A RATHER WEAK MONITORING SYSTEM
One of the main difficulties in this investigation was to reconstruct the chronology of events. To determine the exact time of Madeleine's disappearance, we were dependent on the witness statements of the parents and friends. There is no doubt that the adults (apart from the Paynes, who were using a baby monitor) were taking regular turns during dinner to check that the children were asleep - the restaurant's register confirms it. Nevertheless, after the meal, the children could sometimes be left for more than an hour without supervision. Until May 3rd, the adults made the trip every 30 minutes; on that night, according to what the group said, the intervals between visits did not exceed 15 minutes.
