  It was a possibility.  That's why I told them specifically to dress in old clothes that I can take hold of after the murder and destroy, to make sure that they wear no watches with serial numbers on that could fall off their arms during a possible struggle, or any pocket material, like cigarette boxes with numbers on, or matchboxes with numbers on, but to make 100% sure that they had nothing on them, and whatever they were dressed in I took hold of until such time as it was reported to me that nothing at all, no traces, were found at the scene.
