When a picture paints a thousand words (OK, maybe 100 in this case).
Thank you for taking the time to post the diagram, but for the record I was aware of this diagram.
My original points were:
There are two potential anomalies in the statements with respect to the sighting: (1) GMcC reports the JT as being 50m from the individual, which would place JT at the entrance, and (2) JT reports:
4078 “And was that, is there another pavement there, on the junction?”
Reply “No, they were on, there’s a junction, this is sort of the road and they were walking along the side of the pavement, then I would then walk along”.
4078 “So they were on the same side that you were about to walk along?”
Reply “Yeah”.50m would place JT at around the entrance to Tapas bar i.e. the door where the tracker dog trail was lost.
The second point, which I did not make explicit enough, was that JT uses the word "along" as opposed to the word "across". This could be a Fredudian slip, but only in the sense that her subconscious mind leaked what she had seen, not a deliberate misleading statement or mistake.
If you take these two points, with my view that it is entirely possible JT was mistaken as to the timing of her sighting: i.e. the sighting occurred when she went to 'relieve' ROB, then the following scenario is a possibility:
1. The tracker dog trail ends around the door of the entrance, which gives access to the Tapas Bar/pool area.
2. A third party carried off MBM whilst walking up R. Francisco Gentil Martins.
3. As the third party approached the top of the road, JT exited the Tapas Bar to 'relieve' ROB.
4. JT saw the third party, at a distance of about 50m, who then crossed to the road.
I'm sure many will not agree this happened, and I cannot prove this happened, but it is not a completely unrealistic scenario.
