>> a lot of families. we have a lot of parks out there. good schools. >> saturday, may 31st, 2014. it was one of our first nice weather days we had on a saturday. sunny, 72 degrees. >> gorgeous day out. i thought, "well, the earlier i get in, the earlier i get out and put in my eight." >> my first call of the day it was a pretty easy call. the family video store is one of our local ma and pa shops. they rent videos. one of the only ones left in the area that i'm aware of. on their marquee they had a phrase that was supposed to say "hot hit sale" and someone had rearranged the letters overnight to a very inappropriate message. i was kind of chuckling about it. i was just about to take a photo to send to my wife so she could get a little chuckle out of it. just as i was trying to take my phone out, over my radio i heard that a 12-year-old girl had been

stabbed about a mile and a half away from this location. >> i'm transferring over a caller on big bend. he came upon a 12-year-old female. she appears to be stabbed. >> she appears to be what? >> stabbed. >> stabbed? >> correct. >> initially, my thoughts were this isn't really what this is. i'm thinking, this girl probably scratched herself. she fell down off her bike. this girl did not get stabbed. >> greg steinberg was on his bicycle. only on this saturday he chose to take a different route. and that's when he found payton. >> i quick got out my cellphone. i was shaking. and dialed 911. and i just stayed with 911. >> reporter: she was right here in the grass. >> exactly. >> reporter: but you had no idea how many times she'd actually been stabbed? >> no. >> okay, sir, are you with her right now? >> yeah. >> is she awake? >> she's awake. >> is there any bleeding gng on? >> her clothing has got blood on it. >> i offered her water because i

had a water bottle on my bike. the other thing she said was she's having trouble breathing. >> reporter: he knew this was a little girl in trouble and when she began to tell him what had happened to her he was in disbelief. >> okay, he's coming. who did that to you? >> the road she was located on was big bend road. at the dead end of that. participaton wasn't moving a whole lot. as i approached her i said hi, i'm officer dan, are you okay? and she said no. i helps on the way. stay right where you are." as i got closer i started to see a little bit more blood and the closer i got the more blood i saw. >> reporter: somehow she'd been able to pull herself out of those woods. and in another moment of strength, she was able to communicate with him. >> i asked her, "who did this?" and she told me her friend morgan. i then asked her "where did this happen?" and she told me that it happened in the woods. >> reporter: she was the first

one to reveal that it was morgan, her best friend, who was behind this. >> morgan is 12. morgan didn't do this is what's going through my head. >> reporter: now police decide they've got to go to morgan geyser's house to figure out how this happened. >> not only were there police in my living room, but they were wearing riot gear. >> i thought, "what in the heck would make somebody do this?" >> reporter: was it hard for you to wrap your head around what had been done to you?

♪ do you feel like you're a survivor? >> yeah. i shouldn't be alive. i really shouldn't after what happened. >> reporter: paramedics get to the scene and even they are stunned at what they're seeing. >> a 12-year-old girl, she'd been stabbed, you know, multiple times. >> they removed her clothing by cutting it off and got her on the gurney and into the ambulance. i could see multiple wounds on her. >> reporter: she was able to somehow communicate with them in that moment that this was a knife that had been used. >> they asked how long was the knife and she said that the knife was about like this. and she was talking about the blade, not the handle. >> i was waiting in the e.r. and payton was brought in by stretcher. the look on her face is something that i will never forget. she looked like she was in an extreme amount of pain.

>> so you bring her in here. >> reporter: one of the first people to see her is the e.r. doctor. he told me that her blood pressure was dangerously low, her heart was working in overdrive. i mean, this is a 12-year0old girl really struggling to survive. >> and when you looked at her it was immediately apparent she'd been stabbed multiple times? >> yeah. to her chest and abdomen and arm and leg. >> my first thought is i need to get some sort of information from her in case that she does die. i confirmed with her that morgan did the stabbing. i confirmed that she was in the woods at the time. and that there was another girl there at the time when this happened. >> reporter: when detective trussoni hears this, that she's been stabbed by her friends, she knows she has got to get to payton's mom stacie, and right away. >> it's never fun making a notification to anybody, because when they see us they know it's

not good. >> the first thing that goes through my mind is something has happened to somebody that i love. because that's the only reason a uniformed officer and a detective comes to your house on a saturday morning. >> she was very calm, very collected. she knew that something was going on. i don't think she knew exactly to what extent it was. >> they said, "is payton home?" and i said, "no." and they said, "was she at a sleepover last night?" and i said, "yeah, she was." >> i explained to her that she's alive but she has been stabbed. >> i said, "well, are -- is it -- are the wounds superficial"? and they said, "well, we really don't know. but call your husband, find somebody to take care of your son." >> she just went right up there, and she made it in time before payton went into surgery. >> i walked into the trauma room that she was in. and she was pale as a ghost. she was terrified. she was crying. she couldn't breathe.

and all i hear is "there's five on her arm. there's seven on her leg." and i'm thinking, what? seven? what? and one of the nurses says, "all right, i count 19." and then the second nurse said, "i count 19 as well." what? 19? what -- there's no way. >> reporter: there were so many of them that they were carefully going over payton's body to make sure they hadn't missed one. stacie says she will never forget. >> i said, "you're going to be okay. it's going to be fine." but i could see that she was covered. her arms and her legs and her abdomen, they were covered in stab wounds. >> does it seem surreal even to this day? >> yeah, it does. i mean, there are definitely like moments from that day just -- they're burned into my mind. i'll never forget them. >> describe the moment you first see her. >> reporter: the surgeon who was there that day when he was looking at the wounds and in particular the stab wound to the

