The HyperCP collaboration at Fermilab is searching for CP violation in charged
hyperon decays by comparing the angular  decay distributions of protons and
anti-protons from Xi-minus -> Lambda + pi-minus and anti-Xi-minus ->
anti-Lambda + pi-plus decays.  Using a hyperon data sample orders of
magnitude larger than any other experiment has collected, we report a
preliminary result with a sensitivity of O(10E-4) from an analysis of the
entire HyperCP data set of over one billion events.
