A Kentucky attorney has been sentenced on human trafficking charges after he was implicated in a former judge’s criminal case.

Robert L. Poole, 53, of Florence, was sentenced Friday to eight years in prison, which was probated for five years with conditions, according to a statement from Kentucky Attorney General Daniel Cameron’s office. Poole pleaded guilty in October to five counts of promoting human trafficking for commercial sex activity in Kenton County.

He was indicted in 2018 on 15 charges, including third-degree rape, after a nine-month investigation by the Erlanger Police Department and the attorney general’s office.

The investigation into Poole’s activity began when police found evidence that implicated Poole in the case against former Campbell County District Judge Timothy Nolan. Nolan was sentenced to 20 years in prison for human trafficking in 2018.
