The girl was arrested Dec. 8.
Park Ridge PoliceCmdr. Lou Jogmen said Maine South’s school resource officer and deans were informed that the girl, a student, was allegedly attempting to sell marijuana-laced brownies to other students for $10 each.
The student was sent to the Dean’s Office, where five brownies were found inside her backpack, Jogmen said. According to the police report the student admitted the brownies contained marijuana, he said.
The brownies will require crime-lab testing to determine the amount of marijuana they contain, Jogmen said.
The teenager is awaiting a petition to Juvenile Court. She was released to a parent following her arrest.
