Yes, their crimes are horrifically linked: Andrea Yates and Lindsay Clancy both claim they were “commanded” to kill their children one by one, both were former nurses, both were raised Catholic and both pleaded guilty by reason of insanity, citing postpartum psychosis. But 25 years later, turns out one of the state’s star witnesses, Dr. Avram Mack, who testified Clancy knew right from wrong and is criminally responsible for killing her kids, works for the very psychiatrist who was later proven to have falsely testified against Andrea Yates. Dr. Park Dietz said Andrea Yates replicated a “Law and Order” episode to get away with murder, but the episode never happened, and his testimony ultimately led to Yates getting a new trial where she was found not guilty by reason of insanity.
