good evening. thank you for joining us. parents saying a teacher sexually abused their son. the app on their phone they used to track her leading to an explosive confrontation. >> what type of [ bleep ] perverted person are you? i want to know right now. >> reporter: an angry father confronting the woman who allegedly sexually abused his 13-year-old son. >> you are a [ bleep ] monster, you are a pedophile. you're a child molester, do you understand me? >> reporter: on the other end of that phone call, britney samora, their son's sixth grade teacher at las rises elementary school. >> why do you say that? >> reporter: not long after she was arrested. >> body cam on him as well -- >> reporter: the 27-year-old pulled over and put in handcuffed. charged with sexual abuse after allegedly carrying on a secret relationship with one of her students. >> did you have an inappropriate relationship with a 13-year-old boy? one of your students?

>> reporter: it wasn't that trove of handwritten notes that would uncover the alleged abuse. instead, the boy's parents discovered illicit cell phone conversations by using a free app called sentry. it monitors key words and one day flagged repeated use of the word "baby." >> i saw at the bottom that it had mrs. zamora instagram profile. i told my husband and we looked it over. >> reporter: dad confronted his son. the child explaining during this interview with investigators which was blurred to protect his identity -- >> he came home and he was all like, who are you chasing? and then he showed me the text. and he like, you have one chance to tell me, don't lie. >> the parents did all the right things. they had an open and honest dialogue with their child. they monitored their child's cell phone usage. they realized that something was very different with their child. and they immediately contacted both the school and the police

department. >> reporter: now a year later the case once again making headlines after the videos and documents went public. this case part of a disturbing reality. the u.s. department of education estimates that 4.5 million students, or 1 in 13, experience sexual misconduct at the hands of a school employee sometime between kindergarten and 12th grade. >> culturally we have this misconception, if someone's a hot teacher and it's a young boy, this is something they want and that it's a positive. that in fact is not the case. studies show a violation of trust, especially when it's a teacher, can be very damaging psychologically. >> a 35-year-old teacher who had sex with a 13-year-old sixth grader sentenced to 80 days in prison -- >> reporter: the teacher/student affair has made headlines before, most famously with mary kayla toreny. 1987, the married teacher pleaded guilty to two counts of rape for sexual abusing her

12-year-old student villa fualaau. they'd go on to marry and have children. in 2004, 23-year-old deborah la fay was busted in florida for having sex with a 14-year-old student. she pleaded guilty to less serious offenses and served no time in jail. like many other convicted teachers, she did have to register as a sex offender. >> one of the most damaging things about these cases of child sex crimes is the power dynamic. the fact that you have this almost parental figure grooming you and abusing you can have lifelong ramifications on the child victim. >> reporter: in the arizona case officials say zamora began illicit communications with the 13-year-old boy, a student in her class, by using a school messaging app. >> she said that like text her so she wouldn't be bored. and i said, hi, mrs. zamora.

she texted back hi and then we started texting. >> reporter: he said the messages kept up and soon turned explicit. >> i don't remember how it got really intense, but we would like flirt. i'd say like -- she'd be like, omg, i love you. i would tell her i love her too. she was talking about how she wanted to do stuff with me and i'd tell her i wanted to do that too. >> reporter: the boy says things escalated to sexual touching during class while other students watched videos. then he says one night while the alleged victim and his siblings were sleeping at their grandparents' house, they met up outside school. >> and she was all like, let me come over so i can show you how much i love you. she was all like, where is your grandparents' house? send me the address, because her husband was fishing. >> reporter: he says he snuck out and met in her vehicle. >> i got in the car and she started kissing me and she gave me a [ bleep ]. and then i left. >> reporter: he says it would happen again the next night, only that time it ended with

intercourse. >> so then you said that she got on top of you. whose idea was that? >> hers. >> hers. what was she saying to you? >> she was just telling me to relax. >> reporter: one occasion another student allegedly acted as a lookout. that child also interviewed by police. >> was ms. zamora saying anything? >> no, they were just doing it. it was very uncomfortable. so that's why the second day they were doing stuff, i just left the room. >> reporter: this friend says the alleged victim confided in him, begging him to keep it secret. >> like they're texting dirty stuff. i got instagram, they text dirty stuff. >> reporter: parental control apps or the rise, a big business projected to reach $9.5 billion by 2023. apps like family time and web watch are tracking mobile activity and blocking racy sites. these parents using one such app to discover those text messages.

they say afterwards they received that surprise call from zamora which they recorded. >> can you explain to me, can we meet to talk about this? we can settle outside. >> oh, yeah. oh, yeah, that's what we can do, so i can give you a chance to do it to some other kid? yeah, exactly that's what we're going to do. no, do me a favor. do not call me back again. do you understand me? make sure you tell your husband what's going on. >> he is right here, can he talk to you? >> reporter: zamora put her husband on the phone to defend her. >> hey, man. >> don't say hayman to me, you've got a [ bleep ] monster. if i was you you stupid [ bleep ] i'd leave her. >> man, listen -- >> listen to me. i am not going to settle outside of court. there's not enough money you can [ bleep ] possibly ask and offer me to settle this. get it. get that through your [ bleep ] head. >> reporter: the next day police cameras recorded the meeting between the boy's parents,

school officials, and law enforcement. >> let's go to school resource officer -- >> reporter: both parents emotional. >> have you done anything with your teacher? did you have sex with your teacher? and he said yes. >> he said yes. okay. >> childhood is [ bleep ] gone. he's 13. >> you tend to think of women as safe and nurturing, especially when they're teachers. abuse is abuse. it does not matter what gender is committing it. >> reporter: zamor wachlt was arrested and charged with eight counts of sexual misconduct with a minor, two counts of child molestation, and one count of transmitting obscene material. she pleaded not guilty. >> go ahead and come on up, face the wall for me, put your hands behind your back -- >> i want you to explain, you know, how this came to happen. >> can i have an attorney? >> you can. is that what you want? okay, all right. >> will i be going home today? >> no.

>> they're going to tear me apart. >> reporter: in a raid on her classroom, investigators say they found dozens of notes from the boy to his teacher. many on brightly colored post-its or scraps of notebook paper. the childish handwriting spelling out messages like, you're so sexy, you just look really cute right now. >> very often the teachers are very popular, very well liked. so they use that as a way to seduce and to appear safer than they actually are. but the studies show that if they were put in the same situation of teaching, they're likely to reoffend. >> i would love to go home. >> reporter: for now britney zamora remains in maricopa county jail. she surrendered her state teaching certificate in december. an attorney for britney zamora did not return our request for comment. we're going to switch gears completely. she went from being a waitress to a viral youtube baroness.
