Story summary

Lindsay Clancy pleaded not guilty to the Jan. 24, 2023 deaths of her two children in Duxbury.
Patrick Clancy arrived and found Lindsay injured and the children dead in the basement.
The defense says she suffered postpartum psychosis and bipolar disorder diagnosed after the killings, and that a not-guilty verdict would lead to commitment to a state mental-health facility, while a conviction would impose life without parole.

History

Historical Context

In June 2001 Andrea Yates drowned her five children in Houston, and her 2002 capital-murder conviction—later overturned after Dr. Park Dietz’s false testimony—led to a 2006 not-guilty by reason of insanity verdict, exposing Texas’s strict M'Naghten-based insanity rule. The case ignited nationwide debate on postpartum psychosis and prompted tighter forensic-psychiatry standards that now guide courts assessing maternal mental illness.
