A North Carolina man was sentenced Thursday to 30 years in prison for coercion and enticement of a minor.

Adam Cain, 41, of Roanoke Rapids, North Carolina, also was sentenced to 30 years’ supervised release following his sentence, according to a press release from the U.S. Attorney’s Office for the Eastern District of Virginia.

Cain pleaded guilty to the charge on Dec. 10, 2015. According to court documents, in August 2015, a concerned relative of a 15-year-old girl contacted the police in Windsor, Va., because she found sexually explicit conversations on a computer tablet between the girl and Cain, according to the press release.

Cain was a registered sex offender.

The investigation revealed that Cain and the girl had been speaking online for some months, according to a press release from the U.S. Attorney’s Office.

At one point, prosecutors said, Cain drove to Windsor, picked up the girl, and then drove back to his residence in North Carolina. There, they engaged in sexually explicit conduct. Cain also took sexually explicit pictures with his phone of the girl.

U.S. District Judge Arenda L. Wright Allen handed down the sentence.
