Residually free 3–manifolds

We classify those compact $3$ –manifolds with incompressible toral boundary whose fundamental groups are residually free. For example, if such a manifold $M$ is prime and orientable and the fundamental group of $M$ is nontrivial then $M ≅ Σ \times S^{1}$ , where $Σ$ is a surface.
