{Lexington, Kentucky}...Marco Antonio Flores-Benitez, 38, and Roxana Serna-Olea, 36, two people arrested last fall, along with others who were part of a large prostitution ring pleaded guilty Friday in federal court in Lexington. Flores-Benitez, identified in court documents as "somewhat of a leader" in the organization, pleaded guilty to one count of conspiracy to commit sex trafficking by force, fraud or coercion. Serna-Olea pleaded guilty to one count of inducing or persuading a person to travel in interstate commerce to engage in prostitution. Authorities say Spanish-speaking women from states including North Carolina, South Carolina, Tennessee, Alabama, Michigan, Illinois, Indiana, Ohio and Maryland were recruited or forced to come to Kentucky to work in prostitution. Assistant U.S. Attorney David Marye said at Friday's court hearing that Flores-Benitez and Serna-Olea operated a prostitution-delivery service for customers in Fayette, Woodford, Oldham and Jefferson counties, beginning in December 2006. They also operated a brothel on Cross Keys Road in Lexington. Flores-Benitez lived on Delaware Avenue in Lexington, where some of the prostitutes also stayed,
