  We derive and present expressions for the kinematic endpoints that arise in
the invariant mass distributions of visible decay products of cascade decays
featuring a two body decay followed by a three body decay. This is an extension
of a current technique that addresses chains of successive two body decays. We
then apply these to a supergravity model with Non-Universal Higgs Masses
(NUHM), having simulated a data set using the ATLFAST detector simulation. We
find that, should such a model be chosen by nature, the endpoints will be
visible in ATLAS data, and we discuss the problems associated with mass
reconstruction in models with a similar phenomenology.
