Judson Welcher

Judson Welcher is a forensic engineer and accident reconstructionist with over 30 years of experience and ACTAR accreditation, hired by the Commonwealth through Aperture LLC to analyze the physical evidence in the death of John O'Keefe. His testimony spanned three days across Trial 2 Days 21–23 and covered vehicle data analysis, photogrammetric reconstruction of Ring doorbell footage, pedestrian impact biomechanics, and tail light damage assessment. He concluded that the damage to Read's Lexus tail light and O'Keefe's arm injuries were consistent with a collision at speeds above approximately 8 miles per hour, and that a backward fall after such a strike could account for O'Keefe's fatal head injuries.
