I have found Jane's statement although you won't or can't. Why she would assume that Europeans would be able to convert feet and inches to metres I don't know. The onus was on Jane to be clear what she meant in my opinion.

The egg head drawing was not made by the PJ, it was made by Simon Russell.

Why anyone would suggest that the PJ were showing it to people I can't imagine.
Edited removed goading.
The drawing was produced by Simon Russell based on a drawing shown to him by the Policia Judiciaria.
SnipOfficers have not released any photofit or artist's impression of the suspected abductor.
But they have, apparently, shown a sketch like this to residents in Praia da Luz.
One of them was Simon Russell, 40, runs a video store and Internet cafe in the former fishing village.
"I smiled when they showed it to me. What else could you do?" he said.
He said the sketch was so simple it was easy for him to recreate, and it is Mr Russell's drawing that is used here.
He described it as looking like "an egg with a side parting".
The fact that such a virtually useless image is being used underlines claims that the Portuguese police are getting increasingly desperate.
"They have got absolutely nothing and are following up lines of inquiry which are barely credible," said a British police source familiar with the inquiry.
