Twenty-three-year-old Maurice Wiggins was sentenced Monday in East St. Louis on a felony charge of making a bomb threat. He pleaded guilty in November.
Authorities contend Wiggins was upset about the break-up with his SIU-student girlfriend last August when he made the threat via 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.
Authorities say Wiggins also left a message with campus police, threatening to rape and kill 30 female students.
