Karen Read attorney joins Lindsay Clancy’s legal team in bid to get murder case tossed after mistrial

Another high-profile attorney has joined Lindsay Clancy‘s defense team following the mistrial in the Massachusetts mother’s murder case.

Veteran Boston attorney Martin Weinberg — who represented Karen Read in her fight to avoid a retrial on double-jeopardy grounds — has joined Clancy’s legal team as she seeks to prevent prosecutors from putting her on trial again for killing her three children.

Weinberg entered a limited appearance on September 15 to file and argue a forthcoming motion seeking to have Clancy’s case dismissed on double-jeopardy grounds.

Judge William Sullivan declared a mistrial on September 4 after jurors spent seven days deliberating without reaching a unanimous verdict.

Jurors later revealed that the panel was split 11-1, with 11 prepared to find Clancy not guilty by reason of lack of criminal responsibility and one juror voting to convict.

Weinberg is now preparing a motion arguing that double-jeopardy protections should prevent prosecutors from trying Clancy again. 

The double-jeopardy effort is separate from another attempt by Clancy’s longtime attorney, Kevin Reddington, to end the case.

On September 10, Reddington renewed a Rule 25 motion asking Sullivan to enter a required finding of not guilty on the grounds that prosecutors failed to present sufficient evidence to prove beyond a reasonable doubt that Clancy was criminally responsible when she killed her children.

“No rational jury could find beyond a reasonable doubt that she had no mental disease or defect when the Commonwealth’s own proof established that she did,” the defense argued in the motion.

The judge is expected to consider the Rule 25 request when Clancy’s case returns to court on September 29.

Prosecutors have not said whether they intend to retry Clancy if the defense’s efforts to end the case fail.

Weinberg pursued a similar double-jeopardy argument for Read after her first murder trial ended in a mistrial in 2024.

Read was accused of killing her boyfriend, Boston police officer John O’Keefe, by striking him with her SUV and leaving him outside a Canton, Mass., home in January 2022.

After the mistrial, Read’s attorneys said jurors had contacted them and indicated they had unanimously agreed to acquit her of second-degree murder and leaving the scene of a deadly crash but remained divided on a manslaughter charge.

Weinberg argued that retrying Read on the charges jurors reportedly had agreed to acquit her on would violate her protection against double jeopardy.

The Massachusetts Supreme Judicial Court ultimately rejected that argument, concluding that no verdict had been returned or recorded before the judge declared a mistrial.

Read was retried in 2025 and acquitted of second-degree murder, manslaughter and leaving the scene of a deadly crash. She was convicted of the lesser offense of operating under the influence.

Lindsay killed her children — Cora, 5, Dawson, 3, and Callan, 8 months — in the family’s Duxbury, Mass., home on January 24, 2023.

Prosecutors argued that she deliberately sent her husband, Patrick Clancy, out to pick up takeout and medication before strangling the children with exercise bands.

The defense did not dispute that Lindsay killed her children but maintained that she was not criminally responsible at the time because she was suffering from postpartum psychosis.

Her attorneys pointed to her extensive psychiatric treatment, multiple medications and writings documenting her deteriorating mental health. They also argued that she heard a male voice commanding her to kill the children and herself.

Prosecutors acknowledged that the former labor and delivery nurse was mentally ill but maintained that she was not psychotic when she killed the children and knew that what she was doing was wrong.

After the killings, Lindsay jumped from a second-story window in a suicide attempt and was left paralyzed. She remains in custody at Tewksbury State Hospital, a psychiatric facility.

Patrick, who testified during Lindsay’s trial, is also speaking publicly about the case in his first television interview.

In a 60 Minutes sit-down airing September 20, Patrick discusses his grief, memories of Cora, Dawson and Callan, and conspiracy theories that have circulated on social media since Lindsay’s trial.

Patrick told correspondent Ross Douthat that he still talks to his children “all the time” as a way to stay connected to them.

In an exclusive interview with 60 Minutes, Dr. Rachel Danis describes her husband Patrick Clancy as "the most selfless father and supportive partner."

His new wife, Dr. Rachel Danis, also joins him for part of the interview. She is a reproductive endocrinologist and infertility specialist who practices in New York City. The couple married earlier this year.
