I must just point out how meticulous AE was. During one of her " searches " whilst at WHF,,she came upon a cobweb ( I kid you not ) with a bloodstain on it,,so it was immediately reported to COLP.!
The said cobweb was above the hinges inside a cupboard which she was clearing.
DCI O'Connor thought it would be helpful,so proceeded to record the finding. This was in 1991,so he said it would be analysed to see if it had any bearing on the 1985 murders.
However,,DI Harper was brought in to attend to the findings of the cobweb and decided that a visit to WHF would be in order to examine the cobweb.! The sample would then be retained for analysis.
