This story is part 4 of the CBS News Texas series The Long Hunt. Click here for part 1, part 2 and part 3. Convicted kidnapper Nicholas Carney is already serving a life sentence, but the investigation into his alleged crimes isn't over. I have no doubt that there's probably more victims out there, said Ashley Keith, who Carney abducted and sexually assaulted when she was 8 years old. Oh, I feel like there's probably hundreds, said Amy Birch, who Carney exposed himself to while working as an ice cream man when she was 6 years old. That's my whole reason, really, for speaking up. The crimes of Nicholas Carney In this series, The Long Hunt, CBS News Texas has retraced Nicholas Carney's crimes across two decades and two states. In 1981, he was driving an ice cream truck in Tulsa, when Birch said he invited her to take a look inside. He had unzipped his pants, Birch said in an interview with CBS News Texas, and asked me if I wanted to touch him. After decades under the radar, he was arrested in December of 2024. Earlier this year, a Collin County jury convicted Carney for Keith's 1991 kidnapping and sexual assault. She was abducted as she walked with a friend less than a block from her home in Plano, Texas. He asked if we'd seen his white dog, Keith said, just to get us to stop long enough, and then the next thing I remembered is he grabbed me. Carney is now awaiting trial for the 1999 kidnapping and sexual assault of a 9-year-old Dallas girl who was taken while walking home with a friend. According to reports at the time, the attacker had gotten their attention by asking if they'd seen kittens in a nearby field. Both Keith and the victim in 1999 were released hours after their abductions. This is a man who knew how to manipulate children by either being an ice cream truck driver or by talking about pets, Keith said. He was doing these things in broad daylight. Plano Police Det. Aaron Benzick, whose investigation of Keith's decades-old kidnapping resulted in Carney's life sentence, said his work is not over. This is a pattern.
