Abstract: 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: $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{q}\ensuremath{\rightarrow}q\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\chi}}$, $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\chi}}\ensuremath{\rightarrow}\ensuremath{\nu}\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\ell}}$, $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\ell}}\ensuremath{\rightarrow}\ensuremath{\ell}{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\chi}}}_{1}^{0}$. Such a supersymmetric origin also leads to events with large missing transverse energy and either 0, 1, 2 same-sign, or 3 isolated charged leptons.
