Twenty-four-year-old Mahtab Shirani allegedly sent e-mails to administrators on Friday, threatening a mass shooting. One stated, "After NIU, it's UIC'sturn to face disaster."
Campus police traced the e-mail and identified Shirani's user ID. Video surveillance also showed her leaving the computer lab where the messages were sent.
Shirani is charged with felony disorderly conduct. She faces one to three years in prison if convicted.
