HOLLY SPRINGS, N.C. (WNCN) – A Holly Springs father is asking state lawmakers to do more to protect teenagers after he says his 16-year-old daughter repeatedly met up with an older man she met online, often for sex. John Roger says raising the age of consent could help protect kids like his daughter. He also says parents need to be involved in what their kids are doing online. He only found out Tuesday what his daughter had been involved in, but he says it appears it has been going on for weeks. 23 men accused of coming to Triad to meet minors for sex in sting operation "We never thought this could happen to our daughter or any of our kids, and we were just totally unprepared for this revelation when we found out,” he said. Rogers has always tracked his kids' internet traffic, which means he is able to read messages they send. He says his kids know that, but when he checked his 16-year-old daughter's traffic Tuesday afternoon, he noticed her visiting Chat Roulette, a website where people can chat with strangers. He found messages his daughter exchanged with a man that eventually moved to other social media platforms. He said the messages included graphic sexual messages and images and arrangements to meet for sex. “She was meeting up with him. They were spending time in his minivan,” Rogers said. Rogers explained he had noticed some changes in his daughter’s behavior: she started leaving for the school bus 45 minutes to an hour before she normally did, but he assumed she was meeting a friend. Once he read the messages, he realized she would meet a man, often for sex, before school. He said the same man would also pick her up from school when Rogers assumed she took the bus home. Rogers said he found the man's phone number in his daughter's contacts and looked him up. He says the man appears to be 31 and might have driven down from New Jersey to meet his daughter. Rogers said he instantly feared his daughter was in danger of being trafficked. “There could have even been a possibility that she would never come home again,” he said. Rogers took this to the police, but he says officers told him because the age of consent in North Carolina is 16, there is not much they can do. “I was kind of in shock because I'm like, well, here I am legally on the hook for my kid, but you're telling me I can't do a damn thing about it if they decide they want to have sex?” Rogers said. In Rogers’ daughter’s case, her age did not make these encounters illegal, but the Holly Springs Police Department says police say it is seeing more internet sex crimes against children. "Yes, it's become more of a problem just because every teen has a cell phone nowadays, every teen has, you know, Snapchat, Tik Tok,” said Detective Sgt. Mitchell Ham. Ham is part of the Internet Crimes Against Children Task Force, and he said part of his mission is to educate families. “And what I try to tell teens is don't have a conversation with somebody you don't know,” Ham said. Rogers also wants lawmakers to raise the state's age of consent to 18 to protect teens like his daughter. He told CBS 17 that he reached out to his local state representative and state senator to talk about the possibility of introducing a bill. "I'm just hoping that if one of those kids can be saved from what my daughter went through, you know, and what our family went through… It's all worth it,” he said.
