that's our climax there, i think. >> so to speak. >> don't miss anthony's show sunday 9:00 p.m. eastern and pacific. that's it for us. cnn special report "missing, madeleine mccann," starts now. one more big smile. that's pretty. >> the face of little madeleine mccann captured the world's attention. five days into their tranquil get away, tragedy struck. >> such is under way for a 3-year-old british girl. >> please, if you have madeleine, let her come home. >> the high profile, worldwide search. >> i don't know where she could be. >> the shocking twists. police are focusing their

attention on two suspects, madeleine's mom and dad. the theories -- >> somebody know what's happened. >> and the unsettling questions. >> the not knowing is what kills you. the not knowing. >> all eyes turn to the sleepy seaside village. >> my answer to the mccannes, there's still hope. >> cnn special report "missing madeleine mccann." >> praia da luz is one of the villages in portugal that had just been a fishing village. >> it attracts a lot of tourists from germany, holland, the uk. >> it's an easy, safe, relaxed place. a few restaurants, beautiful beach. just got everything that a family would want.

>> in late april 2007, along with three other families, kate and gerry mccann, their 2-year-old twins shawn and emily, and nearly 4-year-old daughter madeleine, traveled on spring holiday to picturesque praia da luz, portugal. each family remitted an apartment at the ocean club, a small resort in the heart of the village. >> it's pretty open. you've got a pool, the restaurant where they all went. >> with nine adults and a combined eight children, their party was hard to miss. all four of their rented apartments were clustered together in block five. >> and this was their apartment on the corner here. >> 5-a. >> julian is a private investigator. he says the location of the mccann's flat put them at risk. what made them more vulnerable?

>> because it niece the corner and there's a lot of places that you can be watching the apartment without being noticed. >> but from the mccann's view, the location of apartment 5-a had all the makings of a perfect family retreat. >> the first days of their vacation went exceptionally well, probably just as they had hop hoped. >> they both enjoy running and tennis, and the resort offered them all of those options. >> it offered plenty of options for the children, as well. madeleine mccann spent most of her days with the kid's club, under the supervision of resort personnel. however, at night, the mccann's opted out of the ocean club's child care. >> the mccann party made the decision that that might be disruptive to their children's sleep patterns. so they thought we can just do this all ourselves. >> at 8:30 every night after putting their kids to bed, they

joined their friends for dinner, while the children were all left alone, sleeping in their respective apartments. >> so they decided to mount a half hour checking system of all of their children. so one member of the group would get up and go and check, and check on all their children, come back. another one would go every half hour. >> it just felt so safe. it was a family resort. >> for me, if your children are asleep upstairs in a bedroom and you're dining in the garden, you're out of sight and you can't hear them. >> we measured it. where they were having dinner was about 60 yards from apartment 5-a on the corner there. >> could they see the apartment from there? >> they could see it, but they couldn't see the windows, because there's a lot of bushes and everything. >> it was across the pool and everything, but you could see the doors. >> sliding glass doors they had left unlocked. >> they left them unlocked

because they wanted the access for check, and they were going in every half hour. it's a judgment call. >> a judgment call that would haunt the mccanns forever. >> all i could say, if i thought there was any risk at all, it wouldn't have happened. >> it is that environment where you feel so safe, so secure, so at ease. was it right? we know the answer to that now, don't we? >> may 6 began as a typical vacation day. >> kate and gerry mccann got to spend some time together, playing tennis, lounging at the pool. in the evening, when gerry mccann went to take a tennis lesson, kate picked up the children at the kid's club and brought them back to the apartment to get them ready for

bed. >> they sat on the patio, had their first glass of wine, got ready and went down to the restaurant. kate told one of her friends about the troubling incident with madeleine during the morning. >> that morning at breakfast, madeleine had asked her parents a startling question. >> she said, mummy, when shawn and i cried last night, why didn't you come? did that mean that they were upset by something the previous night? >> they wondered if they should go out again that evening. but madeleine seemed entirely at ease. they certainly had no intimation or reason to think it could be anything more sinister. >> they then carried on with the evening, and began the process of the regular checks on the children that they had been doing all week. >> according to the timeline provided by the group at dinner,

gerry mccann conducted a check at roughly 9:05 p.m. >> so i came in and madeleine was just in the bed and the covers were folded down and she had her blanket by her head. it's terrible, because i had one of those really proud father moments where i just thought, you know, you're absolutely beautiful and i love you. >> on his way back down to dinner, jerry spotted an aquan dance and stopped for a chat when another parent jane tanner walked by. that was about 9:15 p.m. jane made her way up this treat and that's when she said she noticed a man walking along that street heading that direction. she described him as carrying a child in his arms.