chest, he told me that had it been the width of a human hair deeper, that stab wound, that she wouldn't be here today. >> the knife stopped at the wall of the artery. >> and had it not? >> had it not, she would have had a major heart attack from the amount of bleeding and probably died within a minute or two. >> reporter: and now police decide they've got to go to morgan geyser's house to figure out how this happened, what was behind this. >> they asked me where's morgan? i said, "she's at the park with her friends." >> angie geyser told us that there was three girls, a third girl named anissa, and the three girls left early in the morning for the park and they hadn't heard from them since. >> they searched the house, and i just kept asking what happened, what's going on. and they wouldn't tell me, other than to say there had been an incident at the park and one of the girls was hurt. >> the thing that really struck me is the way that she portrayed her daughter to be. that she was totally normal. she was a good kid. and she thought that this was

totally out of character for morgan to be involved in anything like this. >> after we found out that there was this third girl, anissa, that was there, we were able to get in contact with anissa's dad. >> bill, my ex-husband, called me and told me to get to the condo as soon as possible, the police are there looking for anissa. >> we searched the house. we didn't find either of the girls there. >> reporter: where are these other two girls? they know those two girls were in the woods, but they cannot be found. >> where is my daughter? that's the only thought i had in my head. i looked at her cell phone, checked all of her text messages trying to figure out the people that she called and contacted last. >> kristi weier said that she had found anissa's cell phone and found a particularly disturbing message that was on there. >> i found basically her goodbye notes. >> i thought that they were in grave danger and that we may find these girls dead.

>> what was the meaning of this? we need to find these two girls. >> so what's going on with you? why do you think you're here today? >> reporter: it is a scene you rarely see -- two 12-year-old girls in separate interrogation rooms. >> and when she began explaining, i just remember going "this is the most unbelievable story i've ever heard." schools are having acrto cut sports.y, i'm tony the tiger and i'm on a mission to fix that. ♪ bring back the tigers. ♪ your mighty, mighty tigers.

the sadness or any of the bad things. they knew what each other had gone through, and they were going to be there for each other. >> initially, when we were first on scene, kristi weier, anissa's mom, had called me and said that she had found anissa's cell phone. >> i looked at her cell phone, checked all of her text messages and i found, basically, her goodbye notes. >> the message said, "this is my final wish to those who care. do not grieve my absence, but remember me for who i was. i love and cherish you and wouldn't do you harm." >> it then changed my thoughts from abduction to running away. >> it was about 2:53 in the afternoon. i had gotten a message that the sheriff's department had located the girls on the side of i-94. >> they have found those two girls, i'm told, around 12 years old. >> they were sitting on the side of the freeway.

>> by the time we found them, they had walked about five hours and made it to the north end of our city. and they were transported back to our police department. >> the detective told us that they were taking them to the police station to ask them some questions. i remember talking on the way how we were going to punish morgan for this. i mean, we just had no idea how serious it was. >> when they brought the girls back, payton was actually still in surgery and we did not know if she was going to make it at this point. so we didn't know if this was going to be a homicide investigation or what this was going to turn out to be. >> they were kind of dirty, covered in some stains. their demeanor was very calm. they seemed kind of meek, if you will. >> reporter: it is a scene you rarely see. in fact, i don't know the last

time i have seen two 12-year-old girls in separate interrogation rooms about to describe in excruciating detail what it is that played out in the woods. >> i could tell that they were somewhat scared. at least anissa was showing me that emotion. >> your parents know that you're here talking to me, okay? and -- >> are they scared? >> they're glad -- they're so glad that you're safe. >> i did notice that she had a blood stain on the front of her shirt, and she was wearing two shirts. and i asked her, "are you okay? >> can you just stand up and, kind of stand -- there you go. just, like -- >> right there. >> okay. let's just -- >> and it's on the white shirt underneath that. >> and it's on the shirt underneath it, too? >> uh-huh. >> okay. and what is your name? >> anissa weier. >> anissa, okay. okay, just get -- there you go. all right. >> morgan seemed like she was very calm. very relaxed. i mean, she's at a police department and she's covered in blood.

and this is like a normal day for her like. >> morgan, we're going to take some photographs of you right now. >> okay. >> do you mind just standing up, maybe? all right. just stand up like that. perfect. what was your name again? >> morgan. >> okay, morgan. >> do you know what happened to bella? >> morgan called payton by the name of bella. >> she said it was a nickname because there was another girl named payton. >> is she dead? >> i don't know. she was taken to the hospital. >> what? i was just wondering. >> she was very nonchalant. it didn't seem like it really concerned her too much if she was dead or alive. >> the first thing i needed to do in order to talk to anissa, and find out what happened, i needed to read to her her miranda rights. >> you have the right to remain silent. if you try to give up that right, anything you say may be used against you in court.

>> apart from the law, it is jarring to see 12-year-olds being interrogated without their parents present. >> if you cannot afford an attorney, one will be provided to you by the court. understanding these rights, are you willing to sit down and talk to me a little today? >> here in the state of wisconsin a child can be interrogated without the presence of their parent or guardian being in the room. at that time i did not know that. >> we find that people are more truthful when they don't have their parents present. >> i need to you initial right there and sign right there. >> i thought that she really did understand what her rights were and made a knowledgeable decision to waive those rights. >> i've never gone into an interview so blind as i have in this one. i thought that maybe this was all about a boy, this was a fight about a boy. >> i still don't know what happened. and i don't know who did what. and i need to know that today. okay? >> we didn't know what these girls were going to tell us.

playing on playground with the slender man in the background, and the other one was a sort of a more pensive picture. the story that went with it sort of explained that these were photos that were taken right before a bunch of children had gone missing and that was it. >> who's slender man? >> he's -- he's this tall, faceless man who preys on children. >> he can be anywhere from six feet to 14 feet tall. he's a tall guy who constantly wears a suit. he doesn't have a face. his skin is white. >> anissa actually was the first one who had found slender man in the creepypasta wikis, the stories that were out there about slender man. >> at his own will, he can, like, explode these tendrils from his back and, like, strangle his victims. and from what the creepypasta wiki said, he targets children most. >> who tells you about him? >> he's everywhere. >> how do you know? >> because i've read so many things about him.

