A statement released by the Find Madeleine fund said that “all information privately gathered during the search for Madeleine has been fully acted upon where necessary” and had been passed to Scotland Yard.
It continued: “Throughout the investigation, the Find Madeleine fund’s sole priority has been, and remains, to find Madeleine and bring her home as swiftly as possible.”
crucially the statement did not say when they handed the e-fits over. Indeed the ST article says they were handed over when SY requested them.
The fact they handed them over is not the point. It's why they held them back and why they handed them over when they were asked.
Given the serious implications of the ST's article if it was untrue then a more firm and strongly worded denial would be issued and no doubt swift legal action would have been instigated and publicised to combat the inference of the article.
Bearing in mind SY know all the facts it's hard to deny something that's true with the yard watching.
Which is why they haven't of course.
