Massachusetts State Police sergeant who documented vehicle testing and scene evidence

Trial 2
108 lines 2 proceedings

About

Zachary Clark, a Massachusetts State Police crime scene services sergeant, testified that he photographed Karen Read’s vehicle during the execution of a search warrant at the Canton Police Department on February 1, 2022. He processed its front passenger compartment for fingerprints but found no usable impressions. He also photographed the snow-covered lawn near the flagpole at 34 Fairview Road and documented brake and acceleration tests performed by Trooper Joe Paul, along with the vehicle’s backup warning display. Under questioning by defense attorney David Yannetti, Clark said he did not know how long Michael Proctor had access to the vehicle before Clark arrived, whether anyone monitored Proctor, or how much access he had. Yannetti also questioned Clark about a July 2023 interview of Colin Albert in which Clark participated. Clark testified that Proctor wrote the interview report, chose its language, and did not give Clark an opportunity to review it before publication. Clark said February 1 was the only date he was called to 34 Fairview Road.
