We report the results of a search for the anomalous production
of a massive particle decaying to four electrons via two Z0 bosons in 1.1
fb-1 of p anti-p collisions at s**(1/2) = 1.96 TeV collected by the CDF
II detector at Fermilab. We employ optimized electron identification
criteria to maximize acceptance and efficiency. We estimate the
backgrounds in the invariant mass range 500 - 1000 GeV/c2 to be 0.028
+/- 0.009 (stat) +/- 0.011 (syst) events. We observe zero events in
this search region. Assuming a Randall-Sundrum graviton production
model, we set 95% CL limits on sigma x BF(G --> Z0 Z0) < 4-6 pb,
depending on the graviton mass.
