A judge has declared a mistrial in the Lindsay Clancy murder case after jurors said they could not reach a unanimous verdict on whether she was criminally responsible for killing her three young children.
The mistrial, in the seventh day of deliberations, leaves the case unresolved and allows prosecutors to try Clancy again.
Deliberations and jury conflict
The deliberations took a dramatic turn late in the week when the judge said he was going to declare a mistrial on Friday before suddenly changing course and giving her defence lawyer a chance to appeal to the state’s highest appeals court.
That came a day after the foreperson told the judge that a lone holdout was refusing to follow the court’s instructions about reasonable doubt, offering a rare glimpse at possible conflict inside the jury room. Clancy’s lawyer demanded the juror be kicked off the case.
Public attention and divided opinions
The livestreamed trial drew attention to maternal mental health after childbirth and was closely watched by a polarised public.
Clancy’s sympathisers saw her as a loving mother who had realised something was badly wrong in the months ahead of the killings and sought help, including checking herself in to a psychiatric hospital. Her detractors said she deserved to be punished for an evil and selfish act.
Prosecution and defence cases
Prosecutors said Clancy, a former labour and delivery nurse, acted deliberately when she strangled five-year-old Cora, three-year-old Dawson and eight-month-old Callan Clancy with exercise bands on January 24, 2023. They said she contrived to get her husband out of the house by sending him to pick up medicine for one of their children and dinner for the family.
Clancy’s lawyer, Kevin Reddington, never disputed that she killed the children, but says she should not be held criminally responsible because she had post-partum psychosis – a rare mental illness linked to the stress, sleep deprivation and hormonal changes that follow childbirth.
Mental health evidence
Over 21 days of testimony, jurors heard how Clancy’s mental health had collapsed after Callan’s birth. Deeply anxious about a planned return to work, unable to sleep and experiencing what she described as a disturbing brain fog, Clancy sought care from experts in post-pregnancy mood disorders, who prescribed multiple psychiatric medications.
Clancy’s family members testified that she expressed concern about her mental health decline. Her former mother-in-law, Susan Clancy, described her as a “very nurturing, very loving mother” who was “begging for help”.
In early January, she checked herself in to a psychiatric hospital for more intensive treatment, but her stay was short. She killed the children 19 days after she was discharged, leaving their bodies in the basement of the family’s home in coastal Duxbury, Massachusetts.
Clancy jumped from a second-story window immediately after and remains paralysed from the waist down.
Expert testimony
Prosecutors conceded that Clancy had severe mental illness, but insisted she was able to understand and control her actions. They emphasised that although she claimed to have heard a male voice commanding her to kill the children, she never disclosed hearing voices to her mental health providers before the killings.
In its latter stages, the trial became a battle of medical experts. Kirk Heilbrun, a forensic psychologist hired by prosecutors to evaluate Clancy, testified that he did not believe her story about having heard voices. And he said he did not believe she had acute psychosis when she killed the children, but rather took their lives so they would not “suffer” after she killed herself.
Dr Phillip Resnick, a forensic psychiatrist who testified for the defence, said that Clancy was “clearly psychotic” and was not in control of her actions. “It was almost like she was a puppet and someone else was pulling the strings,” said Dr Resnick, who spent hours interviewing Clancy after the killings. He said she was also likely experiencing bipolar disorder.
At the start of the trial, Clancy’s ex-husband Patrick Clancy described the horror of returning home to find his children. Prosecutors played a seven-minute 911 call in which he could be heard finding the bodies. In interviews, he has said he has forgiven her and believes her actions were the result of mental illness.
