We consider the Cauchy problem for the massive Dirac equation in the
non-extreme Kerr-Newman geometry outside the event horizon. We derive an
integral representation for the Dirac propagator involving the solutions of
the ODEs which arise in Chandrasekhar's separation of variables. It is
proved that for initial data in Linfinityloc near the
event horizon with L2 decay at infinity,
the probability of the Dirac particle to be in any compact
region of space tends to zero as t goes to infinity. This means that the
Dirac particle must either disappear in the black hole or escape to infinity.
