  We establish the means by which Mr. Boddy came to transition from a stable
trajectory within the global phase space of Philadelphia, Pennsylvania to a
stable point on the cement floor of an aviary near the west bank of the
Schuylkill River. There exist no documented murder motives, and so the
dynamical interaction leading to the crime must be reconstructed from
circumstantial data. Our investigation proceeds in two stages. First we take an
audio stream recorded within the aviary near the time of death to identify the
local embedding dimension, thereby enumerating the suspects. Second, we
characterize Mr. Boddy's pre- and post-mortem behavior in the phase space in
terms of an attractor that undergoes an abrupt change in stability. A
supercritical Andronov-Hopf bifurcation can explain this transition. Then we
uniquely identify the murderer. Finally, we note long-term plans to construct
an underlying dynamical model capable of predicting the stability of equilibria
in different parameter regimes, in the event that Mr. Boddy is ever murdered
again.