>> it sort of going down the rabbit hole of the internet. >> the idea became very crowdsourced and everybody loved it. and they all started jumping in. >> so this is a little concept art i drew of slender man. >> people were making new images, new photos. the first slender video game came out. >> he's never played it before so he's going to play it for the first time.

around, there's no critical thinking around, and so they can get carried away. >> reporter: do you think looking back that they couldn't differentiate between what was fictional and what was real? >> yeah. i think that all of those fake pictures that were going around, i think very strongly that they believed all of it was real. >> i actually thought that he was real. 'cause i saw him. we were like talking on the bus. i look out the window and i see this supposed thing standing like this, with tendrils, looks exactly like a tree. there and gone like that. >> the facelessness of the character makes him infinitely interpretable. there were a lot of different variations out there, and the girls found a version that complemented the things that they wanted to believe.

>> anissa explained to me that to prove yourself worthy to slender you would have to kill somebody. >> morgan said, "we have to kill bella." >> then they were going to walk to the nicolet forest to try to find slender man. >> morgan found out that slender has this big mansion in the middle of nicolet national park. >> what needed to make this happen, that for them to live in this mansion was to kill somebody. and that idea came from morgan. and my thought was, "is she doing this for morgan?" >> reporter: what was morgan like when you met her? >> she seemed a little lonely. controlling sometimes, but i just went with it. >> reporter: at the time did you consider her your best friend? >> yeah. >> she was my only friend for a long time. >> so why would you hurt your only friend? >> it was necessary. >> it wasn't until sixth grade that anissa came into the picture. >> anissa was moving to a new

school, so she didn't know anybody. their interests were similar with regards to what they like to read. they were into horror stories. supernatural. >> we're so close, we're like sisters. >> they were lonely girls. they didn't have a lot of friends. came across i think to other students -- the best word i can think of is weird. >> reporter: were you ever really friends with anissa? >> no, not really. she was always cruel to me. i feel like she was jealous that morgan was friends with me and her. >> as morgan learned more about slender man, it came to dominate her thoughts. and she got closer to anissa and a little more distant from payton. >> i didn't really understand what we were doing, but i really didn't want to make anissa mad. it's hard enough to make friends. i don't want to lose someone over something like this. >> do you understand what it means to kill somebody? >> i mean, i've seen stories on the news, but i never fully understood what it meant to kill somebody till now.

♪ what did you think was going to happen after you stabbed payton? >> i don't really know. i figured that i'd get in trouble eventually, though, because mommy always says that whatever you do catches up to you eventually. and it did. >> about halfway during the interview with morgan, i got up and i took a little break. i went and met with detective trousonney and we sort of compared notes. >> i just remember looking at him going, "this is the most unbelievable story i've ever heard." >> who's ever heard of two 12-year-old girls planning for six months to kill one of their best friends? >> we had no idea how difficult it was not to tell anyone. we would all be together. it was a flawless plan, actually. >> i think they wanted to kill payton because they felt payton was accessible in that way.

you know, they didn't have a lot of friends. she was somebody that they would be able to get to be alone with. >> did you ever talk about killing bella in the bus, at the birthday party? >> we did sometimes, but we made sure we whispered. granted, the bus was really loud, but people are eavesdroppers. we used code words like for knife, we meant -- we used cracker. >> okay. >> and for the killing we would use words like itch. >> there were actually three plans that were devised to kill payton. >> morgan said that at her birthday party while bella was sleeping we were going to like duct tape her mouth shut, stab her in the neck and then leave. >> morgan was going to put on a set of headphones connected to her ipad and set an alarm to wake her up in the middle of the night, like 2:00 in the morning. she would wake up anissa. >> but we didn't stab her in

bed. we were too sleepy and tired to maybe -- we were at skateland. >> that was the original plan? >> yeah, until it changed. >> so 5:30 in the morning comes and they wake up and they get up, start playing with silly putty and playing with their ipad and playing dress-up. and while payton is putting on a pink princess dress, the two start talking and they start devising plan number two. >> morgan said, "hey, we could go to the park and kill her in one of the bathroom stalls." >> was bella around at that time? >> i - yeah. bella -- we were playing dress-up. and bella was putting on a costume in the bathroom. >> it's mind-boggling, how do you one minute want to play like a normal 12-year-old and then switch back to "oh wait, we're

going to kill her"? >> we asked morgan's mom if we could go down to the park 'cause we were gonna do it then in the bathroom stall and, like, sit her on the toilet. there was a drain for blood to go down. >> and when does she take the knife? >> she took it before we left. >> where did she get it from? >> her kitchen. >> so who left the house with it? >> i think anissa did. it was in the bag. >> to me she was trying to deflect the blame from herself back onto anissa. >> how did you know that she grabbed one? >> 'cause she showed it to me as we were walking to the park. >> morgan lifts up her jacket and shows anissa that she's got this knife in her waistband. >> what were you thinking? >> i was thinking, "dear god, is this really happening?" >> she told us we had to kill her. >> who did? >> anissa. >> there was a lot of deception in morgan's interview.

it seems like anissa is saying this is what happened but when you listen to morgan she always says, well, i think that anissa did it. i think this happened. >> i think anissa told me too. anissa might as well. i'm sort of foggy because i've been trying to block it out. >> they then walk to the park. they go into the bathroom at the park. >> they're in the bathroom stall and they're kind of passing the knife back and forth. >> from what i read on the computer, it's easier to kill people when they're either asleep or unconscious, and it's also easier if you do not look them in the eyes. >> anissa tells me that she actually tries to knock payton out. >> i kinda went like that to her forehead and banged her head up against the concrete. >> and you were doing this to knock her out so you guys could kill her in there? >> yeah. >> they lose their nerve.

