But the Bluetooth pairing history on the camera tells a different story. It was last paired with a phone — and that phone broadcast a public Wi-Fi probe request, the kind every smartphone emits automatically when searching for known networks. The probe contains a partial network name: "Ida_H_5G".
A name. A home network. A person.
You cross-reference it against LinkedIn, public records, the digital footprints people leave without knowing. Twenty minutes later you have a face.
Ida Hartmann. Twenty-nine. Freelance photographer with a portfolio of architectural and documentary work. Currently listed as working on a long-term project called "The Unseen City" — photographing Copenhagen infrastructure, service corridors, utility spaces.
Legitimate cover, or an actual photographer who has been used by someone who knew her access routes.
Either way, she is the thread. And she is currently showing as active on Instagram, posting from what the geotag suggests is a café on Istedgade, twelve minutes walk away.
