Lindsay Clancy Trial: Prosecution Fights to Save Its Psychiatrist After Brutal Cross

The prosecution spent Monday's redirect trying to put Dr. Avram Mack back together after Kevin Reddington's cross-examination left him bruised in the murder trial of Lindsay Clancy — the Duxbury, Massachusetts mother accused of strangling her three children, 5-year-old Cora, 3-year-old Dawson, and 7-month-old Callan, with exercise resistance bands inside the family's Summer Street home on January 24, 2023. Clancy faces three counts of murder and three counts of strangulation, has pleaded not guilty, and is mounting an insanity defense built on claims of severe postpartum psychosis and psychiatric overmedication.

Prosecutors used their redirect to walk Mack through something the defense hadn't dwelled on: that "postpartum onset" exists as a specifier within diagnoses like bipolar disorder and major depression, even if postpartum psychosis itself isn't a standalone DSM entry. It's a technical point, but it's the kind of technical point that can quietly undercut a defense theory without anyone raising their voice. Beyond that, the redirect stayed in the weeds — definitions of what "postpartum" actually covers clinically, more on Mack's qualifications, and other procedural cleanup. No bombshells here, just two sides fighting over the credibility of one witness inch by inch, Reddington working to keep the earlier damage intact, prosecutors working to patch it.

It's not the most cinematic day of testimony, but it matters — juries remember whether an expert held up under pressure, and this was the prosecution's chance to make sure Mack's opinion still counts for something. After the killings, Clancy allegedly attempted suicide by jumping from a second-story window, leaving her paralyzed from the waist down. Her husband, Patrick Clancy, was out running errands at the time and has since relocated to Manhattan. The trial continues in Plymouth Superior Court.
