The jury could find her guilty of murder or the lesser crime of manslaughter, or it could acquit her if it finds that she wasn't in control of herself due to psychiatric problems.

While both sides agree she killed her children, Clancy's defense team argued she suffered from postpartum psychosis, with defense attorney Kevin Reddington stating that "lousy medical care" exacerbated her condition. Prosecutors argued she intentionally planned the killings and that the nation's healthcare system is "not on trial here."

Lindsay Clancy's murder trial hasn't just dominated headlines for its tragic story and true crime fascination. For many, it has prompted a groundswell of recognition and outrage around the barriers women face when seeking care, the lack of research on postpartum mental health conditions and little education for providers.

Kirk Heilbrun, who examined Clancy over three days this year, said he struggled to reach a diagnosis of bipolar 2 disorder "because of all the diagnoses in the records and all the symptoms that she experienced."

Researchers estimate that the condition — a mental health emergency that is less common than postpartum depression — afflicts 1 to 2 out of 1,000 women after delivery.

Clancy's lawyer, Kevin Reddington, hasn't disputed that she killed the children but says she should not be held criminally responsible because she had postpartum psychosis, a rare mental illness linked to the stress, sleep deprivation and hormonal changes that follow childbirth.
