Here is a map showing all the places and paths you are taliking about - 5A, the block 6 balcony where the witnesses were, the paths, including the path you ask about.
If you don't know exactly where any of those things are, please ask.
Trust your own measurements using the scale and assess whether your source is veracious or . .... .. ....???

Why have you changed from GEarth to Bing Pegasus? The image on Bing was taken at a time that the alleyways were very overgrown and some cannot be made out; they are hidden by undergrowth.
You usually use google. Could you pease use Google Earth for the same area, from 2007 and show that, cos the bing map image was taken at a time when the paths were seriously overgrown and some are hidden by undergrowth almost completely.
In the immediate area, there are two main alleyways going NNW to SSE and three main alleyways joining the two and going in a SW to NE direction .
Rua Dr Francisco Gentil Martins (Rua FGM) is the main drag where all the toing and froing happened at meal time when checking the kids.
There are three accesses from the more westerly alleyway onto Rua FGM..
The most southerly of these is at the back of Fazackerleys house (number 35 Rua FGM),
The middle one is to the front of his house.
The most northerly one is where Gerry was talking to Raj and Neil and opposite the reception to the tapas area. It opens onto the area where i believe the getaway car was parked in sadies theory.
Any chance that you could post the GEarth 2007 image, please pegasus? It would be clearer for us all.
