Overview

  • Prosecutors presented recordings of Karen Read's media interviews, where she speculated about possibly hitting John O’Keefe with her vehicle, as evidence against her.
  • Key witness Jennifer McCabe testified that Read admitted to hitting O’Keefe, though the defense challenged inconsistencies in her statements to a grand jury.
  • Forensic scientist Hannah Knowles testified that Read’s blood alcohol content at the time of the incident could have been between 0.14% and 0.28%, well above the legal driving limit.
  • The defense continues to allege a conspiracy involving law enforcement, focusing on the credibility of fired investigator Michael Proctor, who was dismissed for misconduct.
  • Jurors, who recently toured the crime scene, are expected to hear testimony daily this week as the trial progresses in Norfolk Superior Court.
