Following the discovery of Ms Walsh's body, police in South Yorkshire were asked to bring Keela and Eddie,
Why would you bring in a cadaver dog after finding a body?
Finding bodies is what cadaver dogs do.
Thereafter, you bring in the so-called crime scene investigation dog.
(A dog like Keela) ....
Eddie was brought in after the body was found to find any further evidence of death in other places such as her home to find out where she was murdered. Suspects clothes tested etc.
Six-year-old English springer spaniel Eddie from South Yorkshire Police and his female companion Keela have formed part of a specialist dog team hunting for clues after the 35-year-old's badly decomposed body was found floating in Waterford Quays on October 15.
Martin Grime, who handles both Eddie and Keela, said today: "Obviously the body had been found already, so we went into investigative mode and the dogs were brought to Waterford and Dublin.
"Eddie would be tasked to tell us where the body had been before it was found and would indicate any clothing that would have come into contact with the body.
"Keela was there to find any blood traces.
"We cannot comment on whether the dogs found anything as the investigation is still ongoing."
