On Wh3 of a Bieberbach group

A closed aspherical manifold is a closed manifold whose universal covering space is contractible. There is the following conjecture concerning the algebraic K -theory of such manifolds: Conjecture. Let Γ be the fundamental group of a closed aspherical manifold. Then Wh i (Γ) = 0 for i ≥ 0 where Wh i (Γ) is the i-th higher Whitehead group of Γ.
