Clery Crime Alert Burglaries Columbia University Public Safety was recently informed that on Sunday, November 2, 2025, between 3:43 p.m. and 3:45 p.m. two Burglaries occurred at 195 Claremont Avenue and 549 Riverside Drive. Both incidents appeared to have been committed by the same suspect, a male-presenting person, with a slim build, dark complexion, gray beard, wearing dark framed glasses, a dark jacket, a black beanie with NY in white lettering, and dark jeans, carrying a Fresh Direct NY Yankees tote bag. They entered 195 Claremont Avenue by piggybacking behind tenants entering the building. Once inside, they were able to access 549 Riverside Drive. The same suspect was involved in the incidents outlined in the Alert sent out on October 22, 2025. 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. Harm Reduction Strategies When safe and if possible, do not allow others to piggyback behind you when you are entering your apartment building. If you do not feel safe stopping a person from piggybacking behind you, you can always call Public Safety (212-854-2797) once you are in a safe location. 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 and try to retrieve your package in a timely manner. Many mail carriers (UPS, Fed Ex) have offices where you can drop-off and pick-up your packages safely. You can also arrange delivery to partnered local businesses, like pharmacies. DISCLAIMER: Clery Crime Alerts (Timely Warning Notifications) are distributed pursuant to the Jeanne Clery Disclosure of Campus Security Policy and Campus Crime Statistics Act.

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.

    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

    All 25 reads find Location present: 195 Claremont Avenue and 549 Riverside Drive.

    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.

    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.

  • Impactabsent0/25

    Final assessment

    All 25 reads find Impact absent: naming the burglaries states the completed thefts without injury, danger, or other severity.

    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.
