We report on a search for a high mass, narrow width particle that decays directly to eμ, eτ, or μτ. We use approximately 110   pb−1 of data collected with the Collider Detector at Fermilab from 1992 to 1995. No evidence of lepton flavor violating decays is found. Limits are set on the production and decay of sneutrinos with R-parity violating interactions.
