Two women are scheduled to plead guilty this week to charges that they helped operate a $4 million prostitution ring based in the D.C. area.

Court records show that plea hearings are scheduled for Tuesday for 30-year-old Alafaka Opuiyo and 30-year-old Kiana McKelvin. The two, along with four others, were indicted in January in federal court in Alexandria for allegedly committing money laundering and violence to run a prostitution business disguised as an escort service.
