About

Sergeant Yuri Bukhenik of the Massachusetts State Police served as the senior supervisor on the Karen Read investigation, working alongside lead investigator Trooper Michael Proctor. His testimony spans the full arc of the investigation: the initial response on January 29, 2022, multiple evidence searches at 34 Fairview Road in February, interviews with Karen Read and Brian Higgins, and review of surveillance footage from Ring cameras and Canton-area bars. Across fourteen proceedings in both trials, Bukhenik was the prosecution's primary witness for establishing the investigative timeline and chain of custody for physical evidence, while the defense used his testimony to surface what it characterized as systematic investigative failures and conflicts of interest.

Key Points

  • On direct examination, Bukhenik testified that he directed Trooper Proctor to approach Read's Lexus to observe the damaged rear right taillight at the Dighton residence — establishing the first law enforcement observation of the vehicle damage central to the prosecution's theory.
  • Bukhenik testified that surveillance footage documented Read consuming nine drinks across two bars on the night of January 28-29, 2022, and that Ring doorbell video critical to the timeline — including footage of Read showing the taillight damage to Jennifer McCabe and Kerry Roberts — was missing from what Ring Corporation provided.
  • During cross-examination in both trials, defense attorney Jackson demonstrated that the sallyport surveillance video Bukhenik had authenticated on direct examination as 'true and accurate' was in fact mirror-inverted, meaning investigators and jurors had been viewing it backwards — a disclosure that had not been made during direct and that concealed Trooper Proctor's proximity to the damaged taillight during the vehicle seizure.
  • On cross-examination, Jackson asserted a November 4, 2023 date for narrative reports concerning the three February 2022 searches. Bukhenik said that timing was possible, but rejected the suggestion that no documentation existed, identifying contemporaneous evidence-bag documentation of the time, location, person who recovered each item, and a brief description.
  • At the close of Trial 2, Jackson asserted that Trooper Guarino's extraction showed O'Keefe's phone logging 36 steps over about 84 feet and that this placed O'Keefe inside 34 Fairview. After Brennan objected, the court narrowed the question to whether Bukhenik had information about steps logged on the phone; Bukhenik said he did not and later said he was not aware of that data. The exchange did not establish through Bukhenik that the phone movement was O'Keefe's movement or that it placed him inside.
