A Kansas doctor awaiting trial has filed a complaint with Butler County jailers about conditions he has faced while in custody.

Doctor Stephen Schneider told his family in a letter that his phone privileges were taken away and that he was sent to isolation for no reason. Both of these events happened moments after Linda Schneider agreed to do an interview with KAKE News over the phone last week.

Schneider and his wife face a 34-count federal indictment on conspiracy and other charges. They are accused of being responsible for at least four drug-overdose deaths of patients.

Schneider's relatives received his letter this weekend. They think the Haysville physician and his wife are being railroaded by federal prosecutors.

U.S. Marshals spokesman Logan Kline says the Schneiders are being treated the same as others in federal custody.
