No ones knows how long 20-year-old Nicholas Barnes lay dead in his dorm room before he was discovered. 

In fact, it was complaints from other students about a foul smell coming from Barnes' room that lead to his discovery, suggesting the body had been there for some time. 

The university indicated that there was no sign of foul play, the Chicago Tribune reports, but a cause of death has not been determined yet.
