While both sides agree she killed her children, Clancy’s defense team argued she suffered from postpartum psychosis, with defense attorney Kevin Reddington stating that "lousy medical care" exacerbated her condition. Prosecutors at the Plymouth County District Attorney’s office argued she intentionally planned the killings and that the nation’s healthcare system is "not on trial here."
Prosecutor Jennifer Sprague ended her closing argument describing how horrific and cruel the killings were.
“She left them discarded on the basement floor like broken toys because she was done playing the game,” Sprague says. “You know to a moral certainty she is guilty.”
Sprague alleges Clancy sent her then-husband to get some take-out food at a local restaurant to give her time to kill the children. She even checked a map to see how long it would take him to collect the food and return home.
“What she needed to know was how long specifically on that night it would take to get there,” Sprague says, “because she knew she would have a limited amount of time to do what she wanted to do. And what she had decided to do was to kill the children and then kill herself.”
Clancy's lawyer, Kevin Reddington told the jury that Clancy ’lived for her kids” but after she starting seeing a doctor, “it was not a wonderful life anymore.”
“You have the medical records. You heard the testimony. You know her concerns. You know her fears,” Reddington said. “Does this sound like a young lady that didn’t care and wanted to score more drugs off somebody? That’s another repulsive allegation.”
Reddington held up a posterboard with some of Clancy’s desperate writings as her mental health deteriorated.
He said she was in “the depths of the despair” before the killings.
