(a) If the State's Attorney files a petition, at any time prior to commencement of the minor's trial, to designate the proceeding as an extended jurisdiction juvenile prosecution and the petition alleges the commission by a minor 13 years of age or older of any offense which would be a felony if committed by an adult, and, if the juvenile judge assigned to hear and determine petitions to designate the proceeding as an extended jurisdiction juvenile prosecution determines that there is probable cause to believe that the allegations in the petition and motion are true, there is a rebuttable presumption that the proceeding shall be designated as an extended jurisdiction juvenile proceeding.
(b) The judge shall enter an order designating the proceeding as an extended jurisdiction juvenile proceeding unless the judge makes a finding based on clear and convincing evidence that sentencing under the Chapter V of the Unified Code of Corrections would not be appropriate for the minor based on an evaluation of the following factors:
(i) the age of the minor;
(ii) the history of the minor, including:
(A) any previous delinquent or criminal history of the minor,
(B) any previous abuse or neglect history of the minor, and
(C) any mental health, physical and/or educational history of the minor;
(iii) the circumstances of the offense, including:
(A) the seriousness of the offense,
(B) whether the minor is charged through accountability,
(C) whether there is evidence the offense was committed in an aggressive and premeditated manner,
(D) whether there is evidence the offense caused serious bodily harm,
(E) whether there is evidence the minor possessed a deadly weapon;
(iv) the advantages of treatment within the juvenile justice system including whether there are facilities or programs, or both, particularly available in the juvenile system;
(v) whether the security of the public requires sentencing under Chapter V of the Unified Code of Corrections:
(A) the minor's history of services, including the minor's willingness to participate meaningfully in available services;
(B) whether there is a reasonable likelihood that the minor can be rehabilitated before the expiration of the juvenile court's jurisdiction;
(C) the adequacy of the punishment or services.
In considering these factors, the court shall give greater weight to the seriousness of the alleged offense, and the minor's prior record of delinquency than to other factors listed in this subsection.
