this is how it really happened. >> kate and gerry mccann were a british couple, normal couple, middle upper class. >> clap your hands together, 1, 2, 3. >> kate and gerry have twins. they were very young. madeleine was almost 4. madeleine mccann is a particularly beautiful child. she talked a lot. she was very lively. she liked to play. >> santa must have bring all these toys! >> she looks like kate, but she's got mccann personality. and if you've seen the rest of my family -- >> she's loud. >> yeah, she's loud. and she's a real extravert. and for one so young, she can express herself so well. >> madeleine had a stuffed animal that she called cuddle

cat. >> she adored and she was never without. >> kate and gerry, they were hard workers, wanted to go on a great vacation with their three children and with seven of their friends. and between the seven friends, they had five children. >> oopsie, you all right? >> it's the first time i'd ever been to portugal, but all the family and friends i knew that have been there said it's, you know, it's a lovely country, and it's really safe and it's for families. >> cheer up, gerry. we're on holiday. >> praia da luz -- it's this idyllic place. it's beautiful. it's marvelous. >> the ocean club is a very family-friendly place. it has a swimming pool. it has a tennis court where jerry mccann liked to play.

>> they'd go to the beach. >> they had this tapas restaurant and just tranquil places to walk. apartment 5a, where the mccann family was staying, was on the ground floor and right next to a street. >> the window was easily accessible for everybody who passed. >> the first five days of the mccann family vacation was a lot of fun. they were having a great time. but on may 3rd, madeleine seemed distressed. >> madeleine mccann was upset because she was being left alone with her brother and sister systematically through that week, and she was complaining, herself, to kate, saying that she didn't like to be left alone. >> kate, gerry, and their friends came up with a routine where they would be able to go out nearby and be without the kids, but not be too far away. >> we've always had a routine with the kids. twins usually went to bed about 7:00. and madeleine used to have a

little bit extra time. pretty much took them into the bedroom and read them a story and tucked them into the cots and madeleine into bed. and we got changed and ready, and we'd arranged to have dinner with our friends. >> they would leave the kids in the apartments by themselves. >> they decided to go to the tapas bar with their close friends and have dinner. >> they had a reservation for this table, where they could see the apartments. >> that restaurant where they used to go was a straight shot across the swimming pool from the apartment where their children were. >> it's only about 50 meters away. for me, you know, if your children are asleep upstairs in the bedroom and you're dining in the garden, you're out of sight, and you can't hear them. and that's the similar thing to me. >> and they had instituted an agreement that every half-hour or so, one of them would check on their children.

>> one person from the group would leave the table, go through the apartments, and then go back to the restaurant, just to check if everything was all right. >> if you've been to the ocean club, it is completely understandable that you would leave your children alone in this apartment because it's so close. >> it's very common in many parts of europe, you see strollers outside restaurants and babies in the strollers while the parents are in the restaurant. it's not unusual. on may 3, 2007, it was the second-to-last day of their vacation. >> madeleine went to the day care center. so did the little ones. >> the children had been swimming in the pool. madeleine told her mom, "this is one of the best days i've ever had." >> she tends to be the ringleader with the younger kids. and during the holiday, she was the oldest of the eight children here. and she just loved every minute. every waking minute, she was having a ball. >> but it's possible they were

being watched. someone was watching them, and somebody was watching madeleine mccann. >> i'd played tennis that evening, and kate had got the kids ready. >> they gave dinner to the kids and they put them to bed at around half past 7:00. >> we kind of had time to sit down and just chill for half an hour before we went out. >> kate was pretty sure that the window and the shutters were closed when they left the apartment to go to have dinner. >> and around 8:30, they then met their seven friends at the tapas restaurant. >> gerry mccann took his turn and went to check on all the kids. >> and when he got to his own apartment, he said that the bedroom door wasn't as they'd left. >> he and kate left the bedroom door slightly open before they left for dinner. >> the door was ajar, but it's

wider open when he gets there. >> but he didn't think anything of it. in fact, he hardly even noticed it. he saw madeleine in her bed with her cuddle cat, and he saw the twins in their bed. and everybody seemed safe, and he left. >> at 9:30, kate's about to go to check on the children. another parent offers to do it for her. so he goes back to check on the kids. >> he went by the mccanns' apartment. >> but doesn't actually go into the room. >> he peered through the door and he saw the sleeping twins. but due to the angle of the door, he did not see madeleine directly. of course, he just assumed she was sleeping. >> well, i went back to do a check at 10:00. i went through the patio doors at the back. i just noticed that the door to the children's bedroom was quite

far open. so i went to close over the children's door, and just as i was about to close it, a gust of wind shut it. and then i went back just to open the door again a little bit. just glanced at madeleine's bed, which was by the wall, and it was really dark, and i couldn't quite make her out. and then i thought, "so has she gone through to our bedroom?" and, you know, that would explain why the door was open, as well. so i just quickly looked in our room. and she wasn't there, and that was probably the first time that panic starts to build. so then, obviously, i ran back into her room and, um, just as i did that, there was -- the curtains, which were closed, just kind of blew open. and as they did that, i noticed that the shutter was open, the window was open. >> that was obviously the moment that all hell broke loose.

