Snow, Taillights, and Reasonable Doubt: The Karen Read Murder Trial
In the freezing winter of 2022, Boston Police Officer John O’Keefe was found dead in a snowbank outside a fellow officer’s home. His girlfriend, Karen Read, was accused of killing him with her SUV and leaving him to die. What followed were two high-profile trials — the first ending in a mistrial, the second in a full acquittal — that captured national attention and became a masterclass in the art of creating reasonable doubt.
In this engaging, story-driven CLE, we’ll walk through both trials, analyze the prosecution’s and defense’s theories, compare the two proceedings, and break down the strategies that led to the ultimate not-guilty verdict. Along the way, you’ll gain practical trial tips for defending circumstantial murder cases, managing pretrial publicity, and leveraging jury instructions to your advantage.
Learning Objectives
By the end of this session, participants will be able to:
- Compare and contrast prosecution and defense strategies in the first and second Karen Read trials.
- Identify key evidentiary and procedural differences that contributed to differing outcomes.
- Apply effective techniques for creating reasonable doubt in a circumstantial case.
- Recognize the role of investigative bias and media influence in shaping trial narratives.
- Integrate jury instructions strategically into closing arguments for maximum impact.
Timed Agenda
12:00pm – 12:10pm — Review facts of murder
- Early morning, Canton, MA. John O’Keefe, a respected Boston Police officer, found in the snow outside a fellow officer’s home. Injuries: head trauma, hypothermia.
- Karen Read — a financial analyst, former girlfriend, last known person to see him alive.
- Eyewitness fragments: late-night drop-off, SUV taillight debris, cracked rear light on Read’s car.
- Early decisions in evidence collection (or lack thereof) that will haunt both trials.
12:10pm – 12:40pm — Initial Legal Theories
- The Prosecution’s Theory
- Prosecutor’s circumstantial evidence approach — strengths and vulnerabilities.
- How to keep a chain of circumstantial evidence unbroken (and what happens if a single link breaks).
- Intent issues: murder vs. manslaughter considerations.
- The Defense’s Theory
- O’Keefe was assaulted inside the home or nearby, not struck by Read’s SUV.
- Taillight debris could have been planted or misinterpreted.
- Police officers at the afterparty had motive to close ranks.
- Investigators ignored key evidence that pointed away from Read.
- The “alternate perpetrator” defense — when it’s powerful and when it’s risky.
- Using investigative gaps to your advantage (and avoiding speculation that alienates jurors).
- The tightrope between conspiracy suggestion and credible alternate theory.
12:40pm – 1:00pm — The First Trial (2024) — Mistrial
Review of key witness testimony
- Review of closing statements
- How juror disagreement in a mistrial can foreshadow acquittal (or retrial strategy).
- Media leaks, pretrial publicity, and their role in juror psychology.
- Lessons from first trial mistakes: when to not overcomplicate your narrative.
1:00pm – 1:20pm — The Second Trial (2025) — Acquittal
- Prosecutors streamline case — fewer witnesses, cleaner exhibits.
- Defense sharpens expert testimony — snow temperature, injury timelines, biomechanics of SUV strikes.
- Prosecution’s burden becomes more visible — each link in the circumstantial chain questioned.
- Jury instructions hammer home: if any link fails, the chain is broken.
- Verdict: not guilty on all counts.
Lessons Learned
- How small strategic shifts flipped the outcome.
- The underestimated power of concise, consistent defense messaging.
- Importance of jury instruction emphasis in closing argument.
1:20pm – 1:40pm — Comparing the Two Trials
- Side-by-side differences: witness credibility, expert scope, jury demeanor, press coverage.
- How the defense learned to avoid overreaching and stuck to provable doubts.
- How prosecution’s narrowing case actually made it easier for defense to attack individual links.
1:40pm – 2:00pm — Lessons Learned: Building Reasonable Doubt in a Circumstantial Case
Practical Trial Tips:
- Attack the weakest link early — don’t wait for closing.
- Always give jurors a plausible alternative — not just “maybe it didn’t happen.”
- Use experts as translators — jurors trust explanations more than raw data.
- Exploit contradictions between trials — testimony shifts destroy credibility.
- Make jury instructions your co-counsel — rehearse your closing around the “burden of proof” language.
