We present a preliminary result from a search for walking technicolor particles using leptonically decayed {ital W} plus two jets with at least one b-tag using 109{plus_minus}7pb{sup {minus}1} of data taken by the Collider Detector at Fermilab (CDF). We search for technipion mass peaks in the invariant mass distribution of the two jet system and technirho mass peaks in the invariant mass distribution of W+2jet system. We do not see any significant excess in our search sample, and set 95{percent} confidence level upper limits on the production cross section and exclude a region of the {pi}{sub T} mass v.s. {rho}{sub T} mass plane. {copyright} {ital 1998 American Institute of Physics.}