she had been taken. every minute felt like an hour, and then every hour felt, you know, like a day. >> i mean, you can't -- any parent can imagine, but will probably never be able to truly feel that desperation, really, that fear. >> the mccanns felt very strongly that the right things weren't being done fast enough to find their child. gerry was calling everybody he knew. he was weeping to his sister. they knew that she was gone. >> when i've arrived, i saw what i've never seen in my life. a lot of british reporters, a lot of cameras coming from abroad. it's not typical in portugal. >> there were police vans, journalists, television cars, you know, with antennas to do the live broadcasts. >> there are camera crews from right across europe.

portuguese police and help us get her back safely. >> they were in distress, especially kate. she was on the point of crying. >> please, if you have madeleine, let her come home to her mommy, daddy, brother, and sister. >> one of the aspects of this investigation which people felt could help her be identified and found is that one of her eyes was a bit unusual. it had a mark on it. so authorities were hoping that could help get her return facilitated. we saw so many small children, and i kept thinking, "is that madeleine?" if you saw a little blond girl, you would think, "is that her?" hopefully this could end up being a happy ending. >> she saw a man carrying a child across the street, into the night. >> it sounded suspicious. it sounded like a lead.

we need to do everything possible to help the police with their inquiries in finding her. if you have seen -- >> madeleine became one of the most-covered missing persons in modern history. there were comparisons of the press coverage surrounding her disappearance to the death of princess diana. >> the pope talked with madeleine's parents at the end of a weekly general audience, but it was a photo opportunity in which their anguish was plain to see. the pope now the latest player in a relentless media campaign that has grown beyond the borders of england and portugal. >> with all this publicity, tips were pouring in from all over the world. >> there have been 400 sightings of madeleine reported since she disappeared. >> belgian police described a reported sighting of madeleine mccann at this cafe near the dutch border as serious. >> one of the leads that came out in the weeks after madeleine's disappearance was that someone claimed to have

seen a girl that looked like madeleine in a gas station. >> by the time that the investigators got there, the tape in the petrol station had been wiped. there was another sighting of maddie in the rif mountains in morocco, blond-haired, blue-eyed girl being carried. >> when you looked at this photo, the girl, it was uncanny. she looked just like madeleine mccann. everyone felt, "this has to be her." >> tonight, a journalist from the evening standard, a newspaper here in london, believes he has found her, and, indeed, she is not madeleine, while she bears a striking resemblance to madeleine. >> oddly, all this attention worldwide had its dark side, and the mccanns eventually became targets of resentment. >> i do believe that some of that animosity was because these parents were very successful. kate, for example, like her husband, was a doctor. pretty woman, blond.

and people took it out on her that she had all those qualities. one thing that worked against madeleine's parents is that they didn't seem very emotional, kate or gerry. >> these are doctors. they have to give bad news to people on a daily basis. yeah, so these are people who are used to dealing with emotions. >> kate mccann, particularly, was told by child-abduction experts, "do not let anyone see you cry in public, because whoever took madeleine mccann might get off on that." the result of that was, of course, the newspapers and the television stations were going, "a normal mother would be weeping if her child was abducted." well, she couldn't weep. she was told her kid was at risk. she had to be strong. >> the fact that they had left their children in the room alone led some to believe these were already irresponsible people. >> in portugal, this is not normal.

so the questioning about their behavior started there. "oh, how can these people leave their kids alone? they were neglecting the danger." >> we think it's quite similar to, on a summer's evening at home, eating in your garden while the children are in your bed. you know, it's that close. >> but the claim that the parents had been dining right near their children might have been slightly exaggerated. >> it is absolutely true that it was sort of a straight shot to the tapas bar from the apartment, but you couldn't do it because there was a swimming pool in between. so you have to walk around on a public road before you get to the apartment. >> it hasn't happened yet, but, yes, legally, they could be charged with neglect. >> in june 2007, the portuguese newspaper sol published an article suggesting very strongly that the mccanns were responsible for their own

daughter's disappearance. >> this was an unsubstantiated theory that police coordinator goncalo amaral was privately advocating. and it all went back to the moment when kate discovered her daughter missing. >> kate mccann told police that madeleine was gone. the window to the bedroom, open. >> she says, in that moment, she saw the window slightly opened, and she says, "i didn't left it opened." but then, the policeman that went there said, "no, no, the window was shut, and she created the scene. she tried to create a new scenario to convince everybody of an abduction." >> this had people asking, "what really happened in apartment 5a that night?" >> can you just reassure people in britain that you've been completely candid with police about events on may the 3rd? >> we have left absolutely nothing out that we have known about at any point.

>> at the request of the portuguese police, who had been talking to a search expert from britain, they brought two dogs over. one of them is trained to detect human remains, and the other is trained to detect human blood. so they were brought over and sent into the apartment. >> what the dogs found was described as something shocking. >> there have been some traces of blood found in the apartment behind me. its investigative significance is not at all yet clear. that blood is being tested in a laboratory in britain. >> in the last week, portuguese media has been reporting blood traces found in the family's holiday apartment might indicate madeleine was killed there.

