Leptoquarks with mass in the region of 550-650 GeV are a possible candidate for the recent excess seen by CMS in the eejj and evjj channels. We discuss models where leptoquarks decay primarily to dark matter and jets, thereby giving a branching to charged lepton and jet final states that can match data. The confluence of proton decay constraints, dark matter indirect and direct detection data, and Higgs invisible decay bounds results in a handful of predictive models that will be conclusively verified or excluded in upcoming direct detection experiments. Along the way, we present robust limits on such leptoquark models stemming from the muon magnetic moment using current and projected experiment sensitivities, as well as from K and B meson mixing, and leptonic and semileptonic meson decays.
