A murder trial is underway in Massachusetts, with details emerging about a tragic incident. A father discovered his three children dead in the basement of their home. He alerted police officers, who were initially tending to his then-wife, Lindsay Clancy, after she jumped from a second-floor window.

The officers rushed to the basement after the father's frantic alert. The trial is examining Clancy's mental state at the time of the incident. Her lawyers acknowledge she strangled the children but claim she was experiencing postpartum psychosis.

Further details about the case are available from the source, including testimony from police officers, firefighters, and paramedics who responded to the scene.
