Day 26 - June 3, 2025

Attorney Alessi moves for a mistrial with prejudice, arguing that prosecutor Brennan intentionally introduced the topic of DNA — specifically the absence of dog DNA on John O'Keefe's clothing — for the first time before the jury during cross-examination of defense expert Dr. Russell. Alessi contends the defense was meticulous about avoiding any mention of DNA and that the prosecution lacked admissible foundation, having strategically chosen not to call their DNA witness in this trial. Brennan responds that the absence of dog DNA goes to the heart of Dr. Russell's opinion about dog-inflicted injuries, that the defense was on notice about rebuttal evidence, and cites specific transcript pages from the December 2024 Lanigan hearing where Alessi himself raised DNA on direct examination. Judge Cannone denies the motion for mistrial, saves the defense's rights, and permits Brennan to continue the line of questioning. A brief sidebar follows regarding foundation requirements for Dr. Walsh's opinion.

Outside the jury's presence, ADA Hank Brennan conducted a brief voir dire of Dr. Marie Russell regarding Dr. John C. Walsh's Deputy Medical Examiner report. Russell confirmed she had received and reviewed the report from the defense and disagreed with Walsh's assessment when forming her opinion that O'Keefe's arm wounds were consistent with a dog bite. Brennan moved to admit the Walsh report, arguing the defense opened the door by vouching for Russell's unique credentials. Defense attorney Robert Alessi objected, citing prior rulings where prosecution witnesses who disregarded materials were not subject to similar document admission. Judge Cannone denied the Commonwealth's request to admit the report, finding Brennan's 'opening the door' argument unpersuasive given the court's prior consistent rulings.

On redirect, defense attorney Robert Alessi addressed two main areas from ADA Brennan's cross-examination. First, Alessi had Dr. Russell examine the actual size of tail light fragments (Exhibit 2011E), establishing they measured approximately 1/16th of an inch or less, and Russell testified these tiny pieces could not have caused the parallel abrasion patterns on O'Keefe's arm. Second, Alessi had Russell read extensively from two peer-reviewed forensic pathology studies — De Munnich (International Journal of Legal Medicine) and Pollock (University of Vienna) — which described dog bite wound patterns including parallel claw marks, puncture wounds, and the significance of overall pattern recognition rather than individual wound analysis. Russell also addressed her differential diagnosis process, testifying that O'Keefe's autopsy and medical records showed no fractures, significant bruising, or internal injuries to the arm or legs — injuries she would expect from a direct vehicle impact at 24 mph.

ADA Hank Brennan conducted recross-examination of defense expert Dr. Marie Russell, systematically using the peer-reviewed articles defense attorney Alessi had her read during redirect to undermine her dog bite opinion. Brennan established that Russell acknowledged there are no accepted standards for identifying dog bites from photographs, and that the articles do not create such standards. He then walked through the specific characteristics of dog bites described in those articles — scissor bites, punctures, lacerations, avulsions, crushing, tearing, and stab-like wound lacerations — obtaining Russell's admission that none of these features are present on O'Keefe's arm. Brennan also challenged Russell's differential diagnosis excluding a vehicle collision, pressing her on having no accident reconstruction training, no knowledge of the collision speed source, and no details about body movement or placement. He concluded by reading from Dr. John C. Walsh's Armed Forces forensic pathology report, which found the abrasions 'highly unlikely to be the result of an animal bite attack' and described them as non-specific abrasions consistent with the body moving over a rough surface.

On re-redirect, defense attorney Robert Alessi addressed three points from ADA Brennan's recross. First, he established that Russell — not Alessi — selected which portions of the articles to highlight, clarifying she lacked highlighting tools while traveling from California. Second, Russell explained that the De Munnich and Pollock articles were cited to support pattern recognition methodology for identifying dog bite wounds, not to require every listed characteristic be present. Third, Alessi read from Dr. John C. Walsh's report, highlighting Walsh's conclusion that O'Keefe's injuries were 'non-specific and may be the result of a variety of different mechanisms' and that the absence of additional information 'prohibits the attribution of injuries' to a specific cause — language favorable to the defense's position that the wounds cannot be definitively attributed to a vehicle strike.

Defense attorney Alan Jackson conducts a focused redirect of Dighton Police Sergeant Nicholas Barros, addressing two lines of attack from Brennan's cross-examination. First, Jackson uses a birthday analogy to distinguish between forgetting incidental details (day of the week) and forgetting significant observations — Barros confirms he clearly remembers the scene, the people, the conversations, and the condition of the tail light. Second, Jackson neutralizes the implication that their pre-testimony hotel meeting was improper by establishing that Jackson has no local office, that no testimony coaching occurred, and that the meeting was limited to logistics and confirming Barros's prior recollection. Jackson also highlights that the Commonwealth never contacted Barros after his Trial 1 testimony and never subpoenaed him for Trial 2, while establishing that Barros was not present at the Canton PD sally port and therefore cannot speak to what happened to the vehicle there. Barros reaffirms that the tail light condition he observed does not match the photograph shown during direct examination.

ADA Hank Brennan asks Sergeant Nicholas Barros two questions on recross. Barros concedes that his memory has changed since his prior testimony, and — over a defense objection that is overruled — agrees that the closeup photograph showing the missing right rear tail light is consistent with what he saw on January 29, 2022. This directly undercuts the defense's central point from direct examination, where Barros had stated the photograph did not match his recollection. Judge Cannone then excuses Barros and dismisses the jury for the day.
