We present a search for dilepton events from tt̅ production with one electron or muon and one hadronically decaying τ lepton from the decay tt̅ →(ν)(τντ)bb̅ , ( = e,μ), using the Collider Detector at Fermilab. In a 109pb-1 data sample of pp̅ collisions at s = 1.8TeV we expect 1 signal event and a total background of 2 events; we observe 4 candidate events ( 2eτ and 2μτ). Three of these events have jets identified as b candidates, compared to an estimated background of 0.28±0.02 events.
