Torsion conjecture for Kauffman bracket skein modules of connected sums

Let $M=M_1\# M_2$, where each $M_i$ is a 3-manifold, possibly with holes, and neither $M_i$ is equal to $S^3$. Let ${\cal S}_{2,\infty}(M)$ denote the Kauffman bracket skein module of $M$. Connected-sum torsion conjecture. The module ${\cal S}_{2,\infty}(M)$ has a torsion element. This conjecture concerns torsion beyond the established torsion arising from a non-separating $S^2$; its status is open.
