Clery Crime Alert Stalking The Department of Public Safety has been informed of reported stalking occurring since September 2024 at both on and off campus locations. The incident was reported to Columbia University’s Department of Public Safety on Wednesday, November 20, 2024. The complainant did not wish to file a police report; however, the Department of Public Safety has made the police aware of this incident. The complainant, a Columbia University student, reported that they were approached by a non-affiliate at various locations, including the Starbucks at 2929 Broadway and at the Carman gate, on West 114th Street and Broadway. The subject depicted in the image below attempted to interact with the complainant. The Department is also aware that the subject has approached other community members. While the reported interactions have not been violent in nature, we want to ensure our community is aware and are encouraged to report any unwanted interactions to the Department of Public Safety by calling 212-854-2797. The subject is described as being, 5’8” – 6’ tall, with a medium build, a dark complexion, having mid to long curly black hair, and is usually wearing dark clothing and a baseball cap. They are known to frequent the Starbucks at 2929 Broadway. Safety Tips Trust your gut. If someone makes you feel uncomfortable or a conversation weirds you out, report it immediately. Not everyone on the street is a dangerous person, but the old adage of "stranger danger" always applies. Do not give out any identifying information to a stranger. If someone ignores your wishes to be left alone, or you are being followed, enter an open business or building and let an employee know that something is wrong. Stay inside until help arrives. If you are nearby campus, look for the Red Lion logo on a door or window. The Safe Haven program, organized by the Department of Public Safety, has screened more than 130 businesses near the Morningside, Manhattanville and Medical Center campuses. You can enter the building and ask an employee to phone Public Safety or the police and wait for security personnel to respond. DISCLAIMER: Clery Crime Alerts (Timely Warning Notifications) are distributed pursuant to the Jeanne Clery Disclosure of Campus Security Policy and Campus Crime Statistics Act. Columbia University is required to alert the campus community when certain crimes occur in our Clery Act defined campuses that represent a serious or continuous threat to the community.

For more information about Columbia University’ s Clery Act compliance efforts, please contact the Department’ s Clery Act Compliance Director, Roberto A. Pineda Sanchez at rp3240@columbia.edu.

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.

  • Impactabsent5/25

    Final assessment

    Majority finds impact absent; not violent in nature undercuts injury impact, while a minority cites Clery serious or continuous threat boilerplate.

    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.

    See all 25 individual reads
    1. absent: Stalking is named without separate severity or harm-to-people consequence wording.
    2. absent: The text states interactions have not been violent in nature, undercutting injury impact.
    3. absent: Impact is absent beyond naming stalking and unwanted approaches.
    4. present: Clery disclaimer says serious or continuous threat to the community, which is severity language.
    5. absent: Approaches and attempted interactions are events, not stated injury or danger consequences.
    6. absent: No line states injuries, assault, or life-threatening outcomes.
    7. absent: Impact element fails under a strict reading that hazard names alone do not count.
    8. present: Serious or continuous threat in the Clery notice conveys community-level impact.
    9. absent: Not violent in nature is explicit non-violence, not impact severity for people.
    10. absent: No injuries, no weapon, and no physical harm phrase appear in the body.
    11. absent: Suspect description is identification detail, not impact severity language.
    12. absent: Naming stalking does not by itself satisfy impact under the rubric.
    13. present: The disclaimer frames the crimes as a serious or continuous community threat.
    14. absent: Impact is not conveyed with words like dangerous, life-threatening, or may cause harm.
    15. absent: The body reports what happened without stating severe outcomes for people.
    16. absent: Unwanted interactions describe the hazard pattern, not impact severity.
    17. absent: Strict rubric: hazard labels without consequence language yield I absent.
    18. present: Serious or continuous threat language can be read as explicit community impact.
    19. absent: No secondary effects such as injuries treated or property damage appear.
    20. absent: The alert stops short of stating what the hazard could do beyond naming it.
    21. absent: Consequence language for people is missing outside the crime type name.
    22. absent: Impact absent: no severity adjective and no harm-to-people clause beyond not violent.
    23. present: Clery serious or continuous threat clause states why the community faces impact.
    24. absent: Stalking name alone does not equal impact under the rubric.
