When the Karen Read Trial Starts: Full Timeline, Retrial Schedule, and Legal Context

The first Karen Read trial officially began with jury selection on April 16, 2024, at the Norfolk Superior Court in Dedham, Massachusetts. Following a mistrial declared on July 1, 2024, the Commonwealth scheduled the retrial to begin on January 27, 2025. These dates represent the critical milestones in a legal saga that has garnered international attention.

The case of Commonwealth v. Karen Read is one of the most complex and polarized motor vehicle homicide trials in recent Massachusetts history. It involves allegations of second-degree murder, claims of a wide-ranging law enforcement cover-up, and a federal investigation into the handling of the initial probe. For those tracking the proceedings in 2026, understanding the start dates requires a look at both the original 2024 trial and the subsequent 2025 retrial, as well as the procedural hurdles that defined the interim period.

The Origins of the Karen Read Case

To understand why the trial schedule shifted and why the start dates were so hard-fought, one must look at the events of January 29, 2022. Karen Read, a former Bentley University adjunct professor, was accused of hitting her boyfriend, Boston Police Officer John O’Keefe, with her Lexus SUV and leaving him to die in a snowstorm outside a home in Canton, Massachusetts.

The home belonged to another Boston Police officer, Brian Albert. Read was arrested and initially charged with manslaughter, but the charges were later upgraded to second-degree murder, leaving the scene of a motor vehicle accident resulting in death, and manslaughter while operating under the influence.

The Initial Investigation and Indictment

The investigation led by the Massachusetts State Police, specifically Trooper Michael Proctor, became the focal point of the defense’s strategy. Read’s defense team, led by Alan Jackson and David Yannetti, alleged that O’Keefe was actually beaten inside the Albert home and his body was moved outside, while Read was framed by a group of well-connected individuals, including members of law enforcement. This "third-party culprit" defense created a massive divide in public opinion and led to significant pre-trial delays as both sides litigated the discovery of evidence.

The First Trial: April 16, 2024

After two years of pre-trial motions and intense media scrutiny, the first trial finally commenced on April 16, 2024. The start date was preceded by several postponements as the defense sought access to federal grand jury testimony and cellular data.

Jury Selection and "Voir Dire"

Jury selection lasted nearly two weeks. In a case with this level of notoriety, the process of "voir dire"—where potential jurors are questioned about their biases—was particularly grueling. Judge Beverly Cannone presided over the proceedings, overseeing the selection of 17 jurors (12 deliberating and 5 alternates). The court had to ensure that the intense "Free Karen Read" movement, which frequently protested outside the courthouse, did not unfairly influence the panel.

Opening Statements and Testimony

Opening statements began on April 29, 2024. The prosecution, led by Assistant District Attorney Adam Lally, argued that Read’s broken taillight and her own statements on the morning O'Keefe was found ("I hit him, I hit him, I hit him") were definitive proof of guilt.

The defense countered with expert testimony regarding the injuries O'Keefe sustained, which they argued were inconsistent with a vehicular strike and more consistent with a physical altercation and a dog attack. The trial lasted ten weeks, featuring over 70 witnesses and hundreds of exhibits.

The July 2024 Mistrial

The first trial ended abruptly on July 1, 2024. After five days of deliberations, the jury informed Judge Cannone that they were "starkly divided" and unable to reach a unanimous verdict on any of the charges.

The Hung Jury and "Tuey-Rodriguez" Charge

When a jury is deadlocked, Massachusetts judges typically issue a "Tuey-Rodriguez" charge—an instruction that encourages jurors in the minority to reconsider the evidence and the opinions of the majority without surrendering their honest convictions. Despite this instruction, the jury remained deadlocked, leading the judge to declare a mistrial.

Immediately following the mistrial, the Norfolk County District Attorney’s Office announced its intent to retry the case, sparking a new round of legal battles over the retrial start date and the validity of the original charges.

The Retrial Schedule: January 27, 2025

Following the mistrial, the court moved to set a new date for the proceedings. During a status hearing in late 2024, Judge Cannone set January 27, 2025, as the start date for the retrial.

Challenges to the Retrial

The period between the mistrial and the January 2025 start date was marked by unprecedented legal maneuvers. Read’s defense team filed motions to dismiss the second-degree murder and leaving the scene charges, claiming that they had received communications from jurors after the mistrial stating that the jury had actually been unanimous in finding Read "not guilty" on those two specific counts, only deadlocked on the manslaughter charge.

