SYP response:
Thank you for your request for information in relation to:
1. Which cases has Eddie the Springer Spaniel sniffer dog been used in within the South Yorkshire Force area over the last five years?
(snipped)
As two teams working together: handler
Ellis and dog Frankie, with handler Grime and dog Eddie have been deployed on twenty occasions, with the recovery of four bodies.
Working alone, Grime/Eddie have been deployed on seventeen occasions with the recovery of one body and Ellis/Frankie have been deployed on five occasions with the recovery of three bodies, this includes the recovery of two women in one grave.
End quote
Eddie and Grime have been deployed on a total of 37 occasions over 5 years. Only on 17 of those occasions were Eddie and Grime working alone - finding one body.
This would appear to be a far cry from the 200 cases claimed by some.
IMO
