The production of chargino-neutralino pairs and their subsequent leptonic decays is one of the most promising supersymmetry (SUSY) signatures at the Tevatron proton-antiproton collider. We present here the most recent results on searches for the three-lepton and missing-transverse-energy SUSY signature using data collected at the Tevatron. The results are interpreted within the minimal supergravity (mSUGRA) scenario. Also presented is a search for R-Parity violating supersymmetry in which signals of possible non-conservation of R-parity through resonant production of supersymmetric neutrinos which decay to a pair of leptons.
