Confirmed HoaxDetermined to be a hoax. The institutional response is documented because it reveals how the alert system performed under a perceived real threat.

On September 13, 2022, Northeastern University employee Jason Duhaime staged a hoax explosion in the Immersive Media Lab at Holmes Hall on the Boston campus, triggering evacuations of multiple buildings, bomb squad deployments, and campus-wide emergency alerts. Duhaime, 45, called 911 claiming he was injured by sharp objects expelled from a hard plastic case. Investigators later found the case was empty and undamaged, and a word-for-word copy of the threatening letter was found on his computer, created just hours before the incident.

INITIAL ALERTSMS
Verified verbatimNU Alert text quoted verbatim in The Huntington News and attributed to the Northeastern University Police Department's Safety Notifications archive108 chars
Emergency services responding to an incident at Holmes Hall. Please avoid the area during the investigation.
Verbatim from the NU Alert message sent at approximately 7:55 PM EDT on September 13, 2022, as reported by The Huntington News and confirmed via the NUPD Safety Notifications archive.
The alert identified 'Holmes Hall' and instructed avoidance 'during the investigation', conspicuously not calling it an 'explosion,' unlike some media reports; the word 'incident' was used.
Duhaime called 911 at approximately 7:00 PM EDT on September 13, 2022; the first NU Alert arrived approximately 55 minutes later
Multiple subsequent campus-wide alerts were issued throughout the evening as bomb squads responded and buildings were evacuated
UPDATESMS
Verified verbatimNU Alert text quoted verbatim by The Huntington News (Northeastern's student newspaper) in its live coverage of the September 13, 2022 incident134 chars
Evening classes in Behrakis, Shillman, Ryder, Kariotis, Dockser, and West F are canceled due to the ongoing investigation in the area.
Names six specific buildings near Holmes Hall (Behrakis, Shillman, Ryder, Kariotis, Dockser, and West F) whose evening classes were canceled
The message frames the cause as 'the ongoing investigation in the area' rather than an explosion or bomb, consistent with NU Alert's restrained wording throughout the night
Reported by The Huntington News as roughly the third NU Alert of the evening; NEU sent multiple NU Alerts before issuing a fifth around 11:30 PM EDT
FOLLOW-UPSMS
Verified verbatimNU Alert text quoted verbatim by The Huntington News (Northeastern's student newspaper) in its live coverage of the September 13, 2022 incident77 chars
At this time, we expect the campus to be open and fully operational tomorrow.
Verbatim from the fifth NU Alert of the night, sent around 11:30 PM EDT on September 13, 2022, and quoted word-for-word by The Huntington News
Rather than an explicit all-clear lifting restrictions, the final message of the night reassured the community that campus would resume normal operations, consistent with NU Alert's measured wording throughout the incident
At the time, the incident was still being treated as a genuine explosion; it was not until October 4, 2022, that the hoax was publicly confirmed with Duhaime's arrest
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.

Emergency services responding to an incident at Holmes Hall. Please avoid the area during the investigation.

  • Sourcepresent14/25

    Final assessment

    A majority (14 of 25) finds the element is present: a slim majority (14 of 25) counts the named responding emergency services as a source, though dissenters note no actual sender, brand, or issuing authority is given.

    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

    All 25 reads agree the element is absent: it refers only to an incident and names no specific hazard.

    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 agree the element is present: it locates the incident at Holmes 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

    All 25 reads agree the element is present: it instructs recipients to avoid the area during the investigation.

    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.

    Final assessment

    All 25 reads agree the element is absent: no clock time, date, or recency cue appears.

    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.

  • Impactabsent0/25

    Final assessment

    Absent by unanimous agreement; an incident response with an avoid-the-area instruction names no hazard and states no harm or potential 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

On the evening of September 13, 2022, Jason Duhaime, the Director of Northeastern University's Immersive Media Lab, called 911 to report that he had been injured by sharp objects expelled from a hard plastic case he opened in the lab at Holmes Hall. The reported explosion triggered a massive emergency response, including evacuations of multiple campus buildings, deployment of two law enforcement bomb squads, and numerous campus-wide alerts. Evening classes in nearby buildings were canceled. However, investigators quickly observed that the case described by Duhaime was empty and undamaged, and neither the case nor the threatening letter showed any indication of exposure to an explosive discharge. A forensic examination of Duhaime's computer revealed a word-for-word electronic copy of the anonymous threat letter, with metadata showing it was created at 2:57 PM EDT and last printed at 4:02 PM EDT on September 13, just hours before he reported the incident. Duhaime was arrested on October 4, 2022, in San Antonio, Texas, and was convicted of conveying false and misleading information related to an explosive device and two counts of making materially false statements. The case highlighted the significant resources consumed by hoax incidents and the disruption they cause to campus communities.
Analysis

Key Findings

The hoax was staged by a university employee, not an outsider, demonstrating that insider threats can be as disruptive as external ones
Forensic evidence on Duhaime's computer revealed he created the threatening letter just hours before staging the incident
The incident triggered a massive multi-agency response including two bomb squads, multiple building evacuations, and class cancellations
Outcome
Jason Duhaime was arrested on October 4, 2022, in San Antonio, Texas. A federal jury convicted him in June 2024 of conveying false and misleading information related to an explosive device and making materially false statements to a federal law enforcement agent. On January 13, 2025, he was sentenced to one year and one day in federal prison.
