Prosecutors in the Lindsay Clancy case are asking a judge to let jurors hear Patrick Clancy’s 911 call, saying his frantic report after finding their three children in the basement helps prove the killings were deliberate. The filing comes ahead of the summer murder trial, where prosecutors want to use the call, along with the placement of exercise bands around the children’s necks, to counter her claim that postpartum psychosis drove the deaths.

Patrick Clancy stayed on the line after first responders arrived and described discovering each child in the home’s basement. In the call, he can be heard yelling, “She killed the kids!” Prosecutors say that spontaneous reaction, along with the way the bands were used, gives jurors insight into whether the neckties were tied or merely looped, a distinction they say matters because it could show whether Lindsay Clancy tied the bands around each child’s neck and walked away or manually pulled them tighter until the children died. Each child was strangled with a separate exercise band, prosecutors said, and they argue the evidence points to deliberateness and to extreme atrocity and cruelty.

Clancy, 35, does not deny killing her three children. In pretrial motions, she has said she was suffering from postpartum psychosis when she strangled them before throwing herself from a second-story window. Prosecutors are pressing a different theory. They say Patrick Clancy previously told police and the grand jury that he believed the band at Cora’s neck and the one at Callan’s neck were tied with knots at the back, while the band on Dawson was tighter and had to be pulled over the child’s head. He also said the bands seemed looped like shoelaces and came off easily. That version, prosecutors argue, is inconsistent with an accidental or impulsive act and supports the state’s claim that the killings were planned and carried out with force.

The request reaches beyond the 911 recording. The Commonwealth also wants jurors taken to view three locations, including the Duxbury house where the children were killed. The property was sold to a third party in Jan. 2024, and at a hearing in May prosecutors said the current homeowner objects to the viewing. They argued crime scene photos and videos do not give a complete picture of the residence, and they proposed limiting access to the house to the attorneys, jury and judge. A virtual court hearing was held on Nov. 18, 2025, and the judge now has to decide whether the call and the site visit will be part of the case jurors hear this summer.
