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 the morning of Tuesday, May 2, 2023, Florida International University, the largest Hispanic-Serving Institution in the United States, was the highest-profile target of a coordinated swatting wave that hit at least five South Florida campuses in a single morning. FIU's alert system pushed an SMS reading 'A dangerous situation is occurring on or near campus! Evacuate the area NOW.' for AHC 3 (the Academic Health Center / College of Nursing) on the MMC main campus. Within roughly 30 minutes, FIU Police had cleared the building and posted publicly that the call appeared to be false. FIU Police Chief Alexander Casas called the hoax 'an incredible drain on resources.'

The 88-character SMS used FIU's standard 'dangerous situation' language template, deliberately vague on threat type to keep the message short, but prefixed with 'MMC Campus:' to scope the alert to the Modesto A. Maidique Campus in Miami
The SMS named no specific building, but a separate FIU Alert email reportedly cited 'possible shots fired at the College of Nursing building,' a discrepancy that students later criticized
Sent at approximately 9:30 a.m. EDT to FIU Alert subscribers, including students, faculty, and staff at the Modesto A. Maidique Campus (MMC) in Miami
The capitalized 'NOW' and the exclamation mark are preserved exactly as in the original WSVN-quoted alert

FIU Alert Update: This morning @FIUPOLICE received reports of an active shooter in AHC 3. Officers have cleared the building and are now conducting a methodical search. There is no danger to anyone on campus. The call appears to be false.

@FIU on X (verbatim raw t.co)x.comfind archived copies
Posted approximately 30 minutes after the initial SMS, a fast public clearance for a swatting incident at a campus the size of FIU
The tweet specifically named AHC 3 (the building), finally giving the building-specific information that the initial SMS had omitted
The phrasing 'methodical search' is notable; the language signaled that even after clearing the building, FIU PD was continuing a careful sweep rather than declaring full all-clear
The phrase 'the call appears to be false' was deliberately tentative, preserving the option to revise if something was found later

Message elements

How the first alert is built

To check this alert, Claude Opus 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.

MMC Campus: A dangerous situation is occurring on or near campus! Evacuate the area NOW. The activities on the east side of campus are isolated at this time. The west side of campus continues as normal.

    Final assessment

    Absent, unanimously. "MMC Campus" labels the location rather than the sender, and no agency or branded tag identifies who is writing.

    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.

    Final assessment

    Absent, unanimously. "A dangerous situation" is generic 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.

    Final assessment

    Present, unanimously. The message identifies MMC Campus and distinguishes the east side from the west side.

    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

    Present, unanimously. Recipients are directed to evacuate the area now.

    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.

  • Impactpresent25/25

    Final assessment

    Present, unanimously. Calling the situation dangerous conveys severity to people near the affected side of campus.

    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

Florida International University is a Carnegie R1 public research university in Miami serving roughly 56,000 students, the largest Hispanic-Serving Institution in the United States by enrollment. On the morning of Tuesday, May 2, 2023, FIU was the highest-profile target of a coordinated swatting wave that hit at least five South Florida campuses in a single morning: Florida Atlantic University, Palm Beach Atlantic, Indian River State, Everglades University, and FIU. FIU's alert system pushed an SMS at approximately 9:30 a.m. EDT reading 'A dangerous situation is occurring on or near campus! Evacuate the area NOW.' with a follow-up email naming the College of Nursing in AHC 3. FIU Police cleared the building within roughly 30 minutes. FIU Police Chief Alexander Casas told reporters: 'It is a hoax call and while some may think it's funny, it is not funny at all, it's an incredible drain on resources, first responders are somewhere they don't need to be where they could be doing other things that we should actually be doing.' The case is significant for the archive because (a) it documents the largest-HSI-in-the-country target in a coordinated South Florida swatting wave, (b) the official Twitter post quoted in this case is preserved as confirmed verbatim institutional alert text from a swatting incident, and (c) the SMS-to-email discrepancy (SMS gave no building, email named College of Nursing) drew criticism of FIU's multi-channel alert consistency at the time.
Analysis

Key Findings

FIU is the largest Hispanic-Serving Institution in the US, and the May 2, 2023 swatting was the highest-profile target in a coordinated five-campus South Florida wave
The 88-character initial SMS gave no building location, only a follow-up email cited the College of Nursing in AHC 3, a multi-channel inconsistency that later drew criticism
FIU Police cleared the building within roughly 30 minutes, fast for the largest HSI in the US
FIU's official Twitter update from May 2, 2023 is preserved in this case as confirmed verbatim alert text
FIU Police Chief Alexander Casas publicly characterized the hoax as 'an incredible drain on resources,' an unusually direct institutional statement against swatting
The case is part of a documented 2023 South Florida swatting wave that targeted multiple HSIs and minority-serving institutions in a single morning
Outcome
FIU Police cleared AHC 3 within approximately 30 minutes of the initial alert. No shooter, no victims, no weapon. Normal activities resumed about an hour later. Similar hoax calls hit Florida Atlantic University, Palm Beach Atlantic University, Indian River State College, and Everglades University the same morning. No suspect was publicly identified or arrested in connection with the FIU call at the time of the incident.
