By using a quadrupole focused neutrino beam, 61 events with two muons in the final state have been observed at Fermilab. These include seven $mu$$sup - $$mu$$sup -$ events. A comparison of the event rate in two targets of different hadron absorption length indicates that attributing the events to $pi$ or K leptonic decay is ruled out by 4.0 standard deviations. No trimuon events were observed; this circumstance, combined with lepton conservation, indicates an unobserved neutral lepton is present in most of the events. (AIP)
