  We present additional studies of the kinematics of the anomalous events
observed by the CDF experiment. These events contain a high-$p_T$ lepton, large
transverse missing energy ($\MET$), and 2 or 3 high-$E_T$ jets, one of which
contains both a displaced secondary vertex and a soft lepton. Previous articles
detailed the selection and the kinematic properties of these events. In the
present paper, we use several phenomenological approaches to model these data
and to estimate their production cross section.
