History

Historical Context

In 1995, Andrea Yates was convicted in Florida of drowning her five children, a case that spotlighted postpartum psychosis as a legal defense. The prosecution, led by State Attorney Harry Shorstein, presented forensic psychiatrist Dr. Michael Welner’s testimony, estimating a $1.5 million cost to the state for the ensuing appeals. Today's Massachusetts jury deadlock over nurse Lindsay Clancy mirrors Yates’s trial, as both defendants invoke severe postpartum mental illness to contest criminal culpability. The Yates precedent prompted the 2002 federal amendment to the Insanity Defense Reform Act, shaping how courts evaluate psychotic episodes in maternal homicide cases.
