Data from MARK 3 on the decay J/{psi} {yields} {pi}{sup {minus}}{pi}{sup +}{pi}{sup 0} are described in terms of amplitudes representing the sequential two-body decay processes J/{psi} {yields} {rho}{pi}, {rho}{yields}{pi}{pi}. It is found that a complete description requires contributions from excited J{sup PC} = 1{sup --} states in addition to the dominant contribution form the {rho}(770). The characteristics of these additional states are discussed. 11 refs., 6 figs.