a child that was about the same age as madeleine mccann, didn't have any shoes on, and wearing pink pajamas very similar to madeleine's pajamas. at the time, she didn't think much of it. then about 9:30, 9:25, matthew olefield was going upstairs and said to kate, i'll go and check on your three. he went into the mccann's apartment. he went to the door of the children's bedroom but did not go in. >> he looked in and saw the twins through the door in cots but he didn't put his head around to the left where he would have seen if madeleine was there or not. i'm sure it's something he regrets massively. >> less than 30 minutes later, it was kate mccann's turn. >> i went back at 10:00 and noticed that the door to the children's bedroom was quite far open, and just as i was about to

close it, it was like a gust of wind shut it. >> her heart sank then, because everything was wrong. >> i went back to open the door just a little bit. just as i said, i noticed that the shutter was up and the window was open. >> and then she saw madeleine's bed was empty. >> what did you think at that moment? >> someone has taken her. >> please, if you have madeleine, let her come home to her mummy, daddy, brother and sister. >> the search for madeleine begins, next. ♪ ♪

>> we had only less than 100 in all of the country. >> yet according to british investigators, in the four months leading up to madeleine's disappearance, burglaries had quadrupled in the village where the mccanns were staying. >> one of the theorys is this could have been a burglary gone wrong. do you believe that's possible? >> no. you go inside to pick up a wallet. you don't go out with a kid. what the hell are you going to do with a kid? >> by the fall of 2013, scotland yard wasn't publicly ready to rule anything out, except for one critical part of their timeline. according to redwood, the man jane tanner described seeing the

night madeleine vanished was actually this man, an innocent father who was carrying his own child home from a nursery around that same time. >> we believe in a convincing way this is not madeleine's abductor. >> and so he focused attention rather on another sighting. >> an irish family leaving dinner that night around 10:00 p.m. reported seeing a man carrying a child towards the ocean. >> but who that man was to this day is still unknown. >> that's the bigger question. >> precisely. >> another big question detectives were trying to answer -- were the mccanns being watched? there are two witnesses who say independent of one another that they saw what they described as a very ugly, pock marked or spotty skinned man watching apartment 5-a. >> another witness reported having seen suspicious men on a

balcony near the mccann's apartment just hours before madeleine disappeared. >> meanwhile, an upstairs neighbor saw another mann acting very suspiciously in the little pathway between the pool garden and apartment 5-a. >> and there was more. british police released a sketch of one of the men they say approached nearby apartments, asking residents for donations to a local orphanage. >> now, there was no such orphanage. so clearly these men were involved in some kind of a crime. possibly just burglary, but possibly something else. >> we've got a lot of work to do. we've also done a lot of work. we are wholly committed to making a difference in this case. we're fighting for madeleine mccann. >> a fight that has lasted far longer than any had hoped. >> there's no evidence that she's dead. so certainly from my point of

have just arrived for the questioning of 11 key witnesses. >> sorry, i have no comments for you. >> reporter: after shelving the case six years earlier the portuguese police have recently joined scotland yard and reopened their own investigation. portuguese law enforcement officials confirming british police want to interview three individuals. >> they have identified three known burglars, known thieves who were operating near the ocean club very close to the time that madeleine had disappeared. >> reporter: those men were questioned but never charged. in the summer of 2014, officials returned to conduct a week-long ground search. >> the clear implication was that they were looking for perhaps human remains.

>> the visuals of it were police searching on the ground, this is dreadful, but they were there to rule things out. has that been double checked? has this been checked? did you do this? did you do that? >> reporter: another step in a painful process of elimination. do the mccanns get their hopes up with every move? >> they learned long ago not to get their hopes up because, sadly, there have been far too many disappointments. >> reporter: since 2007, there have been a staggering 9,000 reported sightings of mad len. scott atlanta yard alone has looked at nearly 600 individuals, poured over 40,000 documents and spent more than $15 million in their search for madeleine. >> there has been a fair amount of criticism about how much money has been spent on the investigation into finding madeleine mccann, also they have been criticized for getting preferential treatment by british thorpts.

what is your response to that? >> if those people who are doing the criticism, if it was their child that was missing, would they say the same? they would wish that every other missing child case would get a similar level of resources. >> reporter: but by the fall of 2015, those resources were dropped significantly when scotland yard reduced its staffing from 30 officers down to just four. >> what has been done is just as important but on a tighter more managed scale. this sort of work takes time and, of course as time goes on, it gets harder, but it's not impossible. >> back home in england, a decade after their nightmare began, the mccanns faced another somber milestone. ten years come and gone without any sign of their daughter. >> inevitably, on our anniversary, they are by far the

hardest to face by for. >> it's important, though, because despite how difficult these days are, just keep income mind how much progress we have made, although there is no evidence to give us any negative news that hope is still there. >> they have made such an emphasis of the point that time is the enemy. we've done too good of a job of doing that, because now the public thinks, if you don't recover a child in the first days or weeks or months, that there is no hope. and there are a growing number of cases that demonstrate that there is hope. >> we get lucky. we get kids back alive. but the not knowing is what kills you. the not knowing. >> reporter: because without knowing, you are forced to consider the most heart breaking possibilities. >> i think the major scenario, because the data tells us, is that whoever took her, took her
