Crime Alert 2021-3: Home Invasion & Sexual Assault Summary: The Ann Arbor Police Department (AAPD) is actively investigating a home invasion and sexual assault that occurred in an off-campus neighborhood. The suspect entered through an unlocked exterior door in the bedroom while the victim was in bed sleeping. He got into the victim’s bed and started to touch her inappropriately. The victim screamed, and the suspect fled from the area in an unknown direction. If you have any information, please contact the Ann Arbor Police department, Detective Steven Van Alstine at 734-794-6930 ext 49317 or the Ann Arbor Police Department Tip Line (734) 794-6939 or tips@a2gov.org or the Division of Public Safety & Security at (734) 763-1131 Remember: - Keep all exterior doors and windows locked - Keep exterior lights on at night - If you see something, say something. Report suspicious behavior. Call 911 - Confidential Tip Line 1-800-863-1355 Sexual assault is any sexual activity that occurs in the absence of consent. Responsibility lies with the perpetrator, not the survivor – no one deserves, asks for, or provokes sexual assault. The University of Michigan Police Department has a Special Victims Unit that strives to provide a safe, caring environment where victims are empowered to take action. If you or someone you know has experienced sexual assault, we encourage you to report it to law enforcement. For status updates to this alert, visit our website and follow us on Twitter and Facebook.

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

    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 reports a "Home Invasion & Sexual Assault", specific crimes.

    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.

  • Locationpresent24/25

    Final assessment

    Present, by near consensus (24 of 25): "an off-campus neighborhood" is a general but stated area; one dissent wanted a named street or place.

    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: it tells recipients to "Keep all exterior doors and windows locked", keep exterior lights on, and call 911.

    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

    Absent, unanimously: it defines sexual assault but states no further danger or severity to recipients.

    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.
