Karen Read Trial Live: Jury Can't Reach Verdict — Did Professor Kill Her Police Officer Boyfriend? 

The jury in Karen Read's murder trial was unable to come to a verdict in a Boston court on Monday, July 1, and the judge has declared a mistrial, according to Boston.com, NBC Boston and MassLive.com.

The news came on the fifth day of deliberations for the jury, which was tasked with determining whether Read, 44, is guilty of second-degree murder in connection with the death of her boyfriend, Boston police officer John O’Keefe.

On Friday, June 28, shortly after noon, the jury told the judge that it was deadlocked, and it did so again on July 1. Both times, Judge Beverly Cannone sent jurors back to keep deliberating. However, they were still unable to come to a unanimous decision.

O'Keefe was 46 when he was found dead outside a house party at the home of then-Boston Police Officer Brian Albert in Canton, Mass., in the early hours of Jan. 29, 2022. A beloved member of the community, he had been raising a teenage niece and nephew whose parents had died.

Read — a college finance professor — was accused of drunkenly running over O’Keefe with her vehicle during a winter storm. He died from blunt force trauma and hypothermia, an autopsy revealed.

The Canton community has been at odds over who is responsible for the death of O'Keefe, who was found with two black eyes and deep cuts on the back of his head and right arm. Prosecutors claim that Read dropped O’Keefe off outside Albert’s house and then hit him with her Lexus SUV while driving intoxicated.

According to the prosecution, Read had allegedly told a friend she caught her boyfriend kissing another woman on vacation earlier that year, and O’Keefe’s niece told police the couple had previously argued when O’Keefe allegedly told Read their relationship was “toxic.” 

However, Read’s defense attorneys have argued that O’Keefe, who allegedly had a long-standing disagreement with someone at the party, was injured during an argument and may have been the victim of a dog attack.

The defense has also claimed that Read is the victim of a cover-up by police. “Karen Read was framed,” attorney David Yannetti said in opening statements in April. “She did not cause his death, and that means somebody else did.”

Read's attorneys allege that authorities planted evidence to protect one of their own.
