We have analyzed the Collider Detector at Fermilab {ital ee}{gamma}{gamma}+ missing energy event. Its kinematics and expected rate are consistent with selectron pair production. We consider two classes of general low-energy supersymmetric theories where the lightest neutralino or the gravitino is the lightest supersymmetric particle. The supersymmetric Lagrangian is tightly constrained by the production and decay of the selectron and other data. We discuss other processes at the Fermilab Tevatron and at LEP that could confirm or exclude a supersymmetric explanation of the event. {copyright} {ital 1996 The American Physical Society.}
