Karen Read retrial: Biggest takeaways from week 6 as prosecution rests its case

Karen Read retrial: Biggest takeaways from week 6 as prosecution rests its case

Yahoo30-05-2025

The prosecution rested this week in the Karen Read retrial after calling their last witness, a crash reconstruction expert who testified about his opinions whether John O'Keefe's injuries were consistent with being struck by an SUV.
The prosecution's theory is that Read struck O'Keefe in a fit of rage outside of 34 Fairview Road in Canton in January 2022 and left him incapacitated to die in the snow.
Judson Welcher, an accident reconstructionist and biomechanical engineer, spent three days testifying about his analysis of Read's Lexus and injuries to O'Keefe.
Welcher testified that his opinion is that the damage to Read's SUV and the evidence in the case was 'consistent with a collision' with O'Keefe. He said that data from her SUV shows she drove in reverse at more than 20 mph outside of the Canton home where his body was found on Jan. 29, 2022.
He also said that the car driving faster than 8 mph and hitting an arm in a sideswipe could've cracked the taillight.
Then prosecutors used Read's own words to cap off their presentation of their case.
Special Prosecutor Hank Brennan has woven interview clips of Read throughout the trial, and he saved one for the end.
Here are the biggest takeaways from the week:
At the end of Tuesday's testimony, Brennan asked a pointed question about whether Welcher believed, based on his analysis of the evidence, that Read's Lexus collided with O'Keefe around 12:32 a.m. on Jan. 29, 2022.
'Yes, based on the totality of evidence ... that is what happened,' Welcher said.
The defense objected to the question, and the judge ultimately struck the statement from the record. The question then set off a debate between lawyers, but jurors heard Welcher's answer.
Welcher had gone through the day explaining how he derived his opinion. 'Red marks' surrounded the broken cocktail glass in the snow at the scene.
He had played videos of tests he conducted using an 'exemplar' Lexus, another way of saying he had bought the same Lexus model that Read had driven that night.
In one test, the Lexus backed up at 2 mph and struck his right arm, bent and holding a cocktail glass. Blue paint on the taillight transferred onto his arm and left a large mark. When compared side by side with photos of O'Keefe's injuries, they were similar in coverage area.
During cross-examination, Welcher said he did not use a crash dummy because he would only have one or two 'shots at it' before they damaged the car.
'Pedestrian impacts are so sensitive to initial angles,' he said. 'I was not going to hit myself with the Lexus at 20 mph.'
Welcher also pointed out that there was a bruise on O'Keefe's right knee approximately at the height of the bumper of Read's SUV. He said the cuts on his arm were consistent with the 'geometry and orientation' of the right taillight.
Still, he admitted that a lot of information was still unknown about the physics of the crash.
'We don't know the exact point of impact,' Welcher said. 'We don't have absolute information to say exactly where he was.'
Based on the car's data, however, Welcher said that Read's SUV went three quarters 'full throttle' in reverse on Jan. 29, 2022, at around 12:30 a.m. and reached about 23 mph and traveled a total of 87 feet in reverse.
A large part of Welcher's testimony involved attempting to dispel a theory put forward by the defense last trial.
The issue of when Read cracked her taillight is highly contested. Her lawyers have pointed to a Ring video recorded by a security camera above O'Keefe's garage as evidence that she could've cracked it on the morning of Jan. 29, 2022, before she found O'Keefe.
Neama Rahmani, an attorney and former federal prosecutor based in Los Angeles, said Welcher's testimony was useful for prosecutors in combatting one of the defense's big arguments.
'There was also important testimony about the broken taillight and how the broken taillight was consistent with Read hitting John O'Keefe as a pedestrian, and that it was not consistent with an accident with John O'Keefe's vehicle,' said Rahmani, who's followed both trials.
In one video from Jan. 29, 2022, before she found O'Keefe's body, Read backs up and makes contact with O'Keefe's Chevrolet Traverse. Central to the prosecution's theory of the case is that Read backed up her SUV and struck O'Keefe, smashing the taillight on his arm in the process.
'Obviously, the defense is arguing that the taillight was broken in another incident with O'Keefe's car or it was broken when law enforcement impounded the vehicle and towed it in the blizzard,' Rahmani said.
Welcher's presentation, using a PowerPoint, explaining how the company he works for, Aperture, created digital 3D models of both vehicles using laser scanners along with videos. From the videos and laser scans, Welcher said they figured out 'the exact position of the vehicles when that Lexus stopped … and the exact contact.'
'The only evidence of contact is nowhere near the upper taillight,' Welcher said. Using a photograph of O'Keefe's Traverse, he showed that only a scuff mark remained from when Read's SUV made contact well below the taillight.
He said that Read's SUV drove 1 mph or less during the impact with O'Keefe's car. 'That impact did not break or crack that taillight,' Welcher said.
A feature of this retrial is the prosecution's use of video clips of Read's various media interviews in recent years. None of the videos were played in the first trial.
Brennan, who was hired specifically to try the Read case, has woven video clips in between witness testimony.
'These videos are really hurtful,' Jack Lu, a retired superior court judge, said in an interview last week. After a collection of videos was played last week, Lu said the videos 'alone might be enough to convict the defendant.'
After Welcher, the prosecution's final witness, stepped off the stand on Thursday, Brennan played one final clip.
Here is the full quote Read said in the clip:
So I thought, 'Could I have run him over?' Did he try to get me as I was leaving and I didn't know it. I mean, I've always got the music blasting. It's snowing. I got the wipers going, the heater blasting. Did he — did he come in the back of my car and I hit him in the knee and he's drunk and passed out and asphyxiated or something. And then I hired David Yannetti, I asked him those questions. 'The night of January 29, David, what if, I don't know, what if I ran his foot over, or what if I clipped him in the knee and he passed out and or went to care for himself and threw up or passed out.' And David [said] 'Yeah, then you have some element of culpability.'
As the prosecution wound down its case in chief, Read told reporters she would put on a fuller and deeper defense during the retrial than she did at her first trial. On Friday, that began with Matthew DiSogra taking the stand.
DiSogra is the director of engineering for the Event Data Recorder lab at Delta V and is an expert in vehicle data. His primary role for the defense was not to counter Welcher's testimony, but to offer a different interpretation of the data taken from Read's SUV.
While DiSogra relied on the testing of Welcher's Aperture colleague, Shanon Burgess, he came to a different conclusion. DiSogra told the jury that all the clock variances identified by Burgess created 30 possibilities for when exactly the techstream event identified as a 'backing maneuver' happened relative to the last time O'Keefe locked his phone.
It's critical for the prosecution's case that the phone was locked before the 'backing maneuver' ended, because they claim that maneuver is when Read hit O'Keefe with her car. DiSogra explained that of those 30 possibilities, just three showed the phone lock occurring before the end of the event.
Since DiSogra was called by the defense, Brennan got his first chance to cross-examine a witness. Jurors saw a different side of the prosecutor, whose experience as a criminal defense attorney was evident during the questioning.
Brennan came out swinging.
'Are you trying to offer an opinion suggesting Ms. Read's Lexus never hit John O'Keefe on Jan. 29, 2022?' he asked. 'Is that your opinion?'
The opening question set the stage for what was a thorough cross-examination of DiSogra, during which Breannan sought to undermine the accuracy of some of his conclusions. But Alan Jackson, one of Read's lawyers, noted on redirect that all of DiSogra's conclusions were based on the data from Aperture.
The defense will call its next witness when the trial resumes at 9 a.m. Monday.

