Her parents reported to the police that they had taken Madeleine to their holiday apartment at 18:00 Western European Summer Time, to prepare Madeleine and her two-year-old twin siblings for bed.[14] Then they left at 20:30, leaving the apartment unlocked, to dine with friends approximately 130 yards (120 metres) away at a tapas bar within the Mark Warner Ocean Summer Club.[1][15] The McCanns said that they were taking turns checking on their children.
At 20:55, one of the McCanns' dinner companions, Matthew Oldfield, approached the bedroom window of the children to check if he could hear any noise in the room
and at approximately 21:05/21:15 Gerry checked on the children. At 21:20 Jane Tanner noticed a man carrying a child going down the road next to the apartment of the McCanns.
Slightly further down the road, Gerry was chatting to Jeremy Wilkins, whom he had met at the resort, and neither noticed Tanner as she walked past them to join the rest of the group at the tapas restaurant.[16] At 21:30 Matthew Oldfield went to check the children but saw only the twins through the open bedroom door.[17]
