EXPERT: Body Position, Time Markers & Damage Prove Karen Read's SUV Hit John O'Keefe
In this critical episode, we unpack the
most damning forensic testimony yet in the Karen Read trial—straight from the prosecution’s final witness,
Dr. Judson Welcher, a biomechanical engineer and accident reconstructionist.
Welcher testified that
John O’Keefe’s injuries were “consistent with being struck and dragged” by Karen Read’s SUV, based on an exhaustive analysis of vehicle event data, scene evidence, and physical injury patterns. Using a matching Lexus RX350 and crash test dummies, Welcher simulated the scene and determined that Read’s SUV reversed
53 feet at 74% throttle—without braking.
His conclusion? The SUV's reverse path “
lines up with fatal contact,” and the injuries “
match a collision with a human body,” specifically one standing near the right rear corner of the car. He also cited damage to the vehicle and the pattern of blood and debris as “highly consistent” with a reverse impact.
