We have searched supersymmetry (SUSY) using trilepton events in p{bar p} collisions at {radical}s = 1.8 TeV. In the Minimal Supersymmetric Standard Model (MSSM), trilepton events are expected from chargino-neutralino ({tilde {chi}}{sub 1}{sup {plus_minus}}{tilde {chi}}{sub 2}{sup o}) pair production, with subsequent decay into leptons. In all possible combinations of electron and muon channels in 19 pb{sup {minus}1}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({tilde {chi}}{sub 1}{sup {plus_minus}}{tilde {chi}}{sub 2}{sup o}) < 46 GeV/c{sup 2} for -500 < {mu} < -400 GeV, 2.0 < tan {beta} < 15.0, and M({bar q}) = 1.2 {times} M({bar g}).
