A judge declared a mistrial Friday in the murder trial of Lindsay Clancy.

Jurors could not reach a verdict.

The case drew intense national attention to maternal mental health after childbirth.

Clancy, a 36-year-old former labor and delivery nurse, admitted to killing her three children in 2023.

Her lawyer argued she had postpartum psychosis, a rare mental illness.

Prosecutors said she knew what she was doing when she strangled the children, aged 5, 3, and 8 months.

The mistrial came on the seventh day of deliberations.

Clancy's lawyer blamed one juror for blocking a verdict.

He said the juror would not follow the judge's instructions.

The prosecutor said there would be no immediate decision about a second trial.

He added that public opinion would not be a factor.

Clancy remains charged with murder.

She is expected to stay at a psychiatric hospital.

Her ex-husband, Patrick Clancy, has said he forgives her.

He believes her actions resulted from mental illness.

His lawyer said the prospect of another trial is "extraordinarily painful."
