JLab has recently found indications of the possible existence of a $\SigmaNN$ resonance at $(3.14 \pm 0.84) - i (2.28 \pm 1.2)$ MeV. In the past, usingmodels that exploit symmetries between the two-baryon sector with and withoutstrangeness, hyperon-nucleon interactions have been derived that reproduce theexperimental data of the strangeness $-1$ sector. We make use of theseinteractions to review existing Faddeev studies of the $\Lambda NN$-$\Sigma NN$system that show theoretical evidences about a $(I,J^P)=(1,1/2^+)$ $\Sigma NN$quasibound state near threshold. The calculated position of the pole is at2.92$\,-i\,$2.17 MeV, in reasonable agreement with the experimental findings.
