Overview

  • Canton paramedic Katie McLaughlin testified that Karen Read repeatedly said, 'I hit him,' after discovering John O’Keefe’s body in the snow in January 2022.
  • Forensic scientist Hannah Knowles testified that Read’s blood alcohol content at the time of the incident could have been as high as 0.28%, over three times the legal limit for driving in Massachusetts.
  • Jennifer McCabe, another prosecution witness, also testified last week that Read admitted to hitting O’Keefe, though the defense questioned her credibility and alleged inconsistencies with earlier statements.
  • The defense continues to argue that O’Keefe was killed by other law enforcement officers at the party and that Read is being framed as part of a conspiracy.
  • The retrial follows a 2024 mistrial and features new legal teams and evidence, including video clips of Read’s media interviews used by prosecutors to support their case.
