Suspect(s) Description The subject was described as a brown-skinned male, approximately 5’4″ to 5’6″ in height. Witnesses could not identify specific facial features or the exact race due to the subject wearing a black ski mask concealing his entire face.

The tips are general and have no relation to this specific incident. Know where the emergency call boxes are on campus and learn how to use them. If you are being followed, change direction and go to the nearest business or home; knock on the door, and request that someone call the Police. Note the description of the person following you.

Final assessment
behind Porter B, near the Provost House is a named 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
Recipients are told to contact UCPD or the tip line and are given personal safety tips.
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
Naming knife brandishing is the hazard; there is no extra severity language such as dangerous.
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.
