Part of Canton Police Department
The Canton PD sally port — the secured garage bay where police vehicles and seized vehicles are processed — held Karen Read's Lexus SUV from the morning of January 29 to February 1, 2022, when State Police executed a search warrant.[1] During those three days, Officer Paul Gallagher conceded, the sally port was accessible to "the entire department" — roughly forty-five Canton PD personnel.[2] The sally port became the physical stage for the defense's evidence-tampering theory, and two features of its surveillance record drove days of courtroom argument.
First, the sally port camera recorded a mirrored, left-right inverted image on January 29. The defense argued the inversion was never disclosed during direct examination;[3] Sgt. Yuri Bukhenik later testified the camera "had been recording that way prior to January 29th."[4] Asked directly whether he or Trooper Proctor had touched the tail-light area while the vehicle was in the sally port, Bukhenik answered, "We absolutely did not."[5] Second, a 42-minute gap exists in the video of Read's vehicle's arrival — the only window in which the tail light's condition at delivery could have been documented.[6] A 2023 statement by Canton dispatcher Kelly Dever describing Higgins and Berkowitz in the sally port added a further point of defense focus.[7]
“I would say the entire department.”
— Paul Gallagher
Gallagher concedes that all ~45 Canton PD personnel had access to the sallyport where Read's SUV sat for three days before state police processing.
“So police officers are issued a — looks like a credit card, I have it in my wallet — um, anytime I enter or leave the police department, the exterior doors going out the back, there's a key scan you put up to it to unlock the door to come in. When you leave you don't have to scan, but if you need to go into the booking area you have to scan yourself in and out, and to get out of the sally ports you have to scan in and out.”
— Sean Goode
Goode described scans for exterior entry and selected booking-area and sallyport movements, while qualifying that exterior exit did not require a scan.
“I personally do not have any data that would indicate where those items of evidence were prior to them being accepted into the lab.”
— Maureen Hartnett
Hartnett testified that she personally lacked data indicating where the items were before lab acceptance; she also agreed that non-sallyport items discussed were submitted March 14 or later.
“And yesterday, during the entirety of your questioning by Mr. Lally, not once did you mention that this video is actually completely inverted?”
— Alan Jackson
Highlights that the prosecution presented a mirrored sallyport video without disclosing the inversion, potentially misleading the jury about which side of the vehicle was shown.
“Outside of it being a mirror image of itself, it accurately depicts any activity or action in the sallyport.”
— Yuri Bukhenik
Concedes the inversion while maintaining the video's substantive accuracy
“We absolutely did not.”
— Yuri Bukhenik
Emphatic denial that he or Trooper Proctor touched or manipulated the taillight area while the vehicle was in the sallyport
“It came from the Canton Police Department.”
— Yuri Bukhenik
Bukhenik identified the Canton Police Department as the entity from which the sallyport video came. He testified that, as advised by Detective Lieutenant Tully, Canton Police had recused themselves from interviews; the judge sustained objections to questions proposing a reason for that recusal.
“I looked into that matter. It produced the fact that it had been recording that way prior to January 29th.”
— Yuri Bukhenik
Establishes the sallyport camera inversion was a pre-existing condition, countering the defense's manipulation theory
“Given factual information that makes it so I know I did not. So the answer is no.”
— Kelly Dever
Dever's current position that her Sallyport observation was a false memory, contradicting her 2023 interview statement.
“Did you tell those law enforcement agents on August 9th, 2023 that you saw Brian Higgins and Chief Berkowitz go into the Sallyport together and alone with the SUV for a wildly long time?”
— Alan Jackson
The core prior statement — placing Higgins and Berkowitz alone with the evidence vehicle for an extended period.
“If you agreed with that statement here on the witness stand, you would be implicating two officers as having been in the Sallyport weirdly for a wildly long time with the SUV, implicating not one but two fellow officers. Correct. That's what you would be doing.”
— Alan Jackson
Jackson makes explicit the career cost of maintaining her original statement — implicating Higgins and Berkowitz.
“It's not in there.”
— Nicholas Barros
After reviewing his Trial 1 transcript, Barros concedes he never actually distinguished the sally port photograph from his on-site observations — contradicting his confident testimony moments earlier that he had.
“I know what I saw and that wasn't it.”
— Nicholas Barros
Despite conceding memory difficulties, Barros pushes back with conviction that the sally port photo differs from his observation — showing the limits of Brennan's impeachment.
The primary Canton PD sallyport interior surveillance recording capturing Read's Lexus SUV arriving on January 29, 2022. The recording as originally provided by Canton PD was mirror-inverted; a corrected (non-inverted) version was later produced and introduced by the defense. The footage shows Trooper Proctor's movements in the sallyport bay, including activity near the right rear taillight area of the vehicle.

Sallyport surveillance footage from the camera facing the right rear taillight area of Read's SUV on January 29, 2022. The video shows a timestamp jump from approximately 5:07:10–5:07:12 to 5:50:47 p.m., an interval of about 43 minutes 37 seconds. The gap begins roughly 22 minutes before the SUV arrived at Canton PD and continues into the initial period after arrival; testimony established that referenced activity did not appear in this feed but did not establish why the interval is missing.
