Clery Crime Alert Burglaries The Department of Public Safety was informed of two burglaries that occurred this week. The first burglary occurred on Wednesday, September 10 at around 5:49 p.m.in 506 West 122 Street. The second burglary occurred on Tuesday, September 16 at around 11:30 a.m. in 150 Claremont Avenue. Both incidents appear to have been committed by the same suspect: a bald, male-presenting person, with a slim build, a medium complexion, wearing a dark sweater, blue jeans, grey sneakers, and carrying a black backpack. In both incidents the suspect appears to have buzzed multiple random apartments until they were let into the building. The suspect then takes packages from the lobbies and exits. No other information is available currently. If you have any additional information about this incident, please contact the Department of Public Safety at 212-854-2797. Safety Tips · Do NOT buzz people into your building if you do not know who they are. · Make sure the doors lock behind you every time to enter or exit a building. · Stay informed about delivery statuses and estimated arrival times. · Please try to retrieve your package in a timely manner. 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.

Message elements

How the first alert is built

To check this alert, SuperGrok Heavy 4.5 (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.

    Final assessment

    All 25 reads find Impact absent: lobby package theft restates the burglaries and does not state injury, danger, or other harm.

    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.
