Ramirez Dewberry, 24, was charged Jan. 8 with first-degree criminal sexual conduct, among other charges.
Prosecutor Kym Worthy alleges Ramirez Dewberry grabbed the victim by her arm as she was walking to school the morning of December 10, 2014.
Authorities say a gun was pointed at the victim's head, and she was taken to a vacant home in the 80th block of Church Street where the alleged sexual assault took place. The victim ran home and Highland Park police were immediately contacted.
Dewberry also faces charges of second-degree criminal sexual conduct, felonious assault and felony firearm.
Dewberry is due in court on January 23 for his preliminary examination.
