The veteran Boston attorney previously fought Karen Read’s retrial after her 2024 trial ended without a verdict

The Massachusetts mother accused of strangling her three young children to dєatᩚh is bringing in the attorney who fought Karen Read’s retrial as she makes a bid to have her own case thrown out.

Lindsay Clancy, whose closely watched murder trial ended in a reported 11-1 split in favor of finding her not criminally responsible, has added veteran Boston attorney Martin Weinberg to her defense team.

Weinberg entered a limited appearance Tuesday to file and argue a forthcoming motion seeking dismissal on double-jeopardy grounds, according to a Plymouth Superior Court filing obtained by Fox News Digital.

The filing states Weinberg will represent Clancy in connection with the dismissal motion and “related matters.”

The filing does not say when Weinberg will submit the motion. Clancy’s case is next scheduled to return to court Sept. 29.

Judge William Sullivan declared a mistrial Sept. 4 after jurors spent seven days deliberating but said they could not reach a unanimous verdict.

Several jurors later revealed that 11 members of the panel supported finding Clancy not guilty by reason of lack of criminal responsibility, while one juror voted to convict.

Clancy’s longtime defense attorney, Kevin Reddington, signaled immediately after the mistrial that he would fight any attempt to put her on trial again.

The defense is expected to argue that the way the mistrial ended bars prosecutors from taking another shot at the case. Prosecutors can generally retry a defendant after a jury deadlocks, but Clancy’s attorneys are expected to claim that the circumstances surrounding her mistrial make a second trial improper.

Weinberg mounted a similar fight for Read after her 2024 trial ended without a verdict.

Read’s attorneys said jurors later told them they had unanimously agreed to clear her of second-degree murder and leaving the scene of a deadly 𝔠r𝘢sh, despite remaining divided on a manslaughter charge.

Weinberg argued that Read should not face those two charges again. A judge rejected the request, finding that the jury never formally returned not-guilty verdicts and that Read’s attorneys had agreed to the mistrial.

The battle continued in state and federal court before Read was retried in 2025. She was acquitted of second-degree murder, manslaughter and leaving the scene of a deadly 𝔠r𝘢sh but convicted of misdemeanor operating under the influence.

Clancy is accused of strangling her three children, Cora, 5, Dawson, 3, and 8-month-old Callan, with exercise bands inside the family’s Duxbury home in January 2023.

She then jumped from a second-story window in an apparent sᩚuᩚiᩚcide attempt, leaving her paralyzed, authorities said.

Clancy does not deny 𝘬iᩚlling the children but pleaded not guilty because her attorneys say she was not criminally responsible at the time. Her defense argued she was suffering from postpartum psychosis and was heavily medicated when the children died.

Prosecutors countered that Clancy carefully planned the killings, sending her husband, Patrick Clancy, out of the house before attacking the children.

Clancy remains in custody at Tewksbury Hospital. Prosecutors have not publicly announced whether they intend to retry her.

Sullivan also ordered the identities of the 12 jurors and six alternates who served in Clancy’s trial to remain private indefinitely amid safety concerns and the unauthorized disclosure of jurors’ personal information.

The judge wrote that jurors had been identified without their permission and that at least one juror had asked for the protection to be extended indefinitely.

“Based on the circumstances of this trial and the fact that the case continues to receive daily, divisive attention in Massachusetts and beyond, the Court concludes that there is a real and present ‘risk of [personal] harm to the jurors [and] to the integrity of their service,’” Sullivan wrote in the order obtained by Fox News.

Sullivan also found “a risk of immediate and irreparable injury” if the juror list were made public. The order does not prevent jurors from identifying themselves or speaking with the media if they choose.

In a separate order, Sullivan temporarily extended the protection covering the names of the larger pool summoned for jury duty from July 20 through July 24. Those names will remain impounded for another 10 days because of concerns about juror safety.
