  In models where supersymmetry breaking is communicated into the visible
sector via gauge interactions the lightest supersymmetric particle is typically
the gravitino which is too light to account for cold dark matter. We point out
that the lightest messenger sneutrinos with mass in the range of one to three
TeV may serve as cold dark matter over most of the parameter space due to
one-loop electroweak radiative corrections. However, in the minimal model this
mass range has been excluded by the direct dark matter searches. We propose a
solution to this problem by introducing terms that explicitly violate the
messenger number. This results in low detection rate for both direct and
indirect searches and allows messenger sneutrinos to be a valid dark matter
candidate in a wide region of SUSY parameter space.