they don't kill her at that point. they then go outside. >> they leave the bathroom and they start to walk through the park. and that's when plan three is devised. >> i say, "hey guys, why don't we go take a walk around the block?" and that's when i pointed out to morgan the trees and bushes and all that and say, "we can take her in there and do the deed." >> we led her there and tricked her. >> how did you trick her to get down there? >> we said that we were going to go bird watching. people who trust you become very gullible. and it was sort of sad. >> and once they got closer to the woods, they had suggested that they play a game of hide and seek. >> they walked deeper and deeper into the woods and then morgan said that she would go off and count, and that payton and anissa should go hide. >> she was gonna hide one place, i was gonna hide another. and then morgan and i were gonna

be like lionesses chasing down a zebra. i was gonna tackle her and then morgan was gonna do the stabbing. >> anissa passes the knife back to morgan and morgan's like, "all right, i'll do it only if you tell me when to do it." >> so i started walking away, and then like when i was five feet away i said, "now." i'm, like, i'm meant -- go ballistic, go crazy, make sure she's down. >> i couldn't believe these words were coming out of a 12-year-old's mouth. it's awful. >> what did you do next? >> i already told you. >> what was that? >> stab, stab, stab, stab, stab. >> in all my years of law enforcement, never heard anything like this. >> it's almost as if they are writing their own story. they're living their own creepypasta story. >> you'd look at that video and say, "see? she's bloodless. she's just cold-hearted.

she was going to kill." and othepeopleaid oh, she's so clearly disturbed. >> do you remember leaving the park to go to the woods? >> they just wanted to go on a walk. who could ever see something like this coming? like nobody. >> and you were 12 years old. >> exactly. oblivious. >> they made the wrong turn at each point to the point where it just was outcontrol. >> you just have to think about this locomotive that is just going down the tracks and there's no brakes on it. >> is it possible that we have that extremely rare thing going on here which is we just have an evil 12-year-old?

and we started talking with the girls that we really knew what was going on, that it was two 12-year-old girls that have planned for six months to kill their friend. >> you don't often see this with adults. and to have this happen between 12 year olds is absolutely horrifying. >> can i ask a question? >> yes. >> where is bella's body now? >> bella's at the hospital. >> okay. i thought it was still out there in the crime scene. >> did you think that she died? >> yes. >> she is alive. >> okay. >> reporter: have you ever watched any of those interrogations? >> i watched a little bit. >> reporter: what was your reaction? >> it was a little shocking to me to see that they had this big, huge plan that they had been working on for months. >> less than a week after the attack i was asked to go to the hospital to interview payton. she was very, very quiet.

we had to turn up the sound on the recording equipment really high just to get her voice. >> reporter: do you remember leaving the park to go to the woods? >> they just wanted to go on a walk. and i didn't think much of it. it's just a walk. it's in waukesha. like what bad stuff happens in waukesha, wisconsin? >> after we go into the woods, we say we're going to play hide and seek. >> anissa told me to lie on the ground and like cover myself in sticks and leaves and stuff but it was really just a trick. >> it took a long time through the interview to finally get her to say morgan's name or that morgan had even stabbed her. >> i give it back to her and say, "you do it. go ballistic." and she said, "okay, i'll go ballistic whenever -- when you say you want me to." >> reporter: when you hear them describe to investigators, anissa telling morgan just to do it. i think the word was, "go ballistic." >> oh, i remember that.

i do remember them chatting right next to me while i was just laying there. >> morgan said, "don't be afraid. i'm only a little kitty cat." and jumped on top of bella and stabbed her repeatedly. >> reporter: and do you remember when it started? >> kind of. i didn't feel anything because my body was in shock. and the adrenaline -- i didn't feel a thing. >> so at one point during the interview with morgan i specifically asked her about who stabbed payton. >> who stabbed her? >> both of us. >> who stabbed her first? >> how am i supposed to remember that? >> well, this is just pretty important. so just gotta try to concentrate. >> anissa or me. one of the two, of course.

but i don't know. >> morgan is the person that did all the stabbing. >> i asked payton how it stopped, and she simply said that morgan just stopped and stared at her. that both her and anissa for a while just stared at her with this blank stare. >> and then what happened? >> are you trying to do this over and over again to see if i tell the story differently? >> no, i'm just trying to make sure that i get it right. >> i thought that she was very aware of what was going on. actually, very sophisticated. >> after they stabbed her 19 times, they encourad her just to lay down in the woods and rest. but what they really wanted her to do was bleed out in the woods. >> reporter: and do you remember what you said to them? >> "i trusted you." and they told me to lay down, you'll lose blood slower. we're going to go get help. >> did she try to get up? you said that payton -- >> yeah, she tried to get up. she said that she couldn't see, she couldn't walk and that she couldn't breathe.

>> and they told her they were going to go get her help, but anissa flat out said we weren't getting her help. we wanted her to die." >> reporter: do you remember the moment they left you? >> i think i remember them running away. but i kind of just laid there for a minute. >> reporter: you walked out of the woods? >> i got up, grabbed a couple trees for support, i think. and then just walked until i hit a patch of grass where i could lay down. >> it's amazing that she had the strength to do that with the injuries that she had. when i told her that the girls were in custody, it seemed to give her a sense of relief. >> the girls were ultimately arrested for first-degree attempted homicide. that's a very serious charge. >> we were permitted to come to the police station and see anissa. i remember her saying she was very, very scared. that day plays out almost every night in my nightmares. >> and morgan has never hurt a

fly. it was just unthinkable that morgan would do anything to hurt someone else. >> it wasn't until the following day that we knew that she would be charged as an adult. >> the current situation in wisconsin is there are certain categories of offenses that if they're committed by an individual over the age of 10 that that individual has to be prosecuted in adult court. >> reporter: these 12-year-old girls could face decades behind bars. questions about whether or not you know they'll ever be free. >> this law about juveniles being treated like adults for certain crimes was part of a get tough on crime initiative. and the goal was to say even if you're young, if you commit a horrible heinous crime, you're going to be treated as an adult. the flip side of that is when

you see a 10 or 11 or 12-year-old charged as an adult it suddenly makes you say, "wait a sec. does this make sense?" >> it's unthinkable to try a 12-year old child as an adult regardless of what they've done. i mean, she was 12. >> it was weird. i felt no remorse. i thought i would. >> it was weird that you didn't feel remorse? >> mm-hmm. i actually felt nothing. >> there's something that's not right with a 12-year-old that's saying the things that she is. but i think she genuinely understood what she did was wrong. >> but how about stabbing your friend? you think that's right or wrong? >> probably wrong. if it were right, i wouldn't be here. >> how should they be punished for this when they're 12 years old? do they know right from wrong? >> you can certainly know what is right from wrong but still have a problem controlling your behavior. you feel compelled. >> there's a chance that these two girls did something just simply because they wanted to do it. they wanted to experience it.

