Prosecutors presented excerpts from Lindsay Clancy’s personal diary as her murder trial entered its second week, offering jurors a glimpse into the emotional and psychological struggles she described before the deaths of her three children.
Clancy is facing three murder charges in connection with the January 2023 deaths of her children, Cora, 5, Dawson, 3, and 8-month-old Callan, who were killed inside the family’s Duxbury, Massachusetts, home.
While Clancy has not disputed that she killed her children, her defense maintains that she was suffering from postpartum psychosis and therefore should not be considered criminally responsible for her actions.
Prosecutors, however, argue that the killings were deliberate. During proceedings on Monday, Aug. 3, Plymouth County Assistant District Attorney Shanan Buckingham read passages from Clancy’s diary while questioning Massachusetts State Police investigator Cory Melo.
One entry described the intense pressure Clancy said she was experiencing while caring for her children.
“I feel like I’m drowning every day,” she wrote, according to the testimony.
In another passage, Clancy described herself as “completely overwhelmed” by the responsibility of caring for her children.
The defense later highlighted other portions of the diary during cross-examination. Attorney Kevin Reddington pointed to entries in which Clancy wrote about experiencing “brain fog” and feeling “completely disconnected with my baby.”
The competing interpretations of those entries are central to the case.
Prosecutors have used Clancy’s writings and other evidence to support their argument that she intentionally killed her children. The defense, meanwhile, has emphasized her descriptions of severe psychological distress as part of its argument that she was experiencing postpartum psychosis.
Clancy’s diary was discussed during the same day that medical professionals testified about the injuries she suffered after the killings.
According to testimony from emergency room physician Kelly McDonough, Clancy had “superficial lacerations” on her wrists after she jumped from a second-story window. The fall caused severe spinal injuries and left her paralyzed from the waist down.
Prosecutors’ questions about the nature of those injuries appeared to challenge the defense’s portrayal of the incident as a genuine suicide attempt.
Reddington addressed that issue directly during his opening statement, telling jurors, “This is no fake suicide.”
Clancy’s former husband, Patrick Clancy, discovered her injured outside the family home before finding their children inside. He has publicly said that he forgives Lindsay and has supported the defense’s focus on her mental health struggles.
The trial is expected to continue for several more weeks, with prosecutors and defense attorneys presenting competing accounts of Clancy’s mental state and actions leading up to the deaths of her children.