Brian Albert, Jennifer McCabe, more witnesses speak out after Karen Read verdict

In the hours since Karen Read was found not guilty of killing her Boston police officer boyfriend, John O'Keefe, several key witnesses from both trials have broken their silence on the verdict. Michael Proctor, the former Massachusetts State Police lead investigator on the case, who testified in the first trial and was later fired for misconduct stemming from the case, spoke out in interviews on ABC's "20/20" and NBC's "Dateline" that aired on June 18 and 19, respectively. A group of O'Keefe's friends, including Brian and Nicole Albert and Jennifer and Matt McCabe, also shared their thoughts in an interview with ABC News that aired on June 20. The group earlier called the verdict "a devastating miscarriage of justice" in a statement released to USA TODAY. Both Proctor and the Albert and McCabe families were at the center of the theory presented by Read's defense team about a possible police cover-up in O'Keefe's death. They have consistently denied the allegations. A Massachusetts jury on June 18 found Read not guilty of second-degree murder and leaving the scene of a collision resulting in death. She was found guilty of operating a vehicle under the influence and sentenced to one year of probation. Karen Read timeline Key dates in John O' Keefe murder case Brian Albert says he 'would have taken a bullet' for John O'Keefe In an interview with ABC News that aired on June 20, Brian Albert, a retired Boston police officer who owned the home where O'Keefe's body was found on the morning of Jan. 29, 2022, said he and his family "did the civic duty" in this case. "The criminal justice system has let us down at every turn, and yesterday was the final letdown," he said. Brian Albert also said the theories that he was involved in O'Keefe's death are "preposterous and silly." He responded to lingering questions about why he did not go outside on the morning O'Keefe's body was found, calling it "ridiculous." "I would have taken a bullet for John O'Keefe because he was a fellow cop," Brian Albert said. During the interview, Jennifer McCabe, who was with Read when O'Keefe's body was found, also spoke about the "hos (sic) long to die in cold" Google search she made that became a contentious piece of evidence in both trials. She has maintained that she made the search because Read asked her to after they found O'Keefe's body, while the defense alleged she made the search hours before he was found. "Doesn't matter how much I say about it, people will not believe it," she said. Michael Proctor says crude texts 'don't define me as a person' Proctor's personal text messages, many of which expressed crude comments about Read, came under scrutiny during the first trial. He was later fired for misconduct stemming from the case and broke his silence in a series of interviews after Read's verdict was announced, after he was not invited to take the stand in her second trial. He said in an interview with ABC News that he developed negative feelings toward Read "as the case went on." "When you have a fellow police officer around my age, two kids of his own, it generates emotion," he said. "And I expressed those emotions in a negative way, which I shouldn't've." Proctor added, "They are what they are, they don't define me as a person." In an interview on NBC's "Dateline," Proctor laughed at the theory that he was involved in a possible cover-up. "I laugh because it's such a ridiculous accusation," he said. "There's not one piece of evidence or fact to support that." Melina Khan is a national trending reporter for USA TODAY.