>> i've wanted to hurt people before, but they're not nice to me. so they deserve it. >> reporter: police now have to dig into their childhoods to see if there were warning signs missed. >> in her drawers, in the closet, there were numerous items that were disturbing in nature. >> they found all kinds of strange things going in there. >> reporter: how typical is it for a 12-year-old to write "i want to die"? >> you would think that a parent would notice that something was going on. >> people wanted to blame the parents for somehow creating monsters. >> you could be looking at a sociopath. definitely.

♪ state of wisconsin versus morgan geyser. state of wisconsin versus anissa weier. >> because they charged them with attempted first-degree intentional homicide, that made the case automatically start in adult court. that also led to the judge releasing their pictures. >> seeing anissa in the courtroom in the jumpsuit with the shackles and the handcuffs and the belly chain really hit hard. it broke my heart. >> that's what i think gripped the public's attention, was how extreme that looked, to see children shackled.

>> that really started the whole split, i think, of public opinion on the case. between those who saw it as these are dangerous actors out in the community that need to be locked up forever and those who thought like something's really wrong with these children, they needed help and should be in juvenile court. >> reporter: detectives now have this information that came from the girls themselves about this plot. >> the bad part of me wanted her to die. but the good part of me wanted her to live. >> reporter: but obviously, police now have to dig into their childhoods to see if there were warning signs missed. and they come upon some startling evidence. >> the middle school called me and said, we want to go through these girls' lockers. there was one picture found in anissa's locker. everything else was found in morgan's locker. so she had tons of notebooks that had all kinds of writings and drawings related to

slender man. >> slender man was originally created as a fiction, as sort of fan fiction and an extension of the campfire horror story. these images that were unclear whether they were nurturing or threatening. >> one of the first things we did is we talked to morgan's parents, told the parents don't go in the bedrooms. keep the door closed. we're going to come over there, and i'm going to have my investigator process that scene. >> when i first entered morgan's bedroom, it just looked like a normal room for a girl of her age. but in her drawers and in the closet there were numerous items that were disturbing in nature. >> they found all kinds of strange things going on there. strange drawings, dolls that had been mutilated.

>> some of the dolls had their hands cut off, arms cut off, legs cut off. >> they found a lot of things that most people would say, "jeez, that should've been a red flag to a parent." and yet no indication that a parent ever said, "hey, wait a minute, what are you doing here? maybe we should get you some help." >> i spoke with the mom and dad and they had no idea what was in her room. >> we started to look at some of the e-mails. we also looked at the computer that morgan had in her house, the ipad that anissa had. >> whenever i'm really bored, i go on my ipad and i look -- go to the creepypasta wiki. >> i had no idea that besides the school-issued email address that she had on her own made a hotmail address and falsified her age. >> a week before this happened,

morgan sent anissa an email that said make sure to clean out your browser history. >> one of the things that shows whether you know right from wrong is saying clear your internet history because we don't want anybody to know that we've been searching for these things. >> in looking through the geyser home computer, there was literally thousands of internet searches that were done -- "how to get away with murder." "what kind of insane am i?" she was searching these things ahead of time. >> the school had turned over to me a list of books that anissa and morgan had checked out of the school library. morgan had checked out books on crime scene investigations, the prison system, mental health conditions. i look at it as, "boy, how do i act after this happens? what role do i play?" >> i definitely had a clear

sense of who was the ringleader, who was driving this between the two girls. it was definitely morgan. during anissa's interview, she was being truthful and hont. i could tell because she would say that morgan did a, b and c. but then she would take responsibility for some things herself. >> you think morgan's completely to blame for it? >> no. i don't think any of this would've happened if i hadn't told her about creepypasta. >> whereas morgan was just putting it all on anissa. >> anissa told me we had to. >> she knew tactics that police use. she knew the criminal justice system. she'd done research on past cases. you can't get more intentional than that. you're preparing, you're planning, you're thinking about this. >> if she wasn't 12 years old, i would think she was some type of sociopath or a seasoned criminal. >> i was hired by the defense to evaluate morgan. i don't think she was deviously planning. i think she was feeling

controlled by slender man. what she would tell me is that she really had no choice but to listen to slender man. >> was it hard for you to wrap your head around what had been done to you? >> no. which i guess says a lot about our friendship. i kind of wasn't really too shocked about it. after i heard why she did it, i was like, well, this doesn't surprise me at all. because she believed so hard in this thing that she would do anything for it. >> i was angry for a long time, especially with morgan's parents. i thought that they were maybe just in denial. >> i don't think i'm insane. >> were you surprised? >> no. i wasn't surprised simply because there is a family history. >> her father? >> yes, her father has schizophrenia.

>> there are moments where my heart is so full of sadness. that's when i put on a mask. i don't allow myself to break down in front of her and see how much this is -- this is hurting me. >> the first time i went to visit her she looked at me and she had sort of this flat expression on her face. and she said, "why are you here?" >> reporter: what did you think in that moment? >> it's heartbreaking. >> reporter: one of the things we knew people would want to know at home, were there warning signs? did these parents look back at the childhoods of their daughters and see something now that perhaps they missed along the way? angie told me the story about showing her daughter, morgan, "bambi." >> bambi, come here. >> we had been concerned to show

morgan the movie. we were afraid when bambi's mother died she would be devastated, that she'd be very upset. >> faster, bambi! don't look back! >> she, in fact, had quite the opposite reaction. after bambi's mother was shot morgan just said, "run, bambi, run," and had no reaction whatsoever to the mother dying. >> reporter: she wasn't at all concerned about the mom? >> no. no, not at all. >> reporter: did you know anything about morgan's fascination with slender man? >> we did. we did. >> reporter: you talked about it with her? >> we did. and she would show us some of the pictures, and she would read us some of the stories. >> reporter: do you remember when she first started talking about slender man? >> that was in sixth grade. it was early sixth grade, when she had met anissa. >> i thought it was really weird and odd. i was never into it. i just kind of went along with it because she was my best friend. >> we had no idea that she believed slender man was real.

