Robert Courtney, the former Kansas City pharmacist who has admitted to diluting prescriptions given to thousands of patients, faced sentencing on Thursday.
Under a plea agreement, U.S. District Judge Ortri Smith can give Courtney from 17 1/2 to 30 years in prison.
Hundreds of victims and family members are expected at the courthouse. Among them will be Marge Vermillion, whose husband died soon after taking cancer treatments mixed at Courtney's pharmacy.
