We present a search for dilepton events from t{bar t} production with one electron or muon and one hadronically decaying {tau} lepton from the decay t{bar t}{r_arrow}(scr(l){nu}{sub scr(l)}) ({tau}{nu}{sub {tau}}) b{bar b}, (scr(l)=e,{mu}) , using the Collider Detector at Fermilab. In a 109 pb{sup {minus}1} data sample of p{bar p} collisions at {radical}(s)=1.8 TeV we expect {approximately}1 signal event and a total background of {approximately}2 events; we observe 4 candidate events (2 e{tau} and 2 {mu}{tau} ). Three of these events have jets identified as b candidates, compared to an estimated background of 0.28{plus_minus}0.02 events. {copyright} {ital 1997} {ital The American Physical Society}
