We report on the observation of (B) over bar -->D*pi (-) pi (-) pi (0) deca
ys. The branching ratios for D*(+) and D*(0) are (1.72 +/-0.14 +/-0.24)% an
d (1.80 +/-0.24 +/-0.27)%. respectively. Each final state has a D*omega pi
(-) component, with branching ratios (0.29 +/-0.03 +/-0.04)% and (0.45 +/-0
.10 +/-0.07)% for the D*(+) and D*(0) modes, respectively. We also observe
(B) over bar -->D omega pi (-) decays. The branching ratios for D+ and D-0
are (0.28 +/-0.05 +/-0.04)% and (0.41 +/-0.07 +/-0.06)%, respectively. A sp
in parity analysis of the omega tau (-) system in the D omega tau (-) final
state shows a preference for a wide l- resonance. A fit to the omega pi (-
) mass spectrum finds a central mass of (1349 +/- 25(-5)(+10)) MeV and widt
h of (547 +/- 86(-45)(+46)) MeV. We identify this object as the rho (1450)
or the rho'.
