The search for signals from Supersymmetry at hadron colliders has largely been centered on the search for squark and gluino production, usually through events with large missing transverse energy (E{sub t}). A promising alternative at the Tevatron is the search for production of the lightest chargino ({tilde W}{sub 1}) and next-to-lightest neutralino ({tilde Z}{sub 2}), with the assumptions that R-parity is conserved and the lightest neutralino ({tilde Z}{sub 1}) is the lightest supersymmetric particle (LSP). Although the mass limit established by LEP experiments, {sup 2}M{sub {tilde W}1} >45 GeV/c{sup 2}, excludes the on-shell process {anti p}p {yields} W{sup {+-}} {yields} {tilde W}{sub 1} + {tilde Z}{sub 2}, the off-shell process W{sup {+-}} {yields} {tilde W}{sub 1}{tilde Z}{sub 2} can have a sizeable rate due to large WW{tilde W}{sub 1}{tilde Z}{sub 2} coupling. Here, the status of a search for the pair production of the lightest chargino and second lightest neutralino states of the minimal supersymmetric model is presented. The authors searched for four tri-lepton final states: eee, ee{mu}, e{mu}{mu}, and {mu}{mu}{mu}, all with missing transverse energy.