>> reporter: did you ever think that this is a little too dark for my daughter? >> when i was morgan's age, i was reading stephen king novels. i remember being 11 years old and riding home from the library on my bike with "it" under my arm. and that's a very scary and dark story. so i just thought it was normal. >> reporter: as this is playing out, this whole legal process, they're holding a competency hearing for morgan geyser. and during that hearing, it's suddenly revealed that she's been diagnosed with early onset schizophrenia. >> i'm not a doctor, but all the doctors agreed that schizophrenia in a 12-year-old is extremely uncommon. it develops later in life. >> reporter: were you surprised? >> no. i wasn't surprised simply because there is a family history of schizophrenia. >> reporter: her father? >> yes, her father has schizophrenia.

>> hbo came out with a documentary called "beware the slender man," where morgan's father talked about his own schizophrenia. >> like you -- you can like see it and like you know it's not real but it totally doesn't matter because you're still terrified of it. like i know there's like -- i know the devil's not in the back seat, but the devil is in the back seat. you know? >> morgan's behavior was directed by her psychotic symptoms. morgan was being guided by voices that were ordering her to kill someone. >> reporter: when you look back, are there moments when you can see her suffering from that? >> it's difficult to say. she was always kind of a quirky kid, but not pathologically so. >> i expected to either get put

in prison or in an insane asylum. i didn't know which to expect. i don't think i'm insane, though. >> reporter: do you feel responsible? >> i think on some level i'll always feel responsible for not knowing that my daughter wasn't well. your job as a mother is to protect your children and to keep them safe, and of course i felt as though i had failed. >> even then, i think there were people who thought, "well, they should've known. they should've had her in treatment earlier. why didn't they see that she was schizophrenic?" >> at 12 it's very hard to identify psychosis. i don't think it would have been obvious to anyone unless morgan told them the symptoms she was experiencing. >> for the first 18 or 19 months after her arrest, she was not treated and she remained in a very acutely psychotic state.

>> these fictional characters. voldemort from the harry potter books, spock from "star trek," slender man, she considered these people to be her friends. she had conversations with them, and she was concerned that if she took medications that would make them go away she wouldn't have anybody to talk to. >> reporter: what would you say to them if they were watching? the other parents? >> i was angry for a long time, that they -- especially morgan's parents, knowing that morgan's dad had schizophrenia. and for a long time i thought that they were maybe just in denial and ignoring her symptoms. but i recognize that they're going through their own hell. >> their lawyers are trying to get their case moved out of adult court and into the juvenile system. >> it's now summer of 2015. judge bohren makes a ruling. >> a major ruling tonight from wisconsin. a judge deciding that the two 13-year-old girls will now be tried as adults. >> i'll order that the defendants, ms. geyser and ms. weier, be retained in the

adult jurisdiction. >> each of the girls has pleaded not guilty by reason of mental defect or disease. >> reporter: no question in your mind where they needed to be? >> adult crime is adult court. if they had stolen a candy bar, sure, that's a child. but you tried to kill somebody. >> so it seems the cases are going to trial. >> there's immense risk going to trial because a jury could conclude that she is not only guilty, but legally responsible. >> we truly believe that anissa knew what she was doing was wrong. >> reporter: this huge question looms over all of this. will these girls be locked up for decades? what will the court decide?

nearly three years have passed since the so-called slender man stabbing attack on a waukesha sixth grader by her two classmates. >> in 2017 the first of these cases goes to trial. it's anissa's case. >> the courthouse had areas roped off for the media. there were so many people there we had to have security push the reporters away from us. >> by the time she shows up, she looks completely different. she looks grown up as opposed to just a few years earlier when we have the mugshot of her at 12 years old, and she seems to get it. we're all looking forward to the coverage. >> and then we hear that anissa has pled guilty and cut a deal. >> that means you participated in the events. >> i understand. >> once she enters into this plea, there's then a separate trial in effect to determine

what should be the punishment. >> they would go to trial simply on whether she suffered from a mental disease or defect and should not be held criminally responsible. so the jury now has to decide, should she have to go to prison or should she simply go to a mental institution? >> we're on the record in the state versus weier. >> it's basically both sides going for broke. >> on the day this happened she did it because she wanted something out of it. she wanted to be morgan's friend. >> on the other side of the court they saw it just the opposite. >> the evidence will show that at the time this occurred anissa's broken mind caused her to lose touch with reality. >> anissa's lawyers were arguing that she was delusional. >> the bulk of the defense's case was mental health experts. they called three of them to back up the defense's argument that anissa was mentally ill. >> i was hired specifically by

the court to do an evaluation of anissa. >> did you find, diagnose a disorder for anissa? >> yes. i did diagnose her with a disorder. >> anissa was diagnosed with shared psychotic disorder. there's an old french word, folie a deux, which is madness shared by two. >> three different doctors or experts all agreed that, as rare as it is, she happened to meet another 12-year-old who was more ill than she was and kind of got caught up in her own delusions in what they call a shared delusion. >> you have a new girl that comes into school who's desperate for a friend being introduced to a girl who's having some mental health problems. and then they had this shared interest. and you couple that with the fact that they're 12 years old and still retaining some of the magical thinking of childhood. and it's this perfect storm.

