## Where it stands

**Most likely** Its tests partly supported it: two pieces of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- Particle types are consistent across the tie and are not laboratory or storage contamination.
- A named suspect with a matching work history exists.
- DNA on the tie or clip belongs to one dominant wearer.

## What would rule it out

- Evidence that the tie was not his (another passenger's, or planted), or that the particle load is post-1971 contamination.
