TOPEKA, Kan. (AP) — A 25-year-old Topeka man has been sentenced to 14 years in federal prison for sex trafficking a 15-year-old girl.

The federal prosecutor’s office in Wichita said Wednesday that Dominique Emanuel Tyson pleaded guilty to one count of sex trafficking a child and was sentenced to 14 years in prison.

Tyson admitted in the plea that he took the 15-year-old girl to a motel to meet a man who saw her photo in an online classified advertising website. The customer was actually working undercover for the Topeka Police Department and FBI.

The Topeka Capital-Journal reports the case began when a community corrections officer called police reporting that the girl had run away from her placement and authorities later found her photo in the online ad for escort services.
