No, I don't have a reference at hand to give to you about António Castela. I have a memory though.
And the question is not if the McCann are innocent or guilty but why don't they open their game and tell all they know about what happened without subterfuges.
António Castela on his first interview to the journos said that he transported a child, that he later identified as M.McCann, accompanied by a woman that he believed was Kate McCann and 3 men, one of which looked like Murat. According to his deposition to the PJ, as related to the journalist from Correio da Manhã, the ride was between Vila Real de Santo António and a Hotel in Monte Gordo (about one kilometer away and more than 70 km from Praia da Luz). This, according to the interview, happened on the 3rd of May, 2007 at 20:10h.
If you were the police how much credit would you give to this account?
In fact, even the spokesperson to the McCann discarded that witness at the time.
Oh, you are way out with that measurement Luz.
Almost twice that and maybe a little more than that, following the roads.
Lets err on your side and say 130km = over 80 miles
Some of it is fast but much of it is not so fast.
Check it on GEarth. 1) Use the upright blue rule at the top of the page.
2) click on it and when the banner comes down,
3) click on path.
4) Now change the unit of measurement: yards. metres, miles, kilometres etc to the unit you want, presumably kilometres
You are now ready to start measuring the path/roadi) Move the pointer to Monte Gordo , click
ii) Move the pointer to the next corner or curve. Click on it
iii) Move the pointer along a bit more along the road and click
iv) Eventually you will come to the junction of the N120 above PdL. click
v) then down to OC, click
vi) The distance of the path comes up in the little box automatically. Kilometres can be changed to miles, and miles to kilometers
I have only measured roughly and have cut corners a bit. It is quite a drive
