Lindsay Clancy built a seemingly idyllic life with her husband and three young children—all under the age of 6—in Duxbury, Massachusetts. However, prosecutors allege that image was shattered in January 2023 when Clancy brutally strangled her kids to death.

Clancy, 36, is accused of three counts of first-degree murder and pleaded not guilty to all charges. Her defense team contends she suffered from undiagnosed postpartum psychosis at the time of the killings.

Clancy’s high-profile trial ended in a mistrial on September 4 after the jury couldn’t reach a verdict, leaving open the possibility for a retrial.

Here’s everything we know about Clancy’s background, the alleged murders, and what happened during her trial.
