You need to read what Grime says in his statement..
The dogs only alerted to property associated with the McCann family. The dog
alert indications MUST be corroborated if to establish their findings as
evidence.
Therefore in this particular case, as no human remains were located, the only
alert indications that may become corroborated are those that the CSI dog
indicated by forensic laboratory analysis.
Yes but you need to watch what he says about Eddie’s alert in the Police videos.
He is always consistent with regards to the need for corroborative evidences. That’s why they use the two dogs together and try to locate blood for DNA analysis from the white blood cells. If Eddie’s alerts are not to cadaverine then you must concede it is likely that he’s alerting to blood. There’s too many alerts and only in relation to one specific family to dismiss the need for further DNA analysis of the evidence collected, IMO. As the sample from swab 3a contains DNA from more than one person this could be vital to establishing a link to the German sex offender, perhaps.
