It is encouaging to hear that a fresh attempt is being made to catch the killer of Eila Karjalainen.

The Finnish student on a hitchhiking holiday was found dead in undergrowth on the Blenheim estate at Woodstock 21 years ago, and her murder was never solved.

Now Terry Sykes, one of the police officers in the hunt, is making a fresh appeal for help in his new role as a coordinator with Crimestoppers.

He is hoping that anyone with information will call the confidential crimeline, which did not exist when the murder took place.

There have been numerous cases recently where DNA and other technological advances have identified criminals many years after they committed offences.

Crimestoppers may not be as scientific, but it is a simple and straightforward way of giving information to the police without giving your name.

Criminals everywhere, who thought they had got away with their misdeeds, must be shaking in their boots wondering if the law will one day catch up with them.

The brute who killed Eile had better keep looking over his or her shoulder.
