Police spokesman Anthony Guglielmi says campus security and an off-duty city officer responding to a call for a suspicious person heard screams to call police around 1:20 a.m. Tuesday in the 300 block of University Parkway.
Guglielmi says the student told a man he found inside his garage to leave and the man accosted him. That's when Guglielmi says the student defended himself, cutting off the man's hand and causing a severe laceration to his upper body.
He says the man died on the scene, but police are not yet releasing his name.
Police are interviewing the student and his three roommates and are talking to prosecutors about whether to file charges.
