"The Government’s National Policing Improvement Agency (NPIA) said specialist victim recovery dogs are not trained to approved standards, with no way of gauging their competence."
How about starting with false alerts? How many false alerts had Eddie according to Martin Grimes?
"The dogs' CV is impressive. Besides collaborating in hundreds of investigations, they passed the practical tests brilliantly at the FBI's "Body Farm," the only place in the world where human cadavers are used to simulate homicide scenarios and concealment of bodies.
Amongst the most media-covered cases, which they contributed to resolving, is that of the disappearance in Northern Ireland of Attracta Harron, who was last seen when she was returning home on foot, after having been to church. All searches carried out by the police were unsuccessful. The main suspect's car having been totally burnt out in a mysterious fire, couldn't be examined. They called in Eddie, who examined the charred remains of the vehicle and immediately picked out the characteristic odour. Human tissue was found amongst the debris, the DNA of which corresponded to the missing woman. Later, the dog indicated the place - close to a river - where the victim's body had been abandoned. At the home of the suspect, where the police were searching for incriminating evidence, Eddie identified cadaver odour in one of the bedrooms. The man confessed to having killed the woman then moving her body to the banks of the river.
The case of Amanda Edwards, reported missing, is also very impressive. The police, who conducted a search of her ex-partner's home, found small bloodstains there, but no trace of a body. The dog, who was brought in for the examination of the man''s vehicle, alerted to cadaver odour on the tools stored in the boot (a shovel, a level and a compactor). The police went to the building site where the suspect had worked a few days before and discovered the body, buried in a garage. The murderer had made efficient use of his tools to carry out his task.
It's also thanks to the help of the dogs that the case of Charlotte Pinkley, a missing British woman, who had been imprisoned by her ex-partner, was resolved. The police requested the help of the specialist dog team to try to find the young woman's body. Eddie picked out a place where the abductor had provisionally left his victim. In the surrounding area, the investigators found the button from a dress that had belonged to Charlotte. That clue exposed the murderer, who ended up showing the police the place where he had hidden the body."
