Here's a tale that I was told whilst in training. Although it sounds like a tall story judging by the miss match of random knives, forks and various other kitchen utensils lurking in the cutlery draw in our nick I can see it could be true.
Some years ago there was a small rural station that the powers that be had decided needed knocking down and a new station needed to be built in its place. So the old station needed to be cleared out.
As one of the officers was clearing out the property store he came across some photos of a murder that had happened many years previously. There were of course pictures of the victim, the murder scene and the murder weapon. The murder weapon was a distinctive long wooden handled bread knife, with a serrated edge, and where there was once two prongs on the end of the knife there was now only one.
Hmmm, the officer thought to himself this knife looks familiar. He then realised this murder weapon had someway found its way into the cutlery draw and they had been using it for all these years since!!!
