# A coordinated campaign by a foreign state or other actor against people with access to US secrets

Some or all of the deaths and disappearances are the work of a coordinated campaign, by a foreign state or another actor, against people with access to US nuclear, space or defence secrets.

**Still possible** Answers **1** question0

## Where it stands

**Still possible** One piece of evidence for, five against. It needs two reviews to be accepted.

## What it predicts

- The victims had access to related secrets that a foreign service would want.
- Investigators find signs of targeting: surveillance, approaches, tampering, or a shared method across cases.
- The FBI's review or a counter-intelligence finding names an actor.

## What would rule it out

- Each case is closed with a local cause and no shared actor.
- The people on the list had no access in common, or no access worth targeting.
