The decays of J/{psi}{yields}{omega}KK{pi} and J/{psi}{yields}{phi}KK{pi} are studied using 5.8x10{sup 7} J/{psi} events collected with the Beijing Spectrometer (BESII) at the Beijing Electron-Positron Collider (BEPC). The K{sub S}{sup 0}K{sup {+-}}{pi}{sup {+-}} and K{sup +}K{sup -}{pi}{sup 0} systems, produced in J/{psi}{yields}{omega}KK{pi}, have enhancements in the invariant mass distributions at around 1.44 GeV/c{sup 2}. However, there is no evidence for mass enhancements in the KK{pi} system in J/{psi}{yields}{phi}KK{pi}. The branching fractions of J/{psi}{yields}{omega}K{sub S}{sup 0}K{sup {+-}}{pi}{sup {+-}}, {phi}K{sub S}{sup 0}K{sup {+-}}{pi}{sup {+-}}, {omega}K*K+c.c., and {phi}K*K+c.c. are obtained, and the J/{psi}{yields}{eta}K{sub S}{sup 0}K{sup {+-}}{pi}{sup {+-}} branching fraction is measured for the first time.
