Every call leaves a trace. Only one location matches every detail.
Each case begins with a 9-1-1 call from someone being held at an unknown location. They can’t give an address — only what they noticed on the way: a partial street sign, a ZIP code, a door number, a color, a sound. Read the transcript, extract every usable clue, and filter 200 deliberately similar records until one location is left standing.
Apartments, houses, farms, inns, boats and RVs — every location type brings a different set of clues.
