joining us. one dna test, taking an unexpected turn. the true identity of her father, a secret hidden for 33 years. the shocking twist to one family's search for the truth. here's kyra phillips. >> my name's eve wiley. i live in dallas, texas, and when i tell people my story, their sdwrjaws hit the floor. >> reporter: it's a story not even we could believe at first. full of twists and turns, raw emotion. >> this sucks. >> reporter: a secret reveal that would leave eve wiley wondering who am i and where did i come from?eels just going to jump out of my chest. five, four, three, two, one. >> reporter: eve's story began 33 years ago in center, texas, a happy, full-of-life little girl. who always knew there was

something just a little different about her. dad doug passed away when eve was just 7. and at 16, while snooping through her mom's e-mails, eve uncovered a bombshell. >> i saw all of these e-mails about artificial insemination and after about the 10th or 11th one i clicked on it. and when i clikd cked on that oi scrolled down. and it said i'm gathering information for my daughter, she was born in 1987. and it was my birthday. >> reporter: what was your reaction? >> what the [ bleep ]? i wasn't angry. it was one of those things where everything kind of made sense at that point. my sister and i look absolutely nothing alike. i'd been married for about a year, and had not had any success, so i decided that i'd

seek out medical attention, help. the doctor was very well-known in the area. he is an obgyn, and he does work in fertility issues. >> he was that doctor in the community that everybody respected and really thought very highly of him and absolutely trusted him. >> reporter: after some failed attempts at artificial insemination, margo chose an anonymous donor, she knew him as donor 106. >> he was interested in politics and film. and that's so alien to me, i thought, he's the one. >> reporter: so at what point did you decide i want to find him? >> immediately. >> reporter: and when eve turned 18 she sought out donor 106 and found him. >> the first phone call was tracking me down to make sure i was steve shull to make sure i was the donor. two weeks later they reach out and say one of your genetic

offspring wants to reach out to you. >> reporter: a self-proclaimed hippy, steve had traveled the world before settling in california. just skrachicraping by, he found by a local sperm bank. he and eve set up ag >>tt kindf natural. >> it felt like we truly genetically connected. there was no doubt in my mind that daughter. >> reporter: it was perfect. the families blended, and eve was on top of the world. >> the poster child for the ultimate donor-conceived success story. >> briefly. >> until we found out otherwise. >> reporter: wanting to know more about her new family history, eve turned to commercial dna testing. >> my name is megan, and i met my birth mom for the first time today. >> then i started thinking, hey, i could do this and maybe find

some siblings. i got the kit, spit in the tube and sent it off and waited. >> reporter: the problem was, cko geographic areas d 106, had connections. >> she came to me and said, mother, there's something wrong with the things i'm seeing. these people that are popping up in my dna. >> reporter: and when eve got on the phone with one newly-discovered relative, everything changed. he told her he had an uncle, dr. kim mcmoreys. she remembered the name. it was her mom's fertility doctor. so at what point did you sit back and say oh, my god, my biological father is my mom's fertility doctor? >> honestly, it was the moment that that first cousin said his name. it just made sense at that point. >> i was just in shock. i couldn't believe it.

i really trusted him. >> reporter: rocked by the revelation about her conception, eve demands to know why, writing to dr. mcmoreys for answers. >> through genetic testing i recently learned that i am not biologically related to donor 106. through publicly available testing data i a am biologyki related to certain relatives of yours. okay, looks like nothing today. >> reporter: but finally. >> feel like my heart is, whoa, going to jump out of my chest. okay. five, four, three, two, one. i have certified letter for you today. >> okay. there it is. all right, great, james, thank you so much. >> all right. >> dear mrs. wiley, i have

searched through our medical records. >> trying to find some answers to your questions. >> reporter: the doctor writes that when eve's mom was going through treatments they weren't having success. in fact he says donor 106's sperm failed. he discussed adding a local sperm donor to the mix. >> i told him i didn't want a local donor. >> we talked about the problem that number 106 wasn't working. i told her about the option of using number 106 as primary but augmenting it with another sample. i thought she understood this. >> reporter: margo insists that conversation never took place. >> absolutely not. that just didn't happen. >> reporter: but one thing dr. mcmors aever mgo that the heor106 was hthsale cnld mic soo

