Jurors began a sixth day of deliberations in the closely watched murder trial of Lindsay Clancy, a former nurse who strangled her three young children in January 2023. The jury has been deadlocked since at least Tuesday morning, but a judge has urged them to keep trying to reach a verdict.

Failure would result in a mistrial, and prosecutors would have to decide whether to try again for a conviction. The wrenching case has sharply divided Americans over whether Ms. Clancy, 36, should be held criminally responsible, and cast scrutiny on access to care for new mothers struggling with mental health.
