Crash experts keep company on proof of Lexus SUV at murder trial reading Karen


Karen Reed’s defense team The state then aimed to cut down the credibility of the crashed expert by pointing out suspicions of discrepancies between the expenditures and experiments when the state enters 11-hour testimony.

To read He was accused of murder Her then boyfriend, Boston police officer John O’Keefe, attacked the Lexus SUV outside a house party at 34 Fairview Road, attacking him by dying in frigid temperatures shortly after midnight on January 29, 2022.

The state’s expected final witness, Dr. Judson Welcher, a crash-fall reconstructionist at Texas-based Aperture LLC, had confirmed his findings that the Read vehicle allegedly hit O’Keefe.

Karen Read’s SUV reached a “74% throttle” moment before John O’Keefe’s final move.

“[O’Keefe’s injury]coincides with being hit by a Lexus and contacting hard surfaces such as frozen ground,” Welcher told special prosecutor Hank Brennan.

Sometimes evacuate Cross-examination lineWelcher often provided non-answer questions from defense attorney Robert Alessi over revisions to PowerPoint presentations used in the trial of Reading to portray the investigation of the aperture.

“We assume that the trial began around April 22, 2025,” Alessi said. “Did you create an updated presentation before and after (has it started)?”

“I don’t know,” Welcher replied.

Alessi attempted to identify a timeline for whether Welcher may have made changes to the documents and whether the prosecutors communicated with him regarding the changes.

Welcher was eventually tolerated before testifying that he had changed his presentation for the first time on May 13th. The latest changes occurred like “10 minutes ago”.

“Half of that was responding to objections from the defense,” Welcher said. “I had to add all the parts to every place. Then, when I came out here, Mr. Brennan asked me to take a reference to evidence about the statement that I was not permitted to present. So it would have been within the last three days. Then I am now amended that several times today based on the award from the judge.”

However, Welcher testified during cross-examination that any revisions he made to the presentation did not alter the entire document.

“I changed one slide,” Welcher said. “We had 130 slides originally, or something like that. Half of the changes that day was one slide. We added one line to the bottom of the previous slide.”

“So, if it wasn’t important, why did you make it during the trial?” Alessi asked. “Why didn’t you just leave it behind and then discuss it from the point of view of testimony?”

“So it was insignificant and I didn’t have to have it, so I ended up being left behind,” Welcher said. “The way it was presented was exactly the way it was before May 13th. So nothing changed.”

During cross-examination, Welcher revealed that the District Attorney’s Office had previously agreed to pay at least $325,000 for the company’s services and to cover the costs of the Lexus SUV used in the test.

“We’re keeping the (vehicle) until the trial is over,” Welcher said. “(So) we sell it and we’re charging the Commonwealth exactly the price difference.”

Aperture has been paid $44,510 for its previous services, and the state is expected to pay more than $400,000 for about eight months of work, according to Alessi.

“Dr. Welcher was best in the direction, but only on cross-examination,” Jack Lou, a senior court at Massachusetts and law professor at Boston University, told Fox News Digital. “He has not answered the question directly from Mr. Alessi. He may not be intentionally avoiding it, but he is no longer a near perfect example of how expert witnesses should testify.”

O’Keefe’s arm injury was testified during direct inspections, along with being hit by the make and model of Read’s vehicle. The crashed expert pointed out a video showing him portraying the car’s taillights before painting the car’s taillights to mimic the collision.

Alessi created doubt surrounding Welcher’s discovery, and attempted to burn the biomechanics engineer into the methodology behind his experiments surrounding the cause of O’Keefe’s eye injury.

“I’m trying to make that clear,” Welcher said. “I don’t know the exact position of his body at the time of the impact, and I don’t know the exact position on the ground. This is part of the reason why I’m not trying to simulate this accurately because there aren’t enough parameters to do that. So I don’t have that information. It shows the geometry compared to someone at O’Keefe’s height.”

“So there’s no information to do that properly,” Alessi said. “So you can’t rule out that he lacerated an eye from spoilers by your own answer you just gave?”

Welcher doubled his investigation and argued that aperture’s experiment was correct based on the information the company had at the time. Under speed Read car.

“Do you agree that you did a blue paint test on the vehicle at 2 mph?” Alessi asked.

“Of course,” Welcher said.

“Did you do a blue paint test using the vehicle at 20 mph?” Alessi said.

“That’s right,” Welcher said. “I wasn’t planning on hitting a Lexus at 20 mph.”

“The models that follow here are very good and professional,” Lou said. “What you have here is that a very great judge meets a very great lawyer,” he added, “This brings loose, less focused cross-examination. This is going well here because the witnesses are very unavoidable.”
