Stacey Rutherford believed she had found "a gold mine" when she married Justin Rutherford.But in 2021, the Pennsylvania mother of four made a discovery that would shatter her life. Hidden inside the bathroom of her family home was a secret camera planted by her second husband, a respected local physician. For years, it silently recorded, police said. What began as a shocking violation soon unraveled into something far darker.Justin, 36, pleaded guilty to sexually abusing his stepson and another minor, and was later convicted in a murder-for-hire plot. The disgraced doctor's twisted double life and his familys fight to reclaim their story are now the focus of the ABC News Studios true crime docuseries streaming on Hulu, "Betrayal: Under His Eye."DAUGHTER OF NOTORIOUS KILLER DAN LAFFERTY CHOOSES FORGIVENESS OVER HATRED AFTER DECADES OF SHAME"Theres a lot of shame and guilt," Rutherford told Fox News Digital. "You always think, as a mom, if you know your kids so well, and youre so close to them, how did you not see that something was broken? How did you not hone in on the fact that something wasnt right at home? The feeling gets less and less over time, but its also a feeling that never goes away."After struggling to find love, Rutherford, then a single mother of two, came across the charming medical student on a dating app in 2015. By the time they married in 2019, he was a practicing physician. They went on to welcome two more children."Initially, I really liked him," Rutherfords son, Tyler VanScyoc, told Fox News Digital. "My mom didnt bring too many men in, but I remember when she did introduce us to someone she was seeing, they really didnt speak a word to us. But this was different. He was actually interested in getting to know us. He asked about what we liked, what we wanted to do with our lives. He would throw a football around with us. I thought he was a good guy, a good match for my mom."Rutherford believed she had the perfect home life. But that all changed in the summer of 2021 when a teenage friend of VanScyocs discovered a hidden camera disguised as a phone charger in the family bathroom. The friend immediately informed his mother, who called the police, according to investigators.According to the docuseries, Justin captured thousands of photos of people showering, using the bathroom and changing their clothes.During the investigation, a friend of VanScyocs told police that Justin sexually assaulted him during a sleepover while the friend was under the influence of alcohol, GMA reported. VanScyoc later confessed that his stepfather had been sexually molesting him since he was 11.FOLLOW THE FOX TRUE CRIME TEAM ON X"Initially, I didnt think there was any courage there in my speaking out," VanScyoc explained. "I felt like I had to. And I think the more that I shared what happened to me, the more I was no longer letting it eat me alive."In the docuseries, VanScyoc described the deep shame he felt after coming forward. He recalled that whenever he tried to resist, his stepfathers demeanor would change. His anger surfaced quickly if VanScyoc didnt do exactly what he wanted. But once his friend spoke out, VanScyoc realized he couldnt stay silent any longer."When everything first came out, I didnt really hate him yet or anything," VanScyoc explained. "I didnt really feel many of those feelings. It took a while for it to turn into that. But there was a lot of guilt there."I just thought, Man, I took this whole guys life away. But he did take a lot away from me as well. And I was still connected to him in the aspect that he was my father for all those years. He was still my father. And when he wasnt doing what he did to me, or wasnt in his, I guess you would say, monster mode or whatever, he would act like a good dad. He treated me like any good dad would treat their kid.""He built a connection with me," the 20-year-old continued. "I think thats a lot of what he used against me. He built that connection with me, made me trust him, and made me love him as well. And I did. I loved him, cared about him, trusted him all those things. It was hard to learn that all of that was years and years of manipulation."Rutherford said she never noticed any red flags nothing that made her suspect the man she loved was hiding a dark secret.SIGN UP TO GET THE TRUE CRIME NEWSLETTER"When I was dating, my big fear was that somebody was going to hurt my children, and I wouldve been the one to bring that into their lives," she said. "I didnt introduce them to somebody right away. Knowing that I brought him into their world, knowing that the only reason he was in their world was because of me? Yes, I carried a lot of guilt. As parents, were supposed to be able to protect our kids from anything. And when you cant, it feels like its your fault.""I had no idea what any of this stuff was," the 47-year-old reflected. "I wasnt abused as a child. I didnt know any friends who were abused. That just wasnt something I knew about.I was 30 when I met him. I should have known about those kinds of things, but I didnt. Guilt has been the silent killer."Justin managed to flee to Europe. But when he returned to Dulles International Airport in Virginia, he was arrested. While awaiting trial, he attempted to orchestrate VanScyocs murder through letters to a close family friend, police told GMA."I was completely devastated," said Rutherford, fighting back tears. "I knew he wasnt who I thought he was, but this was something I could never have imagined. It changed all of our lives. It made me realize just how ugly this world is. I dont like to go to a lot of places in public. Sometimes when my kids walk in, I jump. I dont think Ive slept the same since all of this happened. How do I know hes not in there, still trying to take revenge on my son? All it takes is for one person there to believe him, to think hes a doctor with a lot of money.""Im always looking over my shoulder," she admitted.In 2023, Justin was sentenced to 26 years and 10 months to 70 years in prison, the Berks County District Attorney's office announced. He later received an additional concurrent sentence of five to 10 years for attempting to arrange VanScyocs murder from prison, GMA reported.GET REAL-TIME UPDATES DIRECTLY ON THE TRUE CRIME HUB"When I had to go through photos for the documentary, it was very difficult," said Rutherford. "Tyler was always a big snuggler, and he would snuggle on the couch with me. Hed snuggle on the couch with Justin. Looking at the photos now, it makes me sick. When I initially took them, I thought they were very sweet photos of my children being loved by a stepparent."Tyler always had friends over for games or to get in the pool with us. And Justin wasnt throwing himself at the kids. It was like the big brother wanting to play video games, and they didnt want him there. I saw those things as innocent. But Im trying not to take every single memory and twist it. Im trying to let it be what it was for us at the time."Following Justins conviction, the family kept tight-lipped about what happened to them.
