  We consider the possibility that the dark matter particle is a scalar WIMP
messenger associated to neutrino mass generation, made stable by the same
symmetry responsible for the radiative origin of neutrino mass. We focus on
some of the implications of this proposal as realized within the
singlet-triplet scotogenic dark matter model.We identify consistent parameter
sets consistent both with neutrino mass and the observed dark matter abundance.
Finally we characterize the expected phenomenological profile of heavy Higgs
boson physics at the LHC as well as at future linear Colliders.
