first_imgBillie the cocker spanielCredit:Derbyshire Constabulary Police in Derbyshire have employed the services of new crime fighter with a knack for sniffing out rapists.While his canine colleagues are off hunting for drugs or explosives, Billie the cocker spaniel’s nose is trained to find DNA evidence used in sex cases.Billie does it by tracking down traces of human semen. Dogs are believed to have a sense of smell that is about 10,000 times more acute than that of humans meaning Billie can detect as little as a millilitre of sperm more than a year after it was deposited indoors.Well-trained dogs can pick up some smells when they are diluted down to a few trillionths of a litre. This is the equivalent of identifying a pinch of salt in an Olympic-sized swimming pool.Since March this year Billie has carried out 13 live searches, according to a document drawn up by Derbyshire Constabulary, The Times reported.

In one case involving a suspected peeping Tom, the investigation team had found nothing at the crime scene but removed some items, including boards recovered from a loft, to the garden for searching.”Despite CSI not being able to see any stains via the crime light, the dog indicated several areas on one of the boards. That board has now been seized for laboratory analysis,” the police briefing reads.Superintendent Dick Hargreaves, of Derbyshire Constabulary, said Billie was “a real asset”.”He’s already been used in numerous investigations and has found further evidence that has resulted in crime scene investigators identifying DNA profiles,” he said.”We are always looking for innovative ways to improve our service and we’re hoping that Billie’s skills will lead to more convictions.”last_img
