Morrissey’s spokesman declined to comment because the case is pending, saying any “answers the office has will be given in court.”

Read44, of Mansfield, has pleaded not guilty to charges of second-degree murder, manslaughter under the influence and leaving the scene of injury resulting in death. Prosecutors claim she drunkenly backed into her SUV Boston Police Officer John O’Keefe early on Jan. 29, 2022, after dropping him off outside a residence in Canton after a night of bar hopping. Her lawyers say she was framed and that O’Keefe entered the house, which at the time was owned by another Boston police officer, where he was fatally beaten in the basement before his body was planted on the lawn.

Her fiThe first trial ended in a hung jury in July, and her new trial is currently scheduled for January. She remains free on bail.

The email from Morrissey that Read’s lawyers cited on Friday referred to Aidan Kearneya blogger known as “Turtleboy” who has championed her claims of innocence.

Kearney has pleaded not guilty to charges that he harassed witnesses in the Read case, and one of his attorneys, Mark A. Bederow, disclosed Morrissey’s emails in a filing last month.

On Sept. 28, 2023, Read witness Chris Albert requested a restraining order against Kearney during a public hearing in Stoughton District Court, where a judge denied the request, Bederow wrote. Kearney wrote about the hearing later in the day on his blog, prompting another Read witness, Jennifer McCabe, to text an unnamed person that “someone from the court leaked it right away” to Kearney, Bederow wrote.

McCabe’s message was forwarded to Morrissey, who included it in an email he sent to court administrators from a personal iCloud account expressing “great concern” about the alleged leak, even though the hearing was a public proceeding, Bederow wrote.

Morrissey’s email, which Bederow included in the filing, also named a Stoughton District Court employee, Michelle Littlefield, as the “lead individual presenting himself as a possible leaker.”

Morrissey wrote that his office was informed by several parties that shortly after the restraining order hearing, Kearney “was provided with the full affidavit. There is no way he would have been aware of the proceedings without an insider working at the courthouse.”

A trial court spokesman said Littlefield was placed on paid leave in October 2023 and terminated the following month.

“We are extremely concerned that the improperly disseminated court material unsolicited to a third party, which continues to cause injury and harm to a witness (sic) in an ongoing homicide case must be a violation of court policies or a potential violation of law,” Morrisey wrote officers of the court.

In Friday’s motion, Read’s attorneys said Morrissey’s email was inaccurate.

“DA Morrissey’s ex parte communications with trial judges, including the very judge who presided over Read’s case while it was pending in District Court, and his demands for ‘evidence and assurance(s)’ that ‘action’ had been taken by the Stoughton District Court, are extremely troubling and raises questions about the integrity of this prosecution,” they wrote.

The motion stated that Morrissey had said in his email that Albert and “others” informed him that Kearney obtained the restraining order, “indicating that a number of witnesses in this matter had contacted members of the prosecution team.”

Read’s lawyers said that while a “defendant need not make such a request to seek disclosure, Read is requesting that any “material, exculpatory evidence” contained in DA Morrissey’s private communications about her case — which is a matter of public interest — be revealed.”

Separatethe state supreme court is considering a request from Read’s lawyers to drop the murder and drop the charges against her, on the grounds that several jurors told themeither directly or through intermediaries, that the jury unanimously agreed to acquit her on these two counts.

In addition, Read faces a trial in case of death filed by O’Keefe’s family in Plymouth Superior Court.
