WICHITA, Kan. — Dr. Stephen Schneider was sentenced to 30 years in prison Wednesday and his wife, Linda, 33 years for unlawfully prescribing painkillers that resulted in scores of overdose deaths.

Attorneys for the Schneiders had asked a federal judge to sentence them to the minimum 20 years in prison, rather than the life sentences prosecutors had sought.

A jury in June found the Schneiders guilty of unlawfully prescribing drugs, health care fraud and money laundering following a nearly eight-week trial. Jurors convicted them of a moneymaking conspiracy that prosecutors linked to 68 overdose deaths.

In addition to conspiracy, the Schneiders were found guilty on five counts of unlawfully writing prescriptions and 11 counts of health care fraud.

They also faced 17 money laundering counts. Stephen Schneider, 57, was found guilty on two of those counts; Linda Schneider, 52, was found guilty of 15 money laundering charges.
