Karen Read Trial Day 21 - Reasonable Doubt Is Gone, Data Shows Karen's SUV Struck John O'Keefe

In today's explosive courtroom session in the Karen Read trial, we dive deep into the forensic testimony of Dr. Judson Welcher—an accident reconstruction expert whose analysis may be the most critical evidence presented so far. At the center of it all: vehicle data showing Karen Read’s Lexus SUV hitting 74% throttle in reverse, accelerating backward at nearly 24 mph outside 34 Fairview Road—the exact time prosecutors allege she struck Boston Police Officer John O’Keefe and left him to die in the snow.

Welcher didn’t just analyze the black box data—he recreated the scenario. Wearing similar clothing and holding a glass like the one O’Keefe had that night, he demonstrated how red paint from a Lexus taillight transferred exactly to the spot where O’Keefe had a deep arm laceration. He matched that with hip and head injuries, dismantling theories of a dog attack or indoor altercation. His conclusion? The SUV’s motion and O’Keefe’s injuries aligned with a sideswipe-style impact.

But the day didn’t stop at science. The defense launched a counterattack, filing new witnesses to authenticate hostile texts from former lead investigator Michael Proctor—texts like “hopefully she kills herself.” They argued this shows investigative bias. Meanwhile, they fought to keep Welcher from stating outright that a collision occurred, calling it jury overreach. Judge Cannone deferred a ruling.

This video breaks down the full day of courtroom drama, forensic testimony, legal chess, and how this moment could turn the entire trial.
