Stephen Schneider, a physician, and his wife, Linda Schneider, argued in a court filing Tuesday their lawyers were ineffective at their trial.

The Schneiders were convicted in 2010 of conspiracy, unlawfully prescribing drugs, health care fraud and money laundering at what prosecutors called a “pill mill.” Stephen Schneider was sentenced to 30 years and his wife to 33 years.

The 50-page document written by the doctor from federal prison outlines the defense he believes his lawyers should have presented. He contends they failed to use exculpatory evidence and witnesses.

Schneider argues his attorneys failed to show that prescriptions were for legitimate medical reasons and the conduct was within the bounds of professional practice.
