What I have noted about Lyndsay's statement is that she appears to be on hand at the time. It is not clear how Amy informs her from Lyndsay's statement.
"She indicates that on May 3rd 2007, at around 10.20pm, she was informed by her colleague Amy T. that Madeleine McCann had disappeared. At that, she immediately launched the "missing child" procedure. This procedure consists of dividing the site into several areas, which are allocated to various of the company's employees to start searching for the missing child. To that effect, the informant explains that, around 10.25pm, the date indicated, the said procedure was begun, dividing the whole site into three distinct areas, namely the north zone, the central zone (including the area of the company) and all the roads surrounding the company and which go as far as the beach. Five of the company's employees were mobilised to coordinate the searches, helped by various people ( other employees, tourists and residents)."
OK there could be a 5 minute delay (was that related to her travel time to the site) Where does the Missing Person procedure get handled from? Did they meet at the main reception or at the Tapas area?
Maybe Amy tells us how she informed Lyndsay.
The only indication from Amy's statement is this "After having searched the apartment and verified that the girl was not there, the outside searches were begun."
Comparing that with what Lyndsay says "at around 10.20pm, she was informed by her colleague Amy T. that Madeleine McCann had disappeared. At that, she immediately launched the "missing child" procedure. "At that, she immediately launched the "missing child" procedure.
OK between launching it and beginning the searches there was a mere 10 minute or so getting ready state:
"To that effect, the informant explains that, around 10.25pm, the date indicated, the said procedure was begun"
They need staff to operate the procedure so that would take a bit of time to gather the troops.
