Learn Humanitarian OSINT Method

Missing Persons

Humanitarian OSINT — the Trace Labs model — finds actionable leads on missing people from public sources and hands them to law enforcement and families. It never contacts the subject and never draws conclusions; it produces verified leads. Post-conflict family reunification is a major and growing use.

Humanitarian OSINT, popularized by the Trace Labs model, mobilizes ethical investigators to find actionable leads on missing people using only public, openly available information.

The output is never a verdict or a confrontation. Analysts gather and verify leads, then hand them to law enforcement and the families and NGOs supporting the case. They never contact the subject and never act on their own.

Post-conflict family reunification — reconnecting people separated by war or disaster — is one of the largest and fastest-growing uses of this method, always anchored in authorized, public-data-only work.

Scope is authorized and ethical, public data only.

Goal is actionable leads handed to police.

Never contact the subject; never act alone.

Read the implementation

Connect each part of the code to the concept before you type.

1. Authorized scope

Humanitarian OSINT is done only within an authorized, ethical scope — no unsanctioned probing.

scope: authorized-and-ethical

2. Goal is leads

The deliverable is actionable leads for law enforcement, never a conclusion or an arrest the analyst makes.

goal: actionable-leads-to-police

3. Public sources only

Only public social posts and media are used; no breaking in, no private data.

sources: public-social-and-media

4. Last-seen first

Work outward from the last confirmed sighting into the person's public network.

method: last-seen-then-network

5. Hand off

Findings are packaged into a report and handed to the professionals working the case.

handoff: report-to-authorities

A complete learning loop

Understand

Read the concept map and follow the code breakdown.

Reconstruct

Type the implementation, repair mistakes and work through every recall exercise.

Verify

Use the final check without hints; revisit weak concepts in short practice sessions.
