The latest about an online threat that led the University of Chicago to cancel classes on Monday (all times local):

9:45 a.m.

Tyler Kissinger says as soon as people heard that the University of Chicago was shutting down because of an online threat of gun violence they closed their books, shut down laptops and hurried home.

Kissinger is the student body president. He was working at a campus coffee shop on Sunday night when the manager told him to start closing up and go home.

Kissinger says students haven't been given details about why the school was closed Sunday night and remained closed Monday.

The school canceled all classes and activities following the threat, which was passed on by the FBI and mentioned the quad and 10 a.m. Monday.

He called the threats a reminder that residents in the neighborhoods around the campus, which is on the South Side of Chicago, live with the threat of gun violence every day.

Kissinger says he only recalls the school being closed once before — because of weather.
