Pedestrian tunnel under Campus Drive
campus
Affidavit / Hull path: after 11:50 the flag-shirt figure stopped at stairs, pulled a phone at 11:53, then went down into the tunnel toward a parking-garage stairwell.
This is a path node, not a crime scene. FBI stills of a garage stairwell are the public pictures. Pin is campus-approximate next to the garage record, not a surveyed tunnel mouth.