>> they felt very strongly, because the dogs sniffed the back of the couch and felt that there was something there, that maybe kate or gerry had hidden the body of their child in the apartment somewhere. >> kate and i strongly believe that madeleine was alive when she was taken from the apartment. obviously, what we don't know is what happened to her afterwards. >> the dogs also barked when they were taken to the garage where the mccanns' rental car was parked. the mccanns had rented that car weeks after the disappearance of madeleine. >> the dog that was trained to sense death, to perceive the scents of death, pointed to the car that the mccanns were using. >> it's obvious they must have put maddie's body in there, and the press went nuts. >> it was a very crazy moment. the public opinion turned

♪ kaye: all along, the mccanns have never been under a cloud of suspicion, until now. when children of tender years, such as madeleine, disappear, all along, the mccanns have never been under a cloud of suspicion, until now. >> when children of tender years, such as madeleine, disappear, around 75% of the time, the person responsible for

that is the parents. >> now the mccanns are under scrutiny like never before. >> what an amazing turn of events. >> there was also speculation that they gave the kids sleeping medication to put them to sleep so that they could go have their dinner at the tapas bar. and i think the thought that these parents might give something to their children, you know, led some people to believe that maybe these were bad people or not good parents. >> we all used to do that in england, legal drugs, obviously, that will help your child sleep. the thought process, at the time, was that they might have given her something stronger to effectively knock her out and that she might have then died. >> some thought that the reason the sniffer dog that was brought to the apartment started barking is because it apparently detected blood. >> some of the portuguese

investigators took the dogs' reaction almost as evidence that madeleine had died in the apartment and somehow her parents had concealed her death and then concealed her body. >> some people speculated the mccanns' friends assisted the mccanns in disposing the body and covering up the crime. this was a rumor members of the group vehemently denied. >> a family spokesperson gave a press briefing this morning saying that kate and gerry mccann have become very uncomfortable with the level of media scrutiny. however, they did address the one theory that madeleine had been killed by sleeping pills, saying that they categorically deny ever giving any sleeping pills to their children. >> philomena mccann, did your sister-in-law, kate, say anything to you about the possibility that she would be charged? >> she just said that it remains a possibility, but that was all she knew. >> kate mccann experienced hours and hours of interrogation by the portuguese police.

and guess what. most of them didn't speak english. >> they simply said to her, "if you can confess to killing madeleine, we can guarantee that you'll have two or three years in prison." and kate just was shocked by that. and she sees it as emotional blackmail, as intimidation. >> whistles and boos greeted kate mccann as she entered a portuguese police station for a second straight day of questioning. >> gerry. gerry! >> her husband, gerry, followed a short time later for his latest official interview. >> 11 hours yesterday for kate mccann, another five hours today. and for her husband, he's been spending about eight hours before he came out. >> their lawyer finally told them, "you don't have to continue this if you don't want to." and they did not. >> tonight, we can confirm both are no longer witnesses in the disappearance of their daughter,

madeleine. they are suspects. >> they have both been today declared arguidos with no bail conditions, and no charges have been brought against them. >> after they were declared suspects by the portuguese authorities, the mccanns made the decision to go back to the united kingdom. they may have been afraid that they were going to be arrested and felt like they needed to go back home. >> we have played no part in the disappearance of our lovely daughter, madeleine. >> while the mccanns urged authorities to keep looking for the actual perpetrator, lab results from the blood found in the apartment began coming in. >> firstly, the investigators thought this is madeleine's blood, but it turned out to be inconclusive. >> there were people who had lived in the apartment before the mccanns. one of them had a daughter who

had cut her chin. so that may have explained the presence of blood. >> ultimately, the decision was made that they were no longer suspects. why? 'cause there was no evidence against them. >> in the meantime, the fate of madeleine mccann remained as baffling as it did the day she disappeared. >> the mystery of what happened behind these shutters that fateful evening of may the 3rd is only increasing. >> everybody wants to know, where is madeleine? and the truth is, we don't know whether she's dead or alive. and we don't know what the headline is going to be tomorrow. >> things started to pour out, strange things. >> there was a very deep, unknown reality in algarve that was hiding from the news. >> they were searching another well. they were searching another piece of forest. >> at least two other locations in the area may also be searched. >> with the help of the public, we have every chance of bringing closure to this case. >> now there's a new suspect in

her disappearance. >> he's a deeply, deeply troubling man, a very dangerous individual. >> the local prosecutor also says that children's bathing suits were found on the premises. >> there was a person. there was a face. there is a profile. >> the mccanns are finally cleared of suspicion in the disappearance of their daughter, madeleine, but they are no closer to finding her than the night she went missing. shocking revelations, terrifying theories, and a mysterious lead that may finally hold the answers -- that's next, in part two. i'm jesse l martin. thanks for watching. good night. one, two, three.
