A 30-year-old Colorado man who traveled to New London to have sex with a 13-year-old girl he had met online has been sentenced by federal and state courts to a total of 13 years in prison and 15 years of supervised release.

Nathaniel Smith, of Aurora, was arrested by New London police on Jan. 25, 2016, after state police alerted them that a 13-year-old reporting missing from an area town had been located at the Holiday Inn with Smith. Smith had traveled to Connecticut to visit the teen. He engaged in sexual activity with her and planned to take her back to Colorado, according to court documents and testimony.

Smith and the girl had been corresponding through internet-based messaging and chatting services, including KIK and Skype, according to authorities. He was prosecuted in federal and state courts.

On Friday, U.S. District Judge Michael P. Shea sentenced him in Hartford to 156 months in prison followed by 15 years of supervised release. He had pleaded guilty in December to enticing a minor to engage in sexual activity. 

On Monday, New London Superior Court Judge Hillary B. Strackbein sentenced Smith to 11 years in prison, to be served concurrent to the federal sentence, for risk of injury to a minor and violation of a protective order. Strackbein sentenced Smith "in absentia," or without him being present, since he remains in federal custody.

This matter was investigated by the Federal Bureau of Investigation, New London Police Department and Connecticut State Police. The case was prosecuted by Assistant U.S. Attorney Nancy V. Gifford and Senior Assistant State's Attorney Theresa Anne Ferryman. He was represented by attorney Kelly M. Barrett from the federal public defender's office and attorney M. Fred DeCaprio from the public defender's office in New London Superior Court.
