From CNN.com:
Citing false testimony by a prosecution witness, an appeals court in Texas today ordered a new trial for Andrea Yates, the woman convicted in the drowning deaths of her five children. An expert witness for the state testified that Yates may have been influenced by an episode of the TV show “Law & Order” in which a woman who drowns her children in a bathtub is ruled insane. No such show ever aired. Yates was convicted in 2002 and sentenced to life in prison.
