The Karen Read Murder Trial: Canton Confidential

Published: Tue Jun 10 2025

A forensic pathologist called by Karen Read's defense was insistent that the evidence shows her SUV didn't hit John O'Keefe — and while she was prohibited from saying his arm injury was caused by a dog bite, Judge Cannone did give the defense a partial victory on the subject. Then, the defense called what's believed to be their final witness, and the ARCCA biomechanist also testified that the evidence doesn't suggest O'Keefe was hit by a vehicle. Plus, a juror's surprise note for the judge, how the jury appears to be holding on with the end finally in sight and whether the defense will

Summary

The Karen Read Murder Trial: Canton Confidential Episode: The Last Defense Witnesses Share a View on O'Keefe's Injury Release Date: June 10, 2025

Introduction

In this pivotal episode of Canton Confidential, NBC10 Boston provides an in-depth analysis of the latest developments in the Karen Read murder trial. As the trial edges closer to its conclusion, the focus shifts to the defense's final witnesses and their testimonies regarding the injuries sustained by John O'Keefe, the murdered Boston Police Officer. This episode delves into the nuances of the expert testimonies, legal maneuvers, and the jury's reception of the evidence presented.

Today's Testimony Overview

The episode begins with host Scott Aukerman and co-host J.C. Monahan introducing the day's significant testimonies. The defense presented their final witnesses: Dr. Elizabeth La Posada, a renowned forensic pathologist, and Dr. Andrew Rentschler, a crash reconstruction expert from Arca. These experts aimed to challenge the prosecution's narrative by providing alternative explanations for Officer O'Keefe's injuries.

Key Points from Dr. La Posada's Testimony

Dr. La Posada's testimony was a focal point of the day's proceedings. She meticulously dissected the prosecution's theory that John O'Keefe was fatally injured by Karen Read's SUV.

  • Inconsistent Injury Patterns: At [03:20], La Posada states, "It didn't hit him. It did not hit him. Those injuries are patterned injuries from an animal bite." She argued that the abrasions on O'Keefe's arm were inconsistent with contact from a vehicle's tail light, suggesting instead that an animal, possibly a dog, was responsible.

  • Blunt Force Trauma Analysis: Further emphasizing her findings, at [04:07], she asserts, "No, that project, that rounded thick area would not cause that skin defect multiple times." This indicates that the injuries observed could not have been caused by the alleged impact with the SUV.

  • Alternative Causes of Hemorrhaging: Addressing the prosecution's claims of hypothermia, La Posada proposed that the hemorrhaging could have resulted from over 30,000 chest compressions administered during resuscitation attempts, as she notes at [04:38], "It's around over 30,000 compressions."

Panelist Reactions and Analysis

The panel, consisting of legal analysts Michael Coyne and former prosecutor Margaret McLean, along with courtroom insider Sue O'Connell, provided critical insights into La Posada's testimony.

  • Credibility of Expert Testimony: Michael Coyne highlights the robustness of La Posada's stance, stating at [08:18], "AND I THINK AT THE END OF THE DAY, the judge got it right. We have a coroner pathologist who has multiple years experience...she should be allowed to testify in her opinion, what caused those injuries on the arm and ultimately what caused John O'Keefe's death."

  • Legal Maneuvers: The discussion touches on Judge Kanoni's decision to limit La Posada's testimony regarding dog bites. At [07:50], Monahan elaborates, "Judge Ganoni ultimately ruled that Dr. Lapassada would not be allowed to testify about dog bites." This decision led to a strategic shift, allowing La Posada to speak more broadly about animal bites without specifying dogs.

Legal Analysis: Admissibility of Expert Testimony

A significant portion of the episode is dedicated to analyzing the legal intricacies surrounding the admissibility of expert testimony, particularly relating to animal bites.

  • Daubert Standards: Michael Coyne explains the relevance of the Daubert standards in ensuring that scientific evidence presented in court is both reliable and relevant. At [09:37], he mentions, "Daubert says that if you're going to offer scientific evidence, it has to be scientifically based...and that's the foundation that you have to offer."

  • Judge's Ruling on Expertise: The panel debates whether Judge Kanoni's initial ruling was appropriate. Coyne suggests that while the judge sought clarity on differentiating dog bites from other animal bites, the defense successfully argued for a broader category of animal-related injuries.

Jury Reactions and Engagement

Courtroom insider Sue O'Connell provides an insider's perspective on the jury's demeanor and reactions during the day's testimonies.

  • Juror Engagement: O'Connell observes at [18:00], "They're paying attention. They're taking notes. They're engaged...but when sidebars occur, they are like, they are waiting at a bus terminal." This indicates a mix of attentiveness and frustration among jurors during prolonged legal discussions.

  • Confusion Over Judge's Instructions: A notable moment discussed is when a juror passed a note to the judge, leading to confusion about what needed to be disregarded from their consideration. O'Connell remarks, "What does that mean? I mean, I was sitting there wondering."

Dog Bite Discussion: The Role of Chloe

A recurring theme in the trial has been the potential role of dog bites in causing Officer O'Keefe's injuries. The episode delves into the complexities and risks associated with this line of evidence.

  • Introduction of Chloe: The defense introduced Chloe, the Albert family's German Shepherd, as a potential source of injury. However, inconsistencies arise when it's revealed that Chloe was rehomed and the new owners renamed her Cora, leading to questions about the continuity and relevance of this testimony.

  • Viewer Concerns Addressed: A viewer named Meg raises a pertinent question regarding the absence of Brian Albert, the original owner, in testifying about Chloe. The panel discusses the risk of jurors erroneously attributing the injuries to Chloe without comprehensive evidence, potentially undermining the defense's arguments.

  • Defense's Strategy: Coyne points out that the defense's approach seems to focus on creating reasonable doubt by introducing alternative explanations for the injuries, even if they aren't directly causal to O'Keefe's death.

Conclusion and Next Steps

As the episode wraps up, the panel reflects on the significance of the day's testimonies and what to expect moving forward.

  • Imminent Jury Deliberation: With the defense having presented their final witness, the judge hints at the case being handed over to the jury by Friday or, at the latest, Monday. This marks the beginning of the final phase of deliberation.

  • Anticipation of Rebuttal: The panel anticipates that the prosecution will likely introduce rebuttal witnesses to counter the defense's assertions, particularly addressing the newly presented X-ray evidence of O'Keefe's intact arm bones.

  • Final Thoughts: Michael Coyne emphasizes the critical role of expert credibility and the jury's perception of the evidence's validity, underscoring the case's reliance on scientific testimony.

Notable Quotes

  • Sue O'Connell at [18:14]: "I was sitting there wondering. Or did it all get lodged in here and now?"

  • Michael Coyne at [22:02]: "So, I think a lot of this is still in the air. Are they hoping that all this information in the air creates reasonable doubt? I think so."
