Eddie alerted many months after in Parker (garage), Prout (living room) and Harron (bedroom) cases to name a few so it's not unusual to the police for this to happen again. Eddie was not brought into missing person cases until later.
"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."

The really compelling evidence in the three cases you mention was the discovery of human remains.
In two of the cases ... Prout and Parker ... there had been sufficient evidence to enable murder trials to take place and the perpetrators of the crimes to be found guilty on the strength of it.
Both were serving their sentence before their wives remains were found.
In the case of Mrs Harron's horrific murder there was no guess work about the areas appropriate for the dogs' inspection. There was plenty of evidence exactly where to point them ... and in the places alerted to, the alerts were backed up with strong forensic evidence.
In my opinion Mrs Harron's death must have been a blood bath making the key fob scenario in Luz risible were it not so tragic.
Categorically there is absolutely nothing which is of the remotest similarity between these three cases you have quoted and Madeleine McCann's disappearance in Luz.
The forensic testing as a result of places of interest shown by the dogs in Luz has shown there is no evidence which backs up the slightest connection to Madeleine McCann. Nor is there even circumstantial evidence pointing to her death.
Stuff and nonsense in my opinion to keep labouring a point which just does not exist and never has.
SnipOn February 20, 2004, police employed the use of the Victim Recovery Unit dogs from England, which were highly trained to detect and alert handlers to the presence of human remains. A video without sound was shown in the court showing a Springer Spaniel dog examining two cars and a small van before being taken to the Lantra that had been driven by Hamilton and subsequently burned out, allegedly maliciously.
The video clearly showed the spaniel examining the other vehicles without reacting, and as soon as it entered the Lantra it began barking and refused to get out. Its search of the vehicle focused on the front passenger and rear seats.
Further forensic examination was carried out in the rear and passenger compartments of the vehicle and blood was detected from material taken from the car for examination. A car mat from the rear of the car was also shown to contain blood, and because of that, the investigation focused on Hamilton, Mr Mooney said, which included a comprehensive search of the property at Concess Road and in particular the sites of fires in the garden.
Recovered from these were rosary beads, blue plasters, a religious text, a business card, red material and an AIB bank receipt, all of which Mr Mooney described and linked to Mrs Harron; the rosary beads were identical to a set owned by Mr Harron; the bank receipt came from a withdrawal of cash made when Mr and Mrs Harron were at a wedding anniversary function in the south of Ireland on September 5, 2003; the business card was from an architect involved in the design of the new library in Strabane who was friends with Mrs Harron; the plaster matched those exactly which were missing from a box of plasters Mrs Harron bought in Lidl and which bore the same batch number, and the religious text came from a book of devotions available during a special service at the Church of the Immaculate Conception at Barrack Street or from the local religious shop in Strabane.
All of this Mr Mooney said, when taken together, provided compelling evidence connecting Hamilton to the late Mrs Harron.

Mr Mooney said the chances of the blood not being Mrs Harron’s were a billion to one and for that reason any notion that it was not her blood in Hamilton’s car could be discounted.
“You cannot elimiate Mrs Harron as being the person who was the source of the blood on the mat,” he told the silent courtroom, adding: “The chance of another person being the source of the blood other than Attracta Harron is so minute it can be safely discounted”.
