Defense Demands Mistrial in Karen Read Case Over Dog DNA Evidence

The Karen Read trial took an unexpected turn on June 3, 2025, when the defense dramatically requested a mistrial with prejudice. The defense's motion hinges on the Commonwealth's late introduction of dog DNA evidence, arguing that this evidence was strategically withheld and that the chain of custody was severely compromised. The courtroom drama unfolded with the defense attorney passionately arguing, "This impression that Mr. Brennan is trying to give...that somehow the defense brought this topic up before...is incorrect." The prosecution countered, emphasizing the defense's prior strategic decisions and the potential for significant procedural flaws. The judge's decision on the mistrial motion remains pending, leaving the future of the trial uncertain. The outcome will significantly impact the case's trajectory and raise crucial questions about the handling of evidence in high-profile trials.