days. >> my characteristics were closest to the characteristics of 106. >> reporter: this leading expert told us this is highly unethical, today or 33 years ago. >> if the doctor wanted to be the genetic parent of a patient's offspring, he would have to engage in a very deep and thorough conversation in which the patient gave informed consent. >> reporter: dr. mcmoreys declined our request for an interview, but through his attorney told us he had a good reason for not telling margo he was using his own sperm. reason for not telling margo he was using his own sperm. he says donor respte tgise possibly

can. today eve is determined to write the final chapter of her story. she lobbying to make it a felony for any doctor to use any donor's sperm without the express consent. >> we found out that this was not a crime. this man was my mother's doctor. he was not her donor. >> sorry about your experience, but through your testimony in the future we'll be able to hold people accountable. >> reporter: she still considers steve her dad, and she also knows her story may have more twists to come. do you sit back beautiful life? i've got an amazing husband, i have two amazing kids. >> i do, and i'm happy i'm

alive, but it doesn't make it right. it doesn't make it okay. my pain is still my pain. >> reporter: for "nightline," kyra phillips in dallas, texas. next, one family's struggle to unplug from a technology-driven world. standard of care. it's the idea that if our mothers were diagnosed with cancer, how would we want them to be treated? that's exactly how we care for you. with answers and actions. to hear your concerns, quiet your fears, lift your spirits. that's the mother standard of care. this is how we inspire hope. this is how we heal. cancer treatment centers of america. appointments available now. cancer treatment centers of america. is your floor's best friend. only roomba uses 2 multi-surface rubber brushes to grab and remove pet hair. and the roomba filter captures 99% of dog and cat allergens. if it's not from irobot, it's not a roomba.

questions we're all asking. are we spending so much time on our screens it's undermining our families? our children? our relationships? even changing our brains? let's start with this fact. 49 days every year, that's how much time adults spend looking down just at our mobile screens, and that's a month and a half each year of our lives. parents across the country tell us they feel they're in a crisis with their kids. >> when the time comes to tell them to stop my daughter, she's 3, all she does is swipe, swipe, swipe. >> we need help. parents need help. >> reporter: and kids have something they want to say to grown-ups. >> how do you feel when mom and dad are on their cell phones? >> irritated. >> reporter: so a few months ago we sent out a message, asking all of you to tell us what you're feeling about this new world, and is there a struggle inside your home? one of the messages that came

back to us was this one from a family asking for help. so we head to the midwest and arrive at the house where this family has agreed to let us install six cameras and software to keep track of their time on devices over the course of about 30 hours on a weekend. and here they are, that family who agreed to open their lives, to do something brave in case it can help your life to. she's an executive at a large global manufacturer. dad, a financial adviser. they have four children. one at college, three at home. so we're rolling on friday as school is over. the youngest child, 12 year old johnny puts on his headphones and gets ready to spend the rest of the afternoon locked into the video game fortnight. he tells our camera he agrees with his mom he wants to spend more family time. >> our family needs help. we really don't know what we're doing. sometimes it gets, like,

>> ah. >> reporter: michelle says over the years she tried to set limits, but it always rolled back, and she's pretty much given up. oth oth our cameras keep rolling on saturday. and later when we scroll through the hours of tape we see what it's like when the family makes a trip to the middle school basketball game other plays card for about an hour. or the loving kids have such a good time, which makes it striking when we also see scenes like this. eyes fixed on-screen for hour after hour. ve except a scrolling finger and their little dog. so we asked the family to gather with us around the take for a kind ofey dinny. duri t day and a half we were there, he was nearly 12 hours on screens, seven of them video games. carson even longer, 14 hours. >> we need an intervention.

>> johnny's on his device now. >> reporter: and kristin's stunned to learn she's been on 12 hours. the parents, five hours each of social media, facebook, twitter, youtube. so we asked the renowned gutman institute, which has been helping families for more than 20 years to watch the tapes too and give this family some steps, some guidance toward the change they told us they wanted. a husband and wife, they have counseled families for 25 years. >> how do we embrace it as a thing that enhances our families rather than takes away from them. >> reporter: two of the kids wander in to say hello and get a teaching moment about family conversations and asking something other than the usual . , would i fifferent if you said, what's best thing that happened to you >> it'd get my mind thinking back on the day. >> that's a good idea. >> reporter: so now the family is ready for step one. have a family meeting.
