Crime Alert 2023-01: Sexual Assault & Indecent Exposure Summary: The University of Michigan Police Department (UMPD) is actively investigating two indecent exposure incidents and a sexual assault (groping) that occurred on North Campus. At approximately 4:30 p.m., a female student reported that while walking on the sidewalk near parking lot NW10, an unknown male approached her while stimulating himself with his genitals exposed. He was last seen leaving the area in a black or dark blue colored sedan. A short time later, another female student reported that while walking in the same area, she observed a male looking at her from a vehicle. As she got closer, she saw the suspect exit the car with pants around his knees. He approached her with his genitals exposed while stimulating himself. As the student walked by, she observed the suspect return to his vehicle and leave the area in a light yellow or silver sedan. At approximately 8:30 p.m., UMPD received a report of a sexual assault that happened around 3:30 p.m. A suspect approached a female student from behind while she was walking on the sidewalk near parking lot NW10. He groped her through her clothing. She struck him with her umbrella across his face. At this stage, all incidents are believed to have been perpetrated by the same individual. If you have information regarding these incidents, please contact UMPD at 734-763-1131 or Detective John Buehler at jbuehler@umich.edu. Suspect(s) (as described by the victims): (1) White male in his 20s, medium build, wearing a sky-blue t-shirt with no graphics (2) White male, approximately 6 feet tall, full beard, long wavy brown hair (3) White male, mid 20’s-30, 5’8-5’9, skinny to medium build, short curly red hair, blue eyes, goatee/mustache, bright t-shirt or polo shirt, no hat or glasses Remember: - Trust your intuition. If a particular situation makes you feel uncomfortable or unsafe, choose an alternative. - If you see something, say something. Report suspicious behavior. Call 911 - Walk with a trusted friend or co-worker when possible - Confidential Tip Line 1-800-863-1355 Sexual assault is any sexual activity that occurs in the absence of consent. The 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

    All 25 reads agree the source is present: "The University of Michigan Police Department (UMPD)" is named as investigating.

    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

    Unanimous: the alert names "two indecent exposure incidents and a sexual assault (groping)", 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.

  • Locationpresent25/25

    Final assessment

    All 25 reads find a location: the incidents occurred "on North Campus" near parking lot NW10.

    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

    Unanimous: the Remember list tells recipients to "Walk with a trusted friend or co-worker when possible" and to trust their intuition.

    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.

  • Impactabsent2/25

    Final assessment

    Absent by strong consensus (23 of 25): the acts are described but no injury or explicit severity is stated. Two reads treated "groped her through her clothing" as a stated harm.

    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.
