Battle of the Experts ARCCA vs Aperture in the Karen Read Trial

​In this episode of Hidden Killers, retired FBI Special Agent Jennifer Coffindaffer joins Tony Brueski to break down the forensic battle at the heart of the Karen Read trial. On one side, you have ARCCA—a nationally respected accident reconstruction firm—offering dramatic simulations and biomechanical assessments. On the other, Aperture’s Shannon Burgess delivers SUV telemetry data that pinpoints a 12:32 AM reverse gear event—coinciding with the last known movement on John O’Keefe’s phone.

But how credible are these experts? We dig into the court revelations about Burgess’s résumé errors and admitted confusion over basic data units—raising real questions about reliability. Meanwhile, ARCCA’s reenactment has been criticized for lacking scientific precision and leaning into visual storytelling rather than hard data.

Coffindaffer analyzes both sides from a federal investigative lens: What’s valid? What’s theater? And what would an FBI-led forensic team have done differently? If you’re confused by the dueling experts, you’re not alone. This is your guide through the noise.
