Michael P. Desronvil, the lone holdout juror in Lindsay Clancy’s murder trial, has spoken publicly for the first time, pushing back against claims from fellow jurors that he acknowledged having reasonable doubt but still refused to join them in finding Clancy not guilty by reason of insanity.
In a statement provided to NewsNation, Desronvil said he remained convinced throughout deliberations that prosecutors had presented enough evidence to establish that Clancy knew what she was doing when she killed her three children in January 2023.
“I didn’t have any doubts,” Desronvil said. He explained that when he tried to discuss different theories during deliberations, other jurors interpreted those discussions as signs that he was uncertain about the prosecution’s case.
“Based on all the physical evidence, key witnesses, and what the prosecution presents, I thought it was enough proof that she knew exactly what she was doing and planned,” he said.
His account differs sharply from statements made by several other jurors following the mistrial. Jury foreperson Ronni Carlson previously said Desronvil had acknowledged having reasonable doubt but nevertheless refused to vote for a finding that Clancy was not criminally responsible because of insanity.
Other jurors also criticized his approach to the deliberations.
The disagreement became central after the 12-member jury failed to reach a unanimous verdict. Eleven jurors were prepared to find Clancy not criminally responsible, while Desronvil remained opposed. After more than seven days of deliberations, Judge William Sullivan declared a mistrial on September 4.
Clancy was accused of killing her three children — 5-year-old Cora, 3-year-old Dawson and 8-month-old Callan — at the family’s home in Duxbury, Massachusetts, on January 24, 2023. She has acknowledged killing the children, while her defense argued that she was suffering from postpartum psychosis and should therefore be found not criminally responsible.
Prosecutors presented evidence aimed at showing that Clancy understood her actions and had planned the killings.
They argued, among other things, that she arranged for her husband to leave the home by sending him on errands before the killings. Prosecutors also pointed to evidence concerning her communications with medical providers and her behavior before the deaths.
The defense, however, maintained that Clancy was experiencing severe postpartum psychosis and that her mental condition prevented her from understanding that her actions were wrong.
Her attorneys have argued that the prosecution’s own evidence established that she was seriously mentally ill at the time of the killings.
The mistrial has left the case unresolved. Prosecutors have not yet announced whether they will seek a new trial. Meanwhile, Clancy’s defense team has asked the court to dismiss the case, arguing that a retrial would violate protections against double jeopardy. Judge Sullivan is scheduled to hear arguments related to the case on September 29.
Desronvil’s statement adds another layer to a case that has already drawn intense public attention. His account and the accounts of the other jurors differ over what happened inside the jury room, but the legal outcome remains unchanged: the jury did not reach the unanimous verdict required, and the case ended in a mistrial.
