  The CMS experiment recently reported an excess consistent with an invariant
mass edge in opposite-sign same flavor (OSSF) leptons, when produced in
conjunction with at least two jets and missing transverse momentum. We provide
an interpretation of the edge in terms of (anti-)squark pair production
followed by the `golden cascade' decay for one of the squarks: $\tilde q
\rightarrow \tilde\chi_2^0 q \to \tilde l l q \to \tilde\chi_1^0 q l l$ in the
minimal supersymmetric standard model (MSSM). A simplified model involving
binos, winos, an on-shell slepton, and the first two generations of squarks
fits the event rate and the invariant mass edge. We check consistency with a
recent ATLAS search in a similar region, finding that much of the good-fit
parameter space is still allowed at the 95% confidence level (CL). However, a
combination of other LHC searches, notably two-lepton stop pair searches and
jets plus $p_T^{\rm miss}$, rule out all of the remaining parameter space at
the 95% CL.
