Decay properties of multi-strangeness Ξ and Ω baryon resonances are investigated within the constituent quark model by including relativistic corrections. The strong decay widths of various Ξ and Ω resonances are computed and tested for internal quark configurations to pin down their spin-parity (JP) quantum numbers and internal structures. We found that the Roper-like resonances in the multi-strangeness sector have large decay widths bearing resemblances to their siblings in light and heavy baryon sectors. In addition, we obtained the decay ratio for the Ω(2012) as Γ(Ω→ ΞK π) / Γ(Ω→ ΞK)=4.5%, which is consistent with the experimental data when JP=3/2- is assigned. This observation holds the possibility that the Ω(2012) could naturally be explained as a three-quark state in the quark model. The decays of other low-lying Ξ and Ω resonances are systematically analyzed, which would be useful to unveil the structure of these resonances in future experiments.
