At approximately 6:00 AM on Monday, May 22, 2023, Harvard University Police Department (HUPD) officers responded to a report of an aggravated assault. Upon officers’ arrival, a victim reported that while walking on Gordon Road, towards Shad Hall, they passed an unknown male suspect yelling obscenities. Moments later, the suspect returned to the area wielding a screw driver, lunged at the victim, and threatened to kill them. The victim was not injured during the assault and de-escalated the situation until the suspect fled the immediate area. Officers conducted a search of the surrounding area for the suspect with negative results. The suspect is described as a White male, 28 to 35 years old, approximately 5’5” tall, medium build, red beard, last seen wearing a blue hoodie, khaki pants, blue baseball cap, khaki shoes, with a black backpack and blue bag. The HUPD is actively investigating this aggravated assault and increasing high visibility patrols in and around campus. If anyone has information regarding this incident, please contact the Harvard University Police Department’s Detective Bureau at 617-495-1796. If at any time, you observe any type of suspicious activity or experienced a violent offense, please notify the Harvard University Police Department immediatelyat 617-495-1212 (Cambridge Campus) or 617-432-1212 (Longwood Campus.) Students, faculty, staff, and visitors are encouraged to store the HUPD’s urgent number in their phone. If you have experienced harm or been the victim of a crime, and would like information on available resources both on and off campus, please visit www.hupd.harvard.edu/personal-and-violent-crime. The Harvard University Police Department wants to remind students, faculty, staff, and visitors that we are located in a thickly settled area and share many of the crime and safety issues that exist in any city. Community members should be vigilant while walking throughout campus and surrounding areas both during the day and at night, and to take the appropriate precautions, such as walking with others and utilizing walking escorts, taxi escorts (Longwood campus), the shuttle bus, and evening van services whenever possible. Students, faculty, staff, and visitors also may call the Harvard University Police Department at 617-495-1212 if they believe they are in danger while waiting for transportation. Additional safety, escort, and transportation information can be found at www.hupd.harvard.edu/your-role-staying-safe. If you suspect you are being followed, stay away from dimly lit areas and head for a building that you know to be open. Trust your instincts. If you feel uncomfortable about someone near you, head for a populated area and call the Harvard University Police Department. For more detailed information on safety and security, please read the Harvard University Police Department's Annual Security Report, which can be found at www.hupd.harvard.edu/annual-security-report. For questions about this advisory, please contact the Harvard University Police Department's Public Information Officer, Steven G.

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.

    Final assessment

    Unanimous: the alert specifically describes an aggravated assault involving a suspect wielding a screwdriver and a threat to kill.

    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.

    Final assessment

    Unanimous: the alert names the specific location, Gordon Road toward Shad Hall.

    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.

    Final assessment

    Nearly unanimous (24 of 25): the alert instructs protective steps such as walking with others, using escorts, and calling HUPD if followed; one read missed this and is an outlier.

    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.

  • Impactpresent21/25

    Final assessment

    Most reads count the suspect's explicit threat to kill and lunge at the victim as a stated severity of harm; a minority focused only on the victim not being injured, but the majority reading of a stated death threat prevails.

    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

In the pre-dawn hours of May 22, 2023, HUPD officers responded to an aggravated assault near Harvard Business School in the Allston neighborhood of Boston. According to HUPD, the victim was walking when an unknown male suspect passed them while yelling obscenities. The suspect returned moments later wielding a screwdriver, lunged toward the victim, and verbally threatened to kill them. The victim de-escalated the encounter and the suspect fled. No physical injuries were reported. Because the suspect remained at large and the encounter took place within Clery-reportable geography, HUPD issued a Clery timely warning that morning under the standard categories of aggravated assault. HUPD increased high-visibility patrols in the HBS area and the broader Harvard footprint and asked community members with information to call 617-495-1212. The case is one of several screwdriver-related threats reported on Boston-area campuses during 2023, including a similar incident at the University of Hawaii at Manoa in 2025.
Analysis

Key Findings

The incident is one of the few documented Clery timely warnings issued by HUPD for an aggravated assault in 2023
Despite no injuries to the victim, HUPD treated the threat as Clery-reportable because of the deadly weapon and the explicit homicide threat
The timely warning remains listed on the HUPD website, though the exact wording documented here is a reconstruction
Outcome
The suspect fled and was not immediately apprehended. HUPD increased high-visibility patrols around HBS and Allston. The victim de-escalated the encounter and was not physically injured.
