In a preliminary analysis, we have looked for evidence of the production and decay of SUSY chargino-neutralino (often referred to as Wino-Zino) pairs into the trilepton events using 11.1 pb{sup {minus}1} of p{bar p} collision data at {radical}s = 1.8 TeV collected in 1992--1993 by CDF. Using all possible electron and muon decay channels, we observe two events which pass our trilepton criteria. Assuming, for the purposes of a conservative limit, that these events are all signal events, we exclude a point in the parameter space of the Minimal Supersymmetric Standard Model (MSSM) which corresponds to the limit of sensitivity of LEP measurements. Systematic errors have not been included in the result. Larger data samples and a more careful treatment should allow a large region of MSSM parameter space to be explored using the trilepton channel.
