Andrea Yates
Dietz attracted considerable controversy following his testimony in the 2002 trial of Andrea Yates, a woman convicted of drowning her five children in a bathtub. Dietz was the prosecution's lone mental health expert, and testified that shortly before Yates committed the crime, Law & Order had aired an episode about a woman who drowned her children and was found innocent by reason of insanity. No such Law & Order episode existed, and when the error became known, Yates' murder conviction was overturned by an appeals court. The negative publicity following the Yates trial led Dietz to be dropped as an expert from Marcus Wesson's murder trial.
