CHICAGO -- A Cook County judge set bond at $75,000 Sunday for a female University of Illinois at Chicago student who allegedly sent e-mails threatening a mass shooting to three UIC administrators on Friday.

Mahtab Shirani, 24, was arrested Saturday morning and faces charges of felony disorderly conduct for the Friday's e-mails, sent one day after a Northern Illinois University shooting massacre that killed six people.

"This e-mail sent threats that a mass shooting was going to occur somewhere on campus during the spring semester of 2008," said Assistant State’s Attorney Melanie Fialkowski during Shirani's bond hearing Sunday.

"The defendant wrote four times in the e-mail that it was not a joke," Fialkowski said.

One of the e-mails was sent to a fairly senior official who reported the information to police and an investigation was immediately launched, said Mark Rosati, UIC Associate Chancellor for Public Affairs.

The senior logged on to a UIC computer at 1:14 p.m. Feb. 15 at a campus building in the 700 block of South Halsted Street, Fialkowski said.

At 2:36 p.m., Shirani sent an e-mail saying, "I am aiming to kill as many as I can ... after NIU, it's UIC's turn to face disaster," according to Fialkowski.

After campus police were notified, investigators traced the e-mail and identified Shirani’s user ID. Investigators also identified the computer where the e-mail originated as one on the campus building’s fourth floor, Fialkowski said. Video surveillance showed Shirani leaving the fourth-floor lab, she added.

Shirani signed a handwritten statement to UIC campus police that she wrote and sent the e-mail, Fialkowski said.

Shirani, of the 2000 block of West Roosevelt Road in Wheaton, faces one to three years in prison if convicted.

A campus-wide e-mail was sent Friday evening to inform students about the anonymous threat. In light of the Northern Illinois University shootings Thursday afternoon, campus police are taking any threats very seriously. Campus security was increased over the weekend, Rosati said.
