It is understood that the hammer was not the one used to kill Mrs James.

The police suspect that Thijssen had two hammers with him, the other of which may have come from a school storage room.

Police divers managed to recover Thijssen’s bloated and battered body from the rocks below the cliffs at Diamond Bay.
