What routes are left to investigate re: the McCanns?

The highest temperature ever recorded on earth was 56.7 degrees, where did you go on your  holiday - Venus?

OK I think I was wrong. I Have just checked and it was just over 50 degrees. Still a little warm.

I think the fact that the child had been missing for 50 years was a clue Rob.

"A body that was discovered in a landfill in Pennsylvania nearly 50 years ago has been identified as a 13-year-old Pittsburgh girl who was last seen in 1967.

DNA tests show that the body, which had been exhumed from an unmarked grave from a cemetery potter's field last fall, is that of Teala Patricia Thompson, Pennsylvania State Police said Thursday."

So most of the time it was in a grave rather than a landfill.  At the landfill it might have only been on the surface and discovered quickly.

Up to 55⁰C ?
One can hold an object that is 55⁰C without burning skin.

At work hand wash water was targeted to be 42 degrees.  If it ever got over 45 degrees it became uncomfortable 49 degrees is too hot you will pull yours hands out of the flow.  Whether 55 degree would denature DNA I'm not sure but I think you could cook meat at 55 degrees.

Imagine a body left in that heat!

https://en.wikipedia.org/wiki/Low-temperature_cooking
"Low-temperature cooking is a cooking technique using temperatures of 45 to 85 °C (113 to 185 °F) for a prolonged time to cook food. Low-temperature cooking methods include sous vide cooking, slow cooking using a slow cooker, cooking in a normal oven which has a minimal setting of 70 °C (158 °F), and using a combi steamer providing exact temperature control."

That may be so but it does not negate my comment.
The point goes back to davel's post where he stated, and I paraphrase but the sense does not change, "an enormous amount of heat is generated by landfill enough to destroy etc......"
My points were:
1) Landfill sites are run at 35⁰C to 55⁰C high temperatures ie 90⁰ C and above damage the polymer membranes that are required [Refer EPA and DEFRA].
2) 55⁰C is not enough to burn skin hence protective insulation for pipes carrying a hot medium is fitted at 60⁰C. [Refer ASTM C1055 & BS5970].
3) Collagen requires a temperature of 200⁰C to break down.
4) Bone is destroyed at a temp of 1500⁰C

Beyond those points speculate away but deal me out.

All of your slow cooler cooking involve water. There would be very little water in the landfill site. That is why landfill sites will mummify matter.  The water leaches out of a landfill site into the local groundwater.   If you watch this link below  will see what happens to things in a landfill.  Near the end (around 1hr 08mins) they excavate a 30 year old landfill and it is amazing what they find.

They didn’t show many intact tubs of guacamole, it all looked like metal and plastic to me :-/

Sous Vide involves an airtight bag with no water inside... Please correct your post according ly

There was a case recently of a young man whose body was presumed to have been carried in a garbage truck to the tip and buried.  It happened within the last couple of years or so.  I believe the tip was extensively searched but no body was discovered, though the police are adamant that’s where he ended up.  I believe his family have accepted this the most likely explanation for his disappearance.  Given that the police couldn’t find a grown man in landfill a year or two after his disappearance, what is the likelihood of being able to find a small girl’s body buried 11 years hence?  And what could the body tell the police to help them secure a conviction against the McCanns anyway?

Part of police remit was to discover what happened to Madeleine.
Discovery of her body would go some way towards that.

I think not


Sous-vide cooking
Sous-vide (/suːˈviːd/; French for "under vacuum")[1] is a method of cooking in which food is placed in a plastic pouch or a glass jar and cooked in a water bath or steam environment for longer than normal cooking times (usually 1 to 7 hours, up to 48 or more in some cases) at an accurately regulated temperature. The temperature is much lower than normally used for cooking, typically around 55 to 60 °C (131 to 140 °F) for meat, higher for vegetables. The intent is to cook the item evenly, ensuring that the inside is properly cooked without overcooking the outside, and to retain moisture.

Yes I am aware of that, however someone else on this thread suggested that the PJ would be looking for her body in the landfill in order to find evidence against the McCanns, which incidentally is what this thread is about.

Crikey!  Who was that?
