Thanks Anne. I think the cadaver dogs should check inside the bins? If they find one positive sign inside a bin it's evidence.
I'm now thinking the child was possibly wrapped up inside Smithman's black jacket when hidden in the dark after passing the Smith family down towards church/rocky shore area.
Portugal had no cadaver dogs then, but tracker dogs and rescue dogs. Those usually are repelled by cadaver scent, so they would be of no use for bins. Handlers by rule don't bring their sniffer dogs in too smelly parts, because the dogs exhaust themselves trying to find the right scent. People mock this, saying the dog is attracted by garbage. This is shameful, the dog tries very hard to discriminate. I'm talking of professionally trained dogs of course.
I'm pretty sure no dog smelt the bins. The files say that the bins were checked on the 7th, much too late. Some benevolent searchers searched some bins on the 4th. Too late. I was told the PJ went on the landfill. Too late. Hundred of tons of compressed garbage had been deposited since the 3rd of May.
If Smithman, scared that an autopsy would determine the cause and manner of death, intended to get rid of a body, this was the unique secure way.
