its consideration of the factors under subsection (a) of this Section.
    (c) Notwithstanding any other provision of law, if the court determines by clear and convincing evidence that the individual against whom the person is convicted of committing the offense previously committed a crime under Section 10-9, Section 11-1.20, Section 11-1.30, Section 11-1.40, Section 11-1.50, Section 11-1.60, Section 11-6, Section 11-6.5, Section 11-6.6, Section 11-9.1, Section 11-14.3, Section 11-14.4 or Section 11-18.1 under Criminal Code of 2012 against the person within 3 years before the offense in which the person was convicted, the court may, in its discretion:
        (1) transfer the person to juvenile court for
    
sentencing under Section 5-710 of the Juvenile Court Act of 1987;
        (2) depart from any mandatory minimum sentence,
    
maximum sentence, or sentencing enhancement; or
        (3) suspend any portion of an otherwise applicable
    
sentence.
    (d) Subsection (c) shall be construed as prioritizing the successful treatment and rehabilitation of persons under 18 years of age who are sex crime victims who commit acts of violence against their abusers. It is the General Assembly's intent that these persons be viewed as victims and provided treatment and services in the community, juvenile or family court system.
    (e) Except as provided in subsection (f), the court may sentence the defendant to any disposition authorized for the class of the offense of which he or she was found guilty as described in Article 4.5 of this Code, and may, in its discretion, decline to impose any otherwise applicable sentencing enhancement based upon firearm possession, possession with personal discharge, or possession with personal discharge that proximately causes great bodily harm, permanent disability, permanent disfigurement, or death to another person.
    (f) Notwithstanding any other provision of law, if the defendant is convicted of first degree murder and would otherwise be subject to sentencing under clause (iii), (iv), (v), or (vii) of subparagraph (c) of paragraph (1) of subsection (a) of Section 5-8-1 of this Code based on the category of persons identified therein, the court shall impose a sentence of not less than 40 years of imprisonment, except for persons convicted of first degree murder where subsection (c) applies. In addition, the court may, in its discretion, decline to impose the sentencing enhancements based upon the possession or use of a firearm during the commission of the offense included in subsection (d) of Section 5-8-1.
