  We provide a detailed analysis of the supersymmetric tri-lepton signals for
sparticle searches at the Tevatron in the minimal supersymmetric standard model
with general CP-violating phases but without flavor mixing among sfermions of
different generation. The stringent experimental constraints on the
CP-violating phases from the electron and neutron electric dipole moments are
included in the analysis for two exemplary scenarios of the SUSY parameters;
one with decoupled first two generation sfermions and the other with
non-decoupled sfermions. In both scenarios, the production cross section and
the branching fractions of the leptonic chargino and neutralino decays are
sensitive to CP-violating phases. The production-decay spin correlations lead
to several non-trivial CP-even observables such as the lepton invariant mass
distribution and the lepton angular distribution, and several interesting T-odd
(CP-odd) momentum triple products. The possibility of measuring the
CP-violating phases directly through those T-odd observables is investigated in
detail.
