  Recent theoretical studies have indicated that the topological features of
away-side jet fragments can be significantly altered by medium-induced
modifications. The leading candidates resulting from such modifications are
Mach Cones and deflected jets. We show that three particle correlations are
able to distinguish between these different modification scenarios. Initial
results from an application of the method to Au+Au collisions at RHIC
($\sqrt{s_{NN}}=200$ GeV) are presented.
