We search for supersymmetry (SUSY) using trilepton events in {ital p{anti p}} collisions at {radical}s = 1.8 TeV. In the Minimal Supersymmetric Standard Model (MSSM), trilepton events are expected from chargino-neutralino ({anti {chi}}{sub 1}{sup {+-}}{anti {chi}}{sub 2}{sup 0}) pair production, with subsequent decay into leptons. In all possible combinations of electron and muon channels in 100 pb{sup -1} of data, we observe no events which pass our trilepton selection criteria. Assuming the GUT hypothesis within the framework of the MSSM, our preliminary analysis excludes M({anti {chi}}{sub 1}{sup {+-}}) < 68 GeV/c{sup 2}.
