Explores how gamified OSINT contests help locate missing people, covering the roles of participant, coach and report writer, plus practical search tactics.
Summary
A Trace Labs panel looked at how gamified open-source intelligence is used to find missing people. The moderator, a Trace Labs director, was joined by a participant who had won the top individual prize, a long-time coach, and the team lead for reporting. They described the workflow: participants search during timed capture-the-flag events, coaches review submissions and award points, and the reporting team later packages the findings for law enforcement, with the goal of giving families answers.
Much of the discussion focused on method. Each discovered detail should be treated as a pivot toward the next lead. Teams benefit from clear notes and from agreeing on skills early, since a member without social media can still contribute through documentation or public records. Panelists warned about the wrong-person trap: when investigators fixate on a candidate, they should actively try to disprove the match. Narrowing search dates to the period before someone vanished can cut through news noise, and relatives named on missing-person posters often lead to new material.
The speakers also stressed the human side. The work can surface disturbing material, so participants should know when to step back and talk to their team. They noted that many people keep a public account and a private one. Their advice for newcomers was to start with search engines and free online videos, examine your own digital footprint first, and learn by doing. A single verified fact can be the missing piece that investigators need.
