  Experimental results of a search for the Xi_(3/2)(1860) cascade pentaquark
state in data collected with the CDF 2 Detector in Run II at the Tevatron are
presented. No evidence for these states in the neutral Xi-pi+ and doubly
charged Xi-pi- modes has been found. Preliminary upper limits on yields at 1862
MeV/c**2 relative to the well established resonance Xi*0(1530) are presented.
