 class in Room 204 in the Norris Hall during April 2007, held the door of his classroom shut while Cho attempted to enter it. Although he was shot through the door, Librescu managed to prevent the gunman from entering the classroom until most of his students had escaped through the windows. He was struck by five bullets, with a shot to the head proving to be fatal. Of the 23 registered students in his class, only one, Minal Panchal, died.

A number of Librescu's students have called him a hero because of his actions. Caroline Merrey, a senior, said she and about 20 other students scrambled through the windows as Librescu shouted for them to hurry. Merrey said, "I don’t think I would be here if it wasn't for [Librescu]." Librescu's son Joe said he had received e-mails from several students who said he had saved their lives and regarded him as a hero. Also, Librescu's page on RateMyProfessors.com has turned into a memorial for the professor.