>> they believed they had to do it. >> i was really scared, knowing that slender man could easily kill my whole family in three seconds. >> essentially, it was protecting their family. they needed to kill somebody to prove themselves to slender man and that their families would be safe. >> prosecutors were saying she knew exactly what she was doing when they stabbed payton. and point to a very specific moment in the interrogation. >> the first line that she tells me in my interview was saying, "the silly thing about this was" -- >> i didn't know i was in danger until after morgan stabbed payton. >> that statement is to me the most powerful statement in the whole case. if she didn't know that slender man had made the threat till after she did it, that couldn't have been what motivated her to stab payton. if that's not what motivated her, what is? is it possible that we have that

extremely rare thing going on here, which is well, we just have an evil 12-year-old? >> the case goes to the jury and they deliberate for 11 hours. >> it took quite a while. i think that the final verdict didn't come until like 10:30 or 11:00 p.m. >> reporter: the time had come. anissa weir, sitting in that courtroom, shaking. >> has the jury reached a verdict? >> yes, we have, your honor. >> reporter: she's about to hear what the punishment will be and where she'll be sent. >> anissa weier was found not guilty by reason of mental disease or defect. >> in the end, the jury decides she should be committed to a state mental institution rather than going to prison. >> with that, i will order that she be committed to the department of health services. >> a late-night verdict in the slender man trial. the decision, not to send anissa weier to prison. >> their decision was humane. and the actions of a 12-year-old didn't deserve the harshest punishment. >> age was everything.

if you're an adult, when you say you didn't understand right from wrong, that's an argument that almost never succeeds. but when you were 12 at the time it happened, you've got a much stronger argument. >> reporter: but it's up to the judge now. the judge will decide how long she'll be sent away. >> we argued strongly for 25 years. >> miss weier, do you want to say anything? >> i know that nothing i say is going to make this right, your honor. and nothing i say is going to fix what i broke. i'm never going to let this happen again. i'm sorry. >> ultimately, judge bohren committed anissa for the maximum period of time. >> with that, then, i commit anissa weier for a period of 25 years. >> after spending 25 years in a mental institution, my fear is that she will not really know how to interact with normal people at walmart, at the gas

station, at pick 'n save. >> all of the focus now shifts to morgan geyser. and morgan is the one who actually stabbed payton. >> i'm sorry. i never meant this to happen. mornings were made for better things than rheumatoid arthritis or psoriatic arthritis. when considering another treatment, ask about xeljanz xr, a once-daily pill for adults with moderate to severe

rheumatoid arthritis or active psoriatic arthritis for whom methotrexate did not work well enough. it can reduce pain, swelling, and significantly improve physical function. xeljanz can lower your ability to fight infections like tb; don't start xeljanz if you have an infection. taking a higher than recommended dose of xeljanz for ra can increase risk of death. serious, sometimes fatal infections, cancers including lymphoma, and blood clots have happened. as have tears in the stomach or intestines, serious allergic reactions, and changes in lab results. tell your doctor if you've been somewhere fungal infections are common, or if you've had tb, hepatitis b or c, or are prone to infections. don't let another morning go by without asking your doctor about xeljanz xr. ♪

anissa weier will be heading

to a mental hospital rather than prison. >> reporter: so now you have one of these girls, anissa weier, found not guilty by reason of mental disease or defect. and all of the focus now shifts to morgan geyser. >> it becomes clear to prosecutors that they're not going to be able to convince the jury to send morgan, who is even more mentally ill, to a prison. morgan's lawyers end up cutting a deal with prosecutors. >> i'll be blunt. one of the reasons we did that is, clearly, morgan was much more psychologically damaged. >> what did you make of what you heard? >> i remember feeling sad at morgan's sentencing hearing because she was not the girl i remembered. so that was sad for me. >> ms. geyser, would you like to say anything? >> i just want to let bella and her family know i'm sorry.

i never meant this to happen. >> reporter: what would you want to say to them? >> i'm so sorry for what payton went through and for what they must have gone through, and i would take it back if i could. >> reporter: do you accept their apologies? >> i don't think i'm there yet. we're still healing, and we're still trying to rebuild our lives. so it's still a little hard. >> the length of the commitment i believe is appropriate at 40 years, and that'll be the order of the court. >> reporter: 15-year-old morgan geyser sentenced in wisconsin today to 40 years in a mental institution. >> if morgan had never met anissa, i think morgan probably would have acted out in some other way. would it have been as violent? i don't know. but morgan was ready to do something, and she found anissa. >> to put it all on morgan or say she led this i think underestimates the power of schizophrenia.

it underestimates the power of the internet to influence people to behave in ways they wouldn't behave in real life. >> i really think it was them working as a team. >> reporter: you're convinced that it was a toxic combination? >> yes. >> reporter: that one fed into the other? >> mm-hmm. >> reporter: for payton leutner it was months recovering from the physical wounds. but the lingering question was how long would it take for her to recover emotionally? how frightened were you still? >> i slept in my mom's bed for a while. just because i didn't want to be alone. i still sleep with like a broken pair of scissors underneath the pillow next to me just in case. >> reporter: to this day. >> it just makes me feel safer. >> reporter: do you think that'll ever go away? >> i hope so. but for now i don't think so. >> reporter: did you ever think you would get her to where she is today?

>> she had so much determination to not be defined by this event and not be the girl who was stabbed that i really think that it's her determination to live a different kind of life. that's what's gotten us here. >> i've come to accept all of the scars that i have. >> reporter: when you see them, do you see a survivor? >> i just see myself. >> what she has taught me is strength and will, just the sheer will to get through anything. >> reporter: there are so many moving, full circle moments to this story of payton leutner. after payton had gone back to school, the man who would be made school resource officer would be dan klein. >> up there is the school she goes to. >> and i thought that's really cool, i was the first officer on scene to see her and now i'm going to have the opportunity to protect her. >> reporter: he has said that he feels in a way sort of lucky that he's still able to watch over you. >> yeah, i really like officer dan.

he's a great person. >> it didn't work this time, obviously, and we're never gonna try again because i hope i never have to see anissa again. >> morgan geyser, anissa weier. they're both 17 now. they're both being held at the winnebago mental health institute. and this was the picture that morgan's mother posted of her not so long ago on facebook. it's not where you pictured your daughter. >> no. i see on social media my friends and family who have children morgan's age, and they'll post pictures of them driving a car, going to homecoming. you know, it's -- it's hard. >> reporter: one of the things i asked angie. would they still be able to live in waukesha? and she sat across from me and said, "we're going to move."

