The leader of a prostitution operation run out of three Omaha spas pleaded guilty Friday to racketeering and money laundering.
Under a plea agreement, William R. Knox, 64, of Omaha, admitted he managed the sex-for-hire ring between 1998 and 2012. Under his rule, 20 workers performed various sex acts on customers who had paid a fee for their services. Tips also were welcome, federal prosecutors said.
Knox paid $225,000 as part of a money judgment. He also faces up to 25 years in prison when he is sentenced July 29.
In January, U.S. District Judge Laurie Smith Camp sentenced Knox's partner, Kim Bivens, to 37 months in prison. The Omaha woman was given credit for time served, plus three years of supervised release.
Smith Camp also recommended that Bivens, 46, go through a 500-hour drug and alcohol rehabilitation program.
Bivens and Knox were accused of operating the sex-for-hire ring with Tammy L. Schuck, of Omaha, and Tabatha N. Ashburn of Junction City, Kan.
Also charged was Christopher J. Tierney of Omaha, who is accused of running the spas' online presence and managing electronic records. The cases against Schuck, Ashburn and Tierney are pending.
Knox and the others kept an electronic list of 2,500 clients and their status with the spas. Big tippers were noted on the list and were eligible for more sex acts.
Authorities have not made the client list public.
