Three others charged in the case, women who allegedly worked as prostitutes for the organization, made deals with prosecutors and pleaded guilty to amended charges.
Christina Mae Byler, 35, pleaded guilty last month to conspiracy to conceal criminal proceeds and will be sentenced in May.
Julianne Renee Rupert, 31, and Elizabeth Elaine Andrade, 30, pleaded guilty during the summer to conspiracy to conceal criminal proceeds and received deferred prison sentences, court records show.
Another co-defendant, Mario Shavez Diaz, 30, is charged with one count of racketeering. His case is pending.
Prosecutors contend Diaz worked as a pimp for Coulter.
At a preliminary hearing for Diaz last month, a former prostitute testified he introduced her to the business. The woman said Diaz beat her, kept her earnings and then tried to extort her when she wanted to quit.
