The CDF and D0 collaborations have both reported unusual events in the dilepton+jets sample with very high lepton and missing transverse energies. It is possible, but very unlikely, that these events originate from top quark pair production; however, they have characteristics that are better accounted for by decays of supersymmetric quarks with mass in the region of 300 GeV: $\widetilde q \to q \widetilde \chi$, $\widetilde\chi \to \nu\widetilde\ell$, $\widetilde\ell\rightarrow \ell \widetilde \chi_1^0$. Such a supersymmetric origin also leads to events with large transverse missing energy and either 0, 1, 2 same-sign, or 3 isolated leptons.
