Expert Witness Testimony Sheds Light on Karen Read Trial

The Karen Read trial took another turn with the testimony of expert witness Judson Welcher. Welcher, a vehicle data analyst, presented key findings from his examination of the vehicles involved in the incident. His analysis focused on data from two systems: Techstream and the Pre-Collision System (PCS). "The Techstream data is crucial," Welcher stated, "because it provides information on things like excessive acceleration or rapid steering inputs that can help reconstruct the events." Welcher's testimony included detailed analysis of damage to the vehicles, supported by multiple photographs and diagrams. He explained how he independently downloaded and analyzed the data, ensuring its accuracy. This meticulous approach is crucial for the court's understanding of the accident reconstruction. The case continues to unfold, with the expert's testimony providing vital insights into the sequence of events.
