UnfoundedNo evidence of an actual threat was found. The institutional response is documented because the alert communication is identical to what would occur during a real incident.

On October 27, 2016, an anonymous caller described as intoxicated made a bomb threat to the Registrar's Office at Columbia College Chicago, prompting the Office of Campus Safety and Security and the Chicago Police Department to evacuate the fifth through seventh floors of 600 S. Michigan Avenue and deploy a canine unit for a search. No explosive device was found, and no injuries were reported. The incident was not the last bomb threat the downtown arts school would receive.

Please remain clear of the fifth through seventh floor until all clear message is given.
The bomb threat was phoned into the Registrar's Office by an anonymous caller whom campus safety described as intoxicated
The evacuation targeted only floors 5 through 7 of 600 S. Michigan, the building that houses the Registrar among other administrative offices, rather than triggering a whole-campus evacuation

Message elements

How the first alert is built

To check this alert, Claude (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

Please remain clear of the fifth through seventh floor until all clear message is given.

    Unanimous absent. No sender tag, university name, or issuing authority appears anywhere in the message.

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardabsent0/25

    Final assessment

    Unanimous absent. The message only references an all clear and never names the actual threat such as a bomb.

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

  • Locationpresent25/25

    Final assessment

    Unanimous present. All reads cite a specific location, the fifth through seventh floor.

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Guidancepresent25/25

    Final assessment

    Unanimous present. Every read finds a protective instruction telling recipients to remain clear of those floors.

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

  • Timepresent23/25

    Final assessment

    Present by strong majority. Most reads treat until all clear message is given as a duration cue, while a small minority calls it a condition rather than a time reference.

    When the message applies. A timestamp, the word now or immediately, or a phrase like until further notice tells the reader whether the danger is current and how quickly to act.

    See all 25 individual reads
    1. present: The phrase until all clear message is given conveys an until further notice recency cue.
    2. present: It uses "until all clear message is given," conveying duration similar to until further notice.
    3. present: It says "until all clear message is given", a recency cue indicating duration.
    4. absent: No clock time, date, or recency word appears; "until all clear" is conditional not a time cue.

    6. present: It says until all clear message is given, a recency or duration cue.

  • Impactabsent0/25

    Final assessment

    Absent unanimously across all 25 reads. The message asks people to remain clear of certain floors until an all-clear but states no hazard, harm, or consequence.

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.

About this analysis
Context

Background

Columbia College Chicago is a private arts and media college in the South Loop neighborhood of Chicago, enrolling roughly 8,000 students in film, music, journalism, fashion, theater, and fine arts programs. Its main building at 600 S. Michigan Avenue sits on Chicago's lakefront museum campus strip. On October 27, 2016, an anonymous caller who was described as intoxicated phoned the Registrar's Office with a bomb threat, triggering an evacuation of the fifth through seventh floors and a canine search by the Office of Campus Safety and Security and the Chicago Police Department. No device was found and no one was arrested. The 2016 incident foreshadowed a second bomb threat in July 2018, when an emailed threat alleged that bombs had been placed 'around' the campus and were set to detonate the following evening; in that case the college remained open while police investigated. The archive includes both threats to document the pattern of hoax bomb threats directed at arts and media institutions in the post-2015 wave. The October 2016 case is notable for the phone-call delivery method and the partial-floor evacuation response, contrasting with the 2018 email threat that produced no evacuation at all.
Outcome
The canine search of the fifth through seventh floors of 600 S. Michigan Avenue found no explosive device. No injuries were reported and no one was taken into custody.