>> younow, i frequently drive by these places that hold horrible memories. and i just want to get us all away from that. >> every six months under wisconsin law you can petition the court for release from a mental hospital. >> i know at some point we'll start seeing the petitions for release and we'll be back in waukesha county. >> i think morgan could rejoin the community, if not immediately, in the very near future. >> waukesha is not a big city. and so if she was released, you can honestly run into each other at the grocery store or the park. payton is in her senior year of high school. she's going to move on to big, wonderful things. she's going to go off to college. so i think right now, i think it's too soon. >> all rise. >> but that's going to come back to judge bohren again and he can decide, you did this once, i'm not convinced, it takes ten more

years and deny it, and she could go back to the hospital. so that's her uncertain future. >> do you fear for the day that either one of them is back out in the community? >> no. because if they ever come near me they're going right back in, so. >> reporter: so you don't walk around with that? >> no. when they get out, i don't think it's going to change my life at all. >> reporter: if she were released today, do you think she would be a danger to society? >> no. morgan's untreated mental illness is what made her a danger. and she is no longer a danger. >> reporter: you talked about morgan's mother. >> mm-hmm. >> reporter: and you have thought about her? >> yeah. i've thought about what she's going through and how hard it must be for her, because i'm sure a lot of people are saying that it was her fault, she raised her wrong. and like it wasn't her fault. morgan's schizophrenic. >> reporter: she's written a letter? >> she did write a letter to payton, yes. >> reporter: would you read it to us?

>> "dear bella, i wish i had words that could make everything better, but i don't. so all i can say is how sorry i am. and i can promise you not a day will go by that i don't regret what i did. >> "stay strong. morgan." >> i mean, it's a nice gesture. and i appreciate it. but they're just words on a piece of paper. >> reporter: if she saw this interview, what would you want to say to her? >> ooh, there's a lot that i wo well i didn't choose metastatic breast cancer. not the exact type.

not this specific mutation. but i did pick hope... ...and also clarity... ...by knowing i have a treatment that goes right at it. discover piqray, the first and only treatment that specifically targets pik3ca mutations in hr+, her2- mbc, which are common and linked to cancer growth. piqray is taken with fulvestrant after progression on hormone therapy and has been proven to help people with a pik3ca mutation live longer without disease progression. do not take piqray if you've had a severe allergic reaction to it or to any of its ingredients. piqray can cause serious side effects including severe allergic and skin reactions, high blood sugar levels and diarrhea that are common and can be severe, and lung problems known as pneumonitis. tell your doctor right away if you have symptoms of severe allergic reactions or high blood sugar while taking piqray. your doctor will monitor your blood sugar before you start and during treatment and may monitor more often if you have a history of type 2 diabetes. before starting, tell your doctor if you have a history of diabetes, skin reactions...

i'm happy. i have good friends that i trust pretty much. >> but i imagine that the trust part is the hardest part? >> yeah. i would say that trust is a big, big thing for me. >> but you've worked on that? >> i'm trying, yh. >> what do you make of your sister's survivor's story? >> i think it really brings a lot of people hope. people knowing that even when you're down so far under and you think there's no way you can get out of something, there's always a way that you can survive. >> when you go through something

like this, it's really, really challenging on families, on marriages. >> reporter: stacie and joe, their marriage didn't survive this. and this is a sign of the true cost of tragedy. >> i know that the two of you have been tested. what does just being here together for your children, what kind of message do you hope that that sends? >> a sense of unity for the kids, for the family. >> we will always do what we need to do for them, and we'll do it together because they are the most important thing to us. >> have you all taken any time for yourselves to give yourself credit for how far the family has come since this happened? >> yeah, i don't want to credit for it because truly it was stacie that did everything, and i'm truly thankful for that. >> there'll be people talking about this forever. there was just an endless fascination. >> we can't change what's on the internet, but we can change

whether our kids access it and if they do access it how they process it. >> i think that the whole dangers of the internet thing, that's probably the simplest thing people will remember. but i think what we found out from the case was, if morgan weren't schizophrenic, probably this doesn't happen. >> reporter: one of the things i will never forget from this interview with payton leutner all these years later is what she said to me when i asked, "what would you say to morgan geyser if you saw her today?" >> if she saw this interview, what would you want to say to her? >> ooh, there's a lot that i would want to say to her. i would probably initially thank her, i would say. because of what she did, i have the life i have now. which i really, really like it. >> you do know that when people hear you say "i would probably

thank her" that they're going on surprised. >> yeah, i'm surprised to hear myself say that. >> why? >> because i wouldn't think that someone who went through what i did would ever say that. but that's truly how i feel. like without the whole situation, i wouldn't be who i am. >> stronger? >> mm-hmm. what happened to me has made me who i am. and i love it. >> payton is such a brave young woman. and david, i know you've spent time with her over the past five years before she eventually decided to talk. >> yeah, and you know her mother and father and brother deserve so much credit here because they have been by her side from the

very beginning on this. but they're the first to tell you, and this is what they told me, that this is all payton and her strength that has carried them through. so payton, thank you for talking with us tonight. and amy, i know that you know we have a note about a member of our own family here tonight. our beloved colleague lauren brennan, who lost her bat well ovarian cancer this week. she'd been with abc news for 16 years. she worked so tirelessly to get us on the air every week here, always with a smile, a laugh, always with her incredible warmth. you know, we celebrated the birth of her miracle twins not so long ago, and tonight we share our grief and our love with her husband jerry and those children and everyone who loved her, including her family, right here. good night.
