You're edging towards sounding like ferryman...just because YOU don't know the past case histories and successes doesn't mean there were none
I can only go from what Grime says on his profile... I see two (Devon and Cornwall) cases in which he correctly identified what may well have been residual cadaver scent (or possibly residual blood or other scent within his parameters).
In the two others, there was human material present (one of unspecified nature and another of blood).
(I've left out New Mexico, as Eddie didn't alert even though there was a body as it had been wrapped in plastic and buried under concrete.)
- N. Ireland (ATTRACTA HARRON): Eddie reacted to the physical presence of "human material".
- Wiltshire (AMANDA EDWARDS): reacted to the physical presence of blood. Then identified a deposition site, where presumably a body was found.
- Devon (CHARLOTTE PINKNEY): the dog alerted to her button, and a confession followed to confirm.
- Cornwall (?): the dog alerted to a carpet, and a confession followed to confirm.
We know from the FOI on deployments between 2003 and 2007 that working on his own with Eddie, he found one body. Another four were with Ellis / Frankie, so it's not clear which dog found them, or if they separately both corroborated the finds without the other handler / dog pair knowing in advance. If Eddie found them independently of Frankie, it is still because there were bodies there.
We also know from the FOI that:
"Out of the twenty occasions where the dog teams were deployed together, two deployments were in the South Yorkshire Police Force area and the remainder were out of the force.
All seventeen deployments for Grime/Eddie working alone were to external forces."
And from whichever version of Grime's profile:
Northern Ireland, UKA missing person, last seen returning from church, on foot, in N. Ireland. The
search of suspects 'burnt out vehicle' by forensic scientists did not reveal any
evidence. A search by the E.V.R.D. identified a position in the rear passenger
foot well where the dog alerted to the presence of human material. A sample
was taken and when analysed revealed the victims' DNA. The enquiry then
concentrated its efforts on the suspect and the E.V.R.D. located the body of
the woman in a river bank deposition site. Further searches identified a

location where the E.V.R.D. alerted in the front bedroom of the offenders
empty next door dwelling house. When interviewed the suspect admitted that
the body had lain in the room for 1 hour prior to disposal. Forensic teams
were unable to extract any forensic evidence despite being shown the exact
position.
Wiltshire, UKA female was abducted by her ex-boyfriend. Intelligence suggested that her
ex-boy friend had taken her to his house. A search by the EVRD of the house
resulted in small blood stains being alert indicated and forensically confirmed
as her blood. The suspect, a builder, was in possession of a van. This was
searched and the EVRD dog alerted to a 'wacker plate', spirtit level, and
shovel. A site was identified where the suspect had been working. The EVRD
then located the body deposition site in an area of a garbage base that had
been prepared by the suspect. He had returned with the dead girl, dug a
grave in the centre, placed the body in the hole, replaced the spoil and then
used the shovel, wacker plate and spirit level to return the ground to its
original state.
Devon, UKA female was abducted and her whereabouts were unknown. The suspect
was a bus driver. An initial search by the E.V.R.D. alerted at a location near
to a sighting of the suspect in suspicious circumstances. A forensic search at
the alert location revealed a small button off of the girls clothing in long grass.
The offender confessed to the murder and confirmed her body had been
initially temporarily placed at the dog's alert location.
Cornwall, UKA woman was reported missing by her partner. A search of the suspects
house by the EVRD was conducted who indicated on the living room carpet.
No forensic evidence was recovered. Subsequently a diary written by the
suspect was alert indicated by the dog. The diary had written extracts that the
offender had laid the victim on the carpet whilst dead, the diary had in fact
been written by the suspect having handled the body. This was confirmed by
the offender in interview.
New Mexico, U.S.A.
A witness reported having seen two men walk off into brush land carrying a
spade and a corpse. The area was searched with the EVRD with no
indications being forthcoming. Other assets were utilised and the body was
found: buried at a depth of 8 feet, under the water table, 3 feet of cement and
5 feet of earth replaced on top the corpse that was wrapped in cling film.
There being no scent available to the dog to receive there was no forthcoming
