In the harrowing trial of Lindsay Clancy in Plymouth Superior Court, Massachusetts, one of the most intimate pieces of evidence has emerged: her private diary. The handwritten journals, seized by state police from the family home in Duxbury after the tragic events of January 24, 2023, have been read aloud to the jury, offering an unprecedented window into the mind of the 35-year-old mother accused of murdering her three young children—Cora (5), Dawson (3), and Callan (8 months)—before attempting suicide herself.

The entries, spanning late 2022 and early 2023, paint a picture of a mother grappling with severe anxiety, insomnia, “brain fog,” and deepening despair. Defense attorneys have used them to argue that Clancy suffered from postpartum psychosis and other mental health crises that stripped her of the ability to understand right from wrong. Prosecutors, however, insist the writings do not absolve her of criminal responsibility, framing her actions as deliberate.

One passage has particularly captivated observers. In it, Clancy expressed a raw desperation: “It’s like I’m so desperate to get a mental break from taking care of everyone that my mind is trying to make something physically wrong with me.” This line, dated November 18, 2022, has been dissected by both sides, with defense lawyers highlighting it as evidence of her fracturing reality and prosecutors viewing it as a chilling prelude to the violence.

The journal excerpts were introduced during testimony from State Police Trooper Cory Melo, who helped search the home. Prosecutor Shanan Buckingham read passages showing Clancy’s growing guilt and overwhelm. She described being “completely overwhelmed trying to take care of the three kids” and feeling as though “I’m drowning every day.” Another undated entry read: “I’m completely overwhelmed, trying to take care of the three kids. I feel like I’m drowning every day.”

On cross-examination, defense attorney Kevin Reddington focused on earlier entries tied to the sleep training of their youngest child, Callan. Clancy wrote that allowing him to cry without intervening “just about killed me” and even admitted saying “I want to die” to her husband Patrick while the baby cried for over an hour. She added that anxiety intensified after the sleep training: “I have horrible insomnia and anxiety which is causing depression. I have no appetite. I don’t know what’s wrong with me. I want help. I want to be well.”

Additional passages detailed “crazy brain fog” and a sense of disconnection. “I feel completely disconnected with my baby,” she wrote. “I feel like I’m going through the motions every day.” She expressed terror about returning to work as a labor and delivery nurse at Mass General Hospital, fearing she could not function amid the fog. Entries also touched on marital strain: “I feel horribly guilty about my marriage. I want to connect with Pat again. I’m terrified of the relationship.”

Many entries were undated, while others tracked medication use. One detailed page included 5 mg of Valium and 75 mg of Seroquel, with notes about waking “feeling very depressed” and “horrible intrusive thoughts.” Clancy’s defense contends she was prescribed 15 psychiatric medications over three months and had seen multiple doctors, including two hospital stays. They argue this cocktail, combined with undiagnosed bipolar disorder and postpartum psychosis, created a state where she was not criminally responsible.

Prosecutors counter that the writings do not erase intent. They point to her questions in the hospital shortly after the attempt—“Is my body broken?” and “Do I have a lawyer?”—as evidence she knew what she had done. The central question before the jury remains whether Clancy understood the nature and wrongfulness of her actions when she allegedly strangled the children with exercise bands in the basement while Patrick was out.

The diary reads are expected to continue as the trial progresses. Both sides have used the journals strategically: the defense to humanize Clancy as a loving mother consumed by illness, and the prosecution to show a mother who chose a horrifying path amid distress. As the jury weighs the evidence, the diary’s haunting pages—filled with pleas for help, guilt, and moments of clarity—will likely play a pivotal role in determining whether Lindsay Clancy is held fully accountable for her crimes or if her profound mental suffering demands a different path.
