A new particle Σ* with JP = 1/2- was predicted by unquenched quark models with its mass around the well established Σ*(1385) with JP = 3/2+. Here we re-examine some old data of the K-p→Λπ+π- reaction. We re-fit the data for kaon beam momenta in the range of 1.0-1.8 GeV and the energies around Λ(1520) peak. Both studies show evidence for the existence of Σ* with JP = 1/2- around 1380 MeV. And then we also study the recent data on Σ*(1385) production in the γn→K+πΛ reaction by the LEPS collaboration and the reaction K-p→π0Λ by the Crystal Ball Collaboration. Our results not only indicate the possible existence of Σ(1380)1/2-, but also firmly confirm the existence of Σ(1660)1/2+.
