Judge Denies Mistrial in Karen Read’s Second Murder Retrial

Defense highlights alleged investigator bias to undermine prosecution’s crash reconstruction evidence

Overview

  • Judge Beverly Cannone refused to declare a mistrial after prosecutors questioned defense expert Dr. Marie Russell about the absence of dog DNA on John O’Keefe’s sweatshirt.
  • Dr. Marie Russell testified that scratch marks on O’Keefe’s arm were consistent with a dog attack despite admitting she was unaware of DNA results when forming her opinion.
  • Crash reconstruction expert Matthew DiSogra challenged the prosecution’s clock-synchronization analysis, warning that isolating a single timestamp cannot conclusively link Read’s SUV to O’Keefe’s cellphone movements.
  • Jonathan Diamandis described sexist text messages sent by former lead investigator Michael Proctor, and jurors reviewed messages in which Proctor disparaged Read and discussed premature conclusions.
  • After prosecutors played clips from her televised interviews, Read’s defense opted not to call her to testify, preserving her right to remain silent.
