DEDHAM − Advocates for Karen Read, a Mansfield woman accused of killing her Boston police officer The boyfriend, Braintree native John O’Keefe, asked Norfolk County District Attorney Michael Morrissey to be ordered to turn over personal emails and cellphone data before the second trial.

The defense, in its motion, alleges that Morrissey used his personal email and cellphone to communicate with Stoughton District Court staff and judges while Read’s case was previously pending in that court.

Judge Beverly Cannone declared a mistrial in the case in July. She scheduled a second trial to begin on January 27, 2025. The court confirmed last month that Cannone will oversee Read’s second trial.

The prosecution and defense filed a joint motion in Norfolk Superior Court on Monday asking for the trial to be postponed until April.

In separate filings Friday, Read’s attorneys are seeking relief from an order to seize a transcript of the sidebar that took place on April 14, 2024, and are also challenging the testimony of Shanon Burgess, the prosecution’s expert who examined the SUV Read’s Lexus.

Karen Read is charged with second degree murder

Read was charged with second-degree murder, manslaughter while operating under the influence and leaving the scene of injury and death after O’Keefe’s body was found outside the Canton home of a fellow Boston police officer , on January 29, 2022, during a snowstorm. Prosecutors say Read was drunk and angry when he intentionally hit him.

But Read’s defense attorneys say she was charged in O’Keefe’s death.

Read is also charged with manslaughter while driving while intoxicated and leaving the scene of bodily injury and death.

During the first trial, prosecutors called more than 65 witnesses in testimony that began on April 29.

The defense witness list was much shorter and included a plow driver who said he saw nothing on the Canton lawn where O’Keefe’s body was found.

Norfolk District Attorney Michael Morrissey announced last month that he had appointed Special Assistant District Attorney Hank Brennan to preside over Read’s retrial.
