A Chicago man faces up 10 years in federal prison after admitting that he threatened to bomb Southern Illinois University's flagship Carbondale campus and kill 4,000 students and staff.

Twenty-3-year-old Maurice Wiggins pleaded guilty Thursday in Benton to a felony charge of making a bomb threat.

Authorities allege that Wiggins made the threat via the Internet on Aug. 29, sending a message from his cell phone to the 20,000-student university's crime-watch website.

Wiggins allegedly said he planned to bomb three dormitories and a student center.

Wiggins also faces up to $250,000 in fines when sentenced Feb. 27 in East St. Louis.
