Trial of Massachusetts Mother Accused of Killing Children

The husband of Lindsay Clancy, a Massachusetts mother facing charges for the murder of her three young children, is expected to support her in court. This week, Clancy, a 35-year-old former nurse, will be tried in Plymouth Superior Court for the deaths of her children, aged 5, 3, and 8 months. Jury selection starts Monday morning.

Patrick Clancy, among over 200 potential witnesses, backs his wife’s claims. Both allege that doctors’ misdiagnosis and medication overdose led to her hearing voices, which directed her to commit the tragic acts. These claims are central to lawsuits asserting medical professionals failed to identify her postpartum psychosis.

Lindsay Clancy did everything a mother in her situation could do, the lawsuit states, explaining her repeated attempts to seek treatment and communicate her worsening condition.

In a filed complaint in Norfolk Superior Court, Lindsay Clancy claims misdiagnosis and mistreatment by psychiatric providers. She alleges they mislabeled her condition as bipolar disorder with postpartum onset and mismanaged her medication routine, which she believes deteriorated her mental state before the tragedy on January 24, 2023.

The complaint asserts medical negligence and malpractice, arguing that providers failed to address her ‘intrusive thoughts,’ which were dangerous auditory hallucinations threatening her children’s safety.

According to the document, Clancy, who had been a registered nurse at Massachusetts General Hospital, displayed hypomania post-childbirth in May 2022. By 12 weeks postpartum, her condition included severe anxiety, depression, and insomnia.

Seeking psychiatric help in September 2022, Clancy was prescribed Zoloft. After a dosage increase, she experienced insomnia, racing thoughts, and heightened anxiety. The lawsuit argues these effects were warning signs of medication-induced activation and possible bipolar disorder. Clancy was allegedly prescribed various medications without proper evaluation or provider coordination.

Following a session with Remeron in late November 2022, she purportedly became disoriented. After Seroquel, she exhibited suicidal thoughts and heard voices indicating harm to herself. Her husband noted her distress to her medical team, emphasizing voices disturbing her daily.

The lawsuit further notes that Clancy admitted to family about having thoughts of harming the children and fearing involuntary confinement, prompting her to seek hospital care in December 2022. Despite efforts, Clancy’s condition worsened, according to the complaint.

In outpatient care in January 2023, Clancy’s condition continued declining. She reported hallucinations urging harm to the children and herself. A day after a dose increase of Amitriptyline on January 23, Clancy’s severe depression allegedly led to the tragic day.

Clancy’s lawsuit names several providers and institutions, seeking damages for her physical injuries, psychological trauma, medical costs, lost income, and lifelong impacts on her family life. The trial opens Monday, July 20.
