Even tetrahedron count conjecture for tetrahedral link complements

A tetrahedral link complement is a link complement that admits a tetrahedral tessellation; the corresponding combinatorial tetrahedral tessellation has a well-defined number of tetrahedra.

Evenness conjecture. Every tetrahedral link complement has an even number of tetrahedra; equivalently, a corresponding combinatorial tetrahedral tessellation has an even number of tetrahedra.

The claim is suggested by the census data for tetrahedral manifolds and links. The supplied text gives no resolution of the conjecture.
