    We report on the observation of ${B}\to D^{*}\pi^+\pi^-\pi^-
    \pi^o$ decays. The branching ratios for $D^{*+}$ and $D^{*o}$ are (1.72$\pm$0.14$\pm$0.24)% and (1.80$\pm$0.24$\pm$0.25)%, respectively. Each final state has a $D^{*}\omega\pi^-$ component, with branching ratios (0.29$\pm$0.03$\pm$0.04)% and (0.45$\pm$0.10$\pm$0.07)% for the $D^{*+}$ and $D^{*o}$ modes, respectively. We also observe ${B}\to D\omega\pi^-$ decays. The branching ratios for $D^{+}$ and $D^{o}$ are (0.28$\pm$0.05$\pm$0.03)% and (0.41$\pm$0.07$\pm$0.04)%, respectively. The $\omega\pi^-$ appears to come from the decay of a wide $1^-$ resonance. A fit to a Breit-Wigner shape gives a mass of 1418$\pm$26$\pm$19 MeV and width of 388$\pm$44$\pm$32 MeV. We identify this object as the $\rho$(1450) or $\rho'$.
