Having gone through the various statements of the staff associated with Ocean Club, Praia da Luz, the following times would appear to be quite accurate.
G.N.R. Officers Roque and Costa were the first police to arrive at the club. Both stated their time of arrival as being 11pm. When they arrived, they saw the girl's father, a friend whom he cannot describe, an OC employee and a translator who was also an OC employee, named Silvia Batista.
Silvia Batista for her part stated that she was made aware of the disappearance at 10.30pm and was told of it in a telephone call from Club admin George Crossland.
Crossland stated that he had been contacted by the Club Manager John Hill at 10.15pm and immediately set out for the premises arriving at the Club some 10 minutes later.
Ocean club manager John Hill stated that he was alerted to the disappearance by Head of Child Care, Lyndsay Johnson. He puts this contact at 10.28pm and the G.N.R. arrival at 10.45pm.
Lindsay Johnson for her part stated that Amy Tierney told her of the drama at 10.20pm and that 5 minutes later the "missing child" procedure was activated.
Finally, crèche worker Amy Tierney recalls that she was on duty and was immediately alerted to the incident. She added that Madeleine's father went to reception to call the police as soon as her disappearance was noticed and that 20 minutes had passed. The G.N.R. took 30 to 35 minutes to arrive.
All in all we can deduce from these independent witnesses that Kate must have alerted the group some time between 10pm and 10.10pm.
The tapas group for their part put the time of the first alarm being raised at 10pm.
