traceless
Without any evidence
Traceless means leaving no trace—no evidence, residue, or sign of presence.
A traceless disappearance offers investigators nothing to follow.
In mathematics and physics, traceless describes a matrix whose diagonal elements sum to zero.
The word emphasizes completeness: not merely hard to track, but impossible.
