Dear Members of the Lehigh Community, We wanted to make the community aware of reports received over the past two days regarding a non-Lehigh community member trespassing in Lehigh residence halls. This individual gained access by following student residents with ID access into the residence halls. After further investigation, Lehigh police determined that the suspect left without further incident and appeared to have gained access, walked around, and then immediately left the residence hall. The Lehigh University Police Department (LUPD) has identified the adult individual, who is not affiliated with Lehigh, and today, the individual is being charged with criminal trespass. Lehigh police have been in direct contact with the individual and their immediate family to resolve the trespassing incidents. Lehigh police also have followed up with the students who reported these incidents. We wanted to take this opportunity to additionally remind members of the campus community of the following general safety reminders: -Please remember to never prop open building doors. While it may seem polite, never hold a door to allow others to enter a building behind you without swiping their ID card to gain access. -Remain alert and be aware of your surroundings at all times. If you notice someone following you or notice that someone gained unauthorized access to a campus building or residence, contact the LUPD at 610-758-4200. -For students living in the residence halls, never leave your door unlocked. Even though residence halls are accessible only by card access, if someone gains unauthorized access, keeping your door locked provides additional security. -Regardless of where you live, secure all doors and windows and keep your residence locked at all times. -Education is an important facet of campus safety. Read more safety tips on the LUPD website: https://campussafety.lehigh.edu/content/safety-tips Thank you, and if you have any questions about these tips or additional safety information, our Division of Campus Safety is available to assist you at 610-758-4200.

Message elements

How the first alert is built

To check this alert, Claude Opus 5.5 (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

    Present, unanimously: the notice names the Lehigh University Police Department (LUPD) and is signed by Chief Jason Schiffer.

    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.

  • Hazardpresent25/25

    Final assessment

    Present, unanimously: it names a non-community member "trespassing in Lehigh residence halls" by following students in.

    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

    Present, unanimously: the incidents occurred in "Lehigh residence halls".

    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.

  • Guidancepresent25/25

    Final assessment

    Present, unanimously: readers are told never to prop doors, to keep doors locked, and to contact LUPD if followed.

    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.

  • Timepresent25/25

    Final assessment

    Present, unanimously: it refers to reports "over the past two days" and charges filed "today".

    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, unanimously: the suspect "left without further incident" and no potential harm or severity is stated.

    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.
