WICHITA, Kan. (AP) — A U.S. Supreme Court decision last year has breathed new life into the case of a former Kansas doctor and his wife convicted for a moneymaking conspiracy at a pain clinic linked to 68 overdose deaths.

Stephen Schneider and his wife, Linda, were convicted in 2010 of conspiracy to commit health care fraud resulting in those deaths, unlawfully prescribing drugs, health care fraud and money laundering. Schneider was sentenced to 30 years and his wife 33 years.

Their attorneys are seeking a new trial or sentencing after the high court ruled in a separate case that the victim’s drug use had to be the actual cause of death, not merely a contributing factor.

A Kansas federal judge is considering a string of filings on the issue that culminated on Thursday.