The defense argued that retrying her on the murder charge would constitute "double jeopardy," a violation of the Fifth Amendment. However, because the jury had not formally moved to acquit on any counts in open court, Judge Cannone denied the motion. This decision was appealed to the Massachusetts Supreme Judicial Court (SJC), which ultimately allowed the retrial to proceed as scheduled.

Key Milestones in the Karen Read Legal Timeline

The following table summarizes the primary dates associated with the Karen Read trial process.

Technical Depth: Why the Start Date Mattered

In a high-profile criminal case, the start date is more than just a calendar entry; it dictates the "shelf life" of evidence and the availability of expert witnesses.

Forensic and Digital Evidence

One reason for the lengthy gaps between the incident, the first trial, and the retrial involved the digital forensics of the "Canton 9" and the Lexus's infotainment system. The defense focused heavily on a Google search for "hos [sic] long to die in cold" allegedly made by Jennifer McCabe, a witness, hours before O'Keefe's body was officially discovered. Technical experts spent months debating the timestamp of this search, and the delay in the trial allowed for more refined forensic analysis from third-party experts.

The Federal Investigation

Unusually, the U.S. Attorney’s Office for the District of Massachusetts launched an independent investigation into the investigation of John O'Keefe's death. This federal probe loomed over the state trial. The start of the April 2024 trial was heavily influenced by when the federal government released thousands of pages of documents to both the prosecution and the defense. This "Brady" material (exculpatory evidence) was crucial for the defense's theory of a cover-up.

The Role of the Supreme Judicial Court (SJC)

As the case progressed toward the 2025 retrial, the Massachusetts SJC became a critical player. The defense's pursuit of a dismissal based on double jeopardy required the highest court in the Commonwealth to weigh in on how mistrials are handled.

Under Massachusetts law, if a jury does not return a verdict in open court, the counts remain "open." The defense’s attempt to use post-trial juror affidavits was a novel legal approach in the state. The SJC’s involvement underscored the high stakes of the Karen Read case, as any ruling could potentially change how trial judges poll juries in future deadlocked cases.

Media and Public Perception

The start of both the 2024 and 2025 proceedings was marked by significant public demonstrations. The "Free Karen Read" movement, bolstered by local bloggers and independent media, created a unique environment for the trial. The court had to implement "buffer zones" to keep protesters a certain distance from the courthouse to prevent jury intimidation.

The transparency of the trial—broadcast live by several outlets—allowed the public to see the complexities of the Massachusetts rules of evidence in real-time. This level of access is rare for Norfolk County and contributed to the case becoming a national talking point.

FAQs About the Karen Read Trial Dates

Why did the first Karen Read trial take so long to start?

The first trial was delayed primarily due to discovery issues. Because of the parallel federal investigation into the local police's handling of the case, a massive amount of evidence (including thousands of pages of grand jury testimony) had to be reviewed and turned over to the defense. Additionally, both sides filed numerous pre-trial motions regarding expert witness testimony and the admissibility of the "third-party culprit" defense.

Can the January 2025 retrial be delayed?

In the Massachusetts court system, trial dates can be moved due to "continuances" requested by either the prosecution or the defense. Common reasons for delays include the discovery of new evidence, the unavailability of a key witness, or pending rulings from higher courts like the SJC. However, as of the late 2024 scheduling, January 27, 2025, was the firm date set by the court.

What are the specific charges Karen Read faces in the retrial?

Karen Read continues to face three primary charges:

1. Second-degree murder: Alleging she intentionally or with extreme atrocity killed John O'Keefe.
2. Manslaughter while operating under the influence: Alleging her intoxication caused the death.
3. Leaving the scene of a personal injury or death: Alleging she knew she hit him and failed to stop.

Will the same judge preside over the retrial?

Yes, Judge Beverly Cannone was assigned to the case and presided over the first trial. Despite defense motions for her to recuse herself due to allegations of bias, she remained on the bench for the 2024 proceedings and the scheduling of the 2025 retrial.

Is the Karen Read trial televised?

The 2024 trial was televised and live-streamed by several major news networks and local Boston stations. Massachusetts generally allows cameras in the courtroom at the judge's discretion, and given the immense public interest, the 2025 retrial was also expected to be accessible to the public via broadcast.

Practical Recommendation for Following the Case
