The alleged rapist of 2 year old zainab in charsadda was the same person who first informed people about her dead body in the fields. He also kept her shoes, presumably as a trophy. These sort of people are not deterred by punishment so it is now crucial that psychological

Profiles be created as aids to predicting their behaviour and catching them sooner. For example the killer will often be in the forefront of the search and will try and insert himself into the investigation. This is not just to avoid blame but also to derive pleasure from the

Impact of his actions and the pain he causes. To feel superior. Also they act out when their impulse cannot be managed. After the killing they cool off but it does not last. It builds and they must revisit and relive the crime and the satisfaction they got. So they will revisit

The scene of the crime and keep trophies. This behaviour must be understood.
