Jury deadlocked in trial of Lindsay Clancy, accused of killing her three children

A deadlocked jury was sent back to deliberate Thursday as Plymouth Superior Court teeters on the brink of a mistrial in the trial of Lindsay Clancy, the former nurse accused of strangling her three young children to death in their basement.

The 12 jurors told Judge William Sullivan for a second time that they are hopelessly split over whether the 36-year-old mother was sane when she killed Cora, 5, Dawson, 3, and 8-month-old Callan in 2023.

Clancy sat stone-faced as Sullivan issued a high-stakes Allen charge Wednesday afternoon, ordering jurors not to surrender their honest convictions, but begging them to rethink their stances before forcing a hung jury.

"No one knows that another jury would be more intelligent, more impartial, or more competent to decide this than you," Sullivan warned the room.

The explosive, livestreamed courtroom drama has gripped the nation, pitting horrified observers who demand justice for the murdered infants against advocates who point to the terrifying realities of postpartum psychosis.

Clancy—who remains paralyzed from the waist down after plunging from a second-story window immediately after the killings—does not dispute that she strangled the children with exercise bands.

Her defense team insists she was driven by command hallucinations, claiming an internal voice ordered her to slaughter her children and take her own life. Relatives and medical experts testified to her harrowing mental collapse, revealing she was prescribed a cocktail of psychiatric medications following a stay in a mental facility. Her ex-husband, Patrick Clancy, has publicly forgiven her, insisting she was "ill, not evil."

Prosecutors paint a far more calculated picture of murder. They allege Clancy plotted the slayings by intentionally sending her husband out to run errands before carrying out the violence, and they have openly questioned whether her subsequent suicide attempt was genuine.

If the jury deadlocks permanently, Sullivan will declare a mistrial, leaving prosecutors to decide whether to retry Clancy, offer a plea deal, or drop the charges.

If convicted, the former labor and delivery nurse faces life behind bars for murder or manslaughter. If found not guilty by reason of insanity, she could still be committed to a state psychiatric facility indefinitely as a danger to the public.
