Following the erroneous testimony of a celebrated expert witness, a mentally disturbed mother was convicted of murdering her five children. The witness’s evidence was the foundation for an inference that the defendant had concocted an insanity defence based upon a popular television drama series episode. In fact the expert had “falsely remembered” a non-existent episode of the series. The conviction was reversed upon appeal on the sole ground of the witness’s erroneous testimony. Upon re-trial, the defendant was found not guilty by reason of insanity.
