her crib in the middle of the night in this quiet kansas city neighborhood, right from the start, police have said the parents of little lisa irwin were cooperating fully with the investigation. in fact, it was on the recommendation of the police that jeremy irwin and his fiance deborah bradley first went public with their anguished pleas for their daughter's return. >> please. bring her home. our two other boys are waiting for her, please. >> reporter: but today, the baby's mother revealed that just hours after her daughter was reported missing, police subjected her to an 11-hour interrogation. did they accuse you directly? >> oh, yeah. >> reporter: what did they say? >> you killed her. you know where she's at. give everybody else closure, you know you did it. and i kept saying no, that's not possible, no. no. no, no. >> reporter: she says after hours of grilling, she finally volunteered to take a polygraph.

>> reporter: almost immediately, police dismantled the mobile command center they set up from which they'd been coordinating searches of homes, bigz businesses and even the city's sewers. and they took down the crime scene tape at the family home. late today, abc news gained exclusive access inside the irwin family home. incredible to be in this room which has been the subject of so much discussion in recent days. this is the crib where lisa's mother says she put her to sleep at roughly 10:30 on monday night. that's the last time her mother says she saw the child. looking around the room, so many poignant details. this is her hand print and her foot print. when lisa's father jeremy came home at 4:00 in the morning, he noticed the front door was unlocked, which he considered to be highly unusual. as he made his way through the house, he noticed that all the lights were on. he also noticed that this window, which faces the front side of the house, had been tampered with. this is a story that, as we

learned today, the police appear to find highly suspect. what is their theory? are they saying, look, your story is hard to believe, this happened on the one night that you happened to be working an overnight shift and the one night that you happened to leave the front door unlocked? >> my response is, you know, anything can happen. >> reporter: can you see how -- >> oh, i know, i understand. i totally understand. which is why i have cooperated and will continue to cooperate. our focus is lisa. lisa. >> reporter: in those marathon interrogations, it was apparently not just lisa's mother under the microscope. she says detectives also tried and failed to get her to turn on her fiance. did you have anything to do with lisa's disappearance? >> no, of course not. i mean, i love her more than anything. we love her more than anything. >> reporter: today, we asked the kansas city police about the

questioning of lisa irwin's parents. lisa's mother says your detectives are accusing her of being involved in the disappearance of her child. do you believe she was involved? >> well, i can't xhont on the details of the investigation. she's free to talk about whatever she would like. i can't go into details. >> reporter: i would man given the history of this sort of crime, you have to look at the fami family. >> we're looking at everything. we have no leads. >> if anybody knows anything, the smallest tip, no matter how insignificant you might think it is, that could bring our lisa home, please do not hesitate to call. so we can find her -- so we can find baby lisa. >> reporter: their relationship with investigators may be fraying, but under this immense strain, their relationship with one another is showing no cracks at all. for "nightline" this is dan harris in kansas city. >> we will continue to watch this case closely.

women swooning all over the world. that voice was a crucial part of his appeal as the charmer who sweeps julia roberts off her feet in "eat, pray, love." and as the smoldering artist -- >> drink good wine, we'll make love. >> reporter: in "vicky christina barcelona," this time, romancing his real-life wife, penelope cruz, mother of his son, leo. but he is probably best known for the very unattractive hair cut he sported in "no country for old men." a performance that won him an oscar. he dedicated his award to his mother. that's right. he's a heart tlohrob who loves s momma. >> i cannot even put in words because i don't know how to express it.

i'm an actor because my mother. since i was born, i was going to theater plays and i would be backstage watching the whole process from the moment she comes into the room, she makes up and she goes to stage and then she becomes a different person. that always amazed me. >> reporter: not only did she inspire his art, she planted the seeds of a social conscience. which is why he's in new york right now, to take up a cause. >> people might have the right to speak. >> reporter: it's not unusual to see a celebrity do that, but this one is pretty obscure. his issue, the people of the western sahara. it's a disputed territory in north africa, and it once was a colony of spain which is bardem's homeland. but when spain moved out in the 1970s, morocco moved in and it sparked a war over who would control it. the result is a serious refugee crisis and a people without any say in their national identity.

and nobody wants to do anything about it. >> hot potato. >> reporter: how do you say that in spanish? [ speaking spanish ] >> is it the same? >> reporter: nobody wants to hold it. and nobody knows much about it and i'm not sure people care. why have you thrown yourself into this? >> i took a trip to the camps and i saw it with my own eyes and i realized how much injustice are in those camps. when you have the relationship with them in the camps, it has an impact on you. it goes back to your own roots, which is as a spaniard, as a spanish person. i would really need to do something for these people. >> reporter: do you feel a bit of national guilt? i mean, is it something that you feel the country needs to answer for? >> national guilt is a good way to put it, especially being the christian country that we are, the catholic country that we are. >> reporter: are you excited about today?

>> i am. >> reporter: different, a little different. >> different, but important. >> reporter: then, it was onto the united nations. >> it is a great injustice, a violation of international law. >> reporter: as well as petitioning the u.n., he's making a documentary about the western issahara, to highlight e humans rights abuses. >> there's a moment where you ask yourself, how can i help? they ask me, are you a doctor? i said no. are you a nurse? no. do you know logistics? no. so what are you, an actor, so keep on doing movies. when we come back from our field trips, we feel great watching your movies. and you go, okay. >> reporter: that's your contribution. >> exactly. so, your contribution is about knowing what you know to do best. in this case, movie-making. >> reporter: but being an activist won't keep him from being an actor. you are known for some of the great films you've done, "no country for old men," -- >> this is the opposite of being

a nice person. >> reporter: exactly. real villains. tell me the next villain you're going to play in james bond. >> i'm very excited because my friends got me to watch the movies and i saw all of them to, to place that is going to be fun. they choose me to play men that i cannot give you many details. >> reporter: but on the western sahara, he wants to make sure he is heard loud and clear, even through that famous accent. >> i'm going to try to vocalize a lot. because they have to understand what i have to say. >> reporter: give me an example, how are you going to do it? >> opening the mouth and twisting the tongue. >> reporter: i'm christiane amanpour for "nightline" in new york. >> man with passion in his heart. thank you for watching abc news. we hope you'll tune into "good morning america." have a terrific weekend, america. >> dicky: tonight on "jimmy kimmel live" -- >> jimmy: are you prepared to become the second fastest man in the world? >> that's not going to happen.
