Lindsay Clancy fixation and alleged plot to poison husband emerge as accused mom claims psychosis

An Illinois mother accused of strangling her 2-year-old son was suffering a "psychotic episode" when the child was killed, her high-profile defense attorney says, even as prosecutors allege she was plotting to poison her husband.

The competing accounts come as Corie A. Walsh's attorneys accuse jail officials of failing to provide her prescribed psychiatric medication after hospital doctors recommended she receive around-the-clock psychiatric care upon her discharge, according to the defense.
