About

Sergeant Zachary Clark is a Massachusetts State Police crime scene technician assigned to the Norfolk CPAC unit under Lt. Brian Tully. He was called to document Karen Read's vehicle at Canton Police Department and the scene at 34 Fairview Road on February 1, 2022, the day after John O'Keefe's body was discovered. His testimony covers fingerprint processing, snow and lawn conditions, vehicle documentation, and reconstruction testing conducted that day. On cross, he was questioned about investigative gaps, including Michael Proctor's unsupervised access to Read's vehicle and the delayed interview of Colin Albert.

Key Points

  • Clark testified that fingerprint processing of the front passenger compartment of Read's vehicle yielded no usable impressions.
  • Clark described the condition of the 34 Fairview Road lawn on February 1, noting that while one area appeared cleared and heavily trodden by footwear and tires, significant snow remained — testimony relevant to the scene where O'Keefe's body had been found.
  • Under cross-examination, Clark testified that he was not called to 34 Fairview Road on February 8, 10, 11, or 18; February 1 was the only date he was called there.
  • Clark testified that he was advised upon arrival that John O'Keefe had been found mortally wounded on Brian Albert's lawn.
  • Clark testified that he did not ask Proctor why the Colin Albert interview occurred about a year and a half after the incident, that Proctor wrote the report, and that Clark did not review it before it was published.
