A second forensic phone expert of smartphones testified on Wednesday at the Karen Read trial that Jennifer McCabe's Google search on hypothermia occurred after the remains of John O'Keefe were found, not before, as the defense has argued.
Jessica Hyde testified that she could say with scientific certainty that McCabe used her iPhone to look for the phrase “hos (sic) yearning to die cold” at 6:24 am
The affirmation of the defense that the search occurred at 2:27 AM, hours before the researchers say read, McCabe and Kerry Roberts found O'Keefe dead in the snow in 34 FairView Road, is incorrect, he testified. The previous time brand has no connection with the search, but in reality it is assigned at the time when McCabe opened the browser tab on his phone.
This testimony supported the previous testimony of Ian Whiffin, a digital forensic expert from the Cellebrite firm, which manufactures some of the software and hardware that researchers use to search for information about phones and other devices.

Hyde testified using specific terms: “Hexadecimal editors”, “hash values” and database files, dating technical details on how the phone data is extracted, preserved and interpreted. Even inexperienced analysts may have trouble making sense of things, he testified.
David Gelman, a defense lawyer of the Philadelphia area who has been following the case, questioned the prosecutor's decision to have an expert witness about said technical testimony to take the position before the noon break.
“For an expert, you want them to make sense for a 5 -year -old boy,” he told Fox News Digital. “They failed today. He added that it was an incredibly boring issue, I bet that jury members were only looking at the clock all the time thinking what they will order for lunch.”

After lunch, defense lawyer Robert Alessi handled the interrogation, mentioning the same technical terms and roasting Hyde about his testimony in the first Read trial, of which he was not part.
The trial last year ended with a dead jury, which led the State to bring the special prosecutor Hank Brennan to try again.
Without the jury present, Alessi asked the Court for permission to refer to a recent case of Maryland who said he showed that Hyde was an unreliable witness. Judge Beverly Cannone put on the side of the Brennan team and said she could not mention the judge's decision in that case, but she said that he would be free to interrogate Hyde in the methodology she used to make her findings.

Under interrogation, he testified that O'Kefe's phone was not insured aligned with established “best practices” after the police recovered him from the scene.
She faced Alessi, often using the same technical terms that may have alienated the jury in a direct exam, Gelman said.

“The jurors don't want to sit for days and days,” he said. “They want to enter the flesh and potatoes.”
Read declared innocent of positions of murder, homicide and fleeing from the scene. She could face life imprisonment if she is convicted of the main position.
Massachusetts prosecutors claim that he supported his SUV Lexus in and fatally hit O'Keefe before driving after a night drinking in Canton, a suburb of Boston.

Previously in Wednesday's procedure, Massachusetts state soldier, Connor Keefe, took the position to discuss how he collected evidence in the case, including McCabe and Roberts phones, as well as broken pieces of a rear light and the O'Keefe sports shoe from the crime scene.
At one point, he opened an evidence in front of the jury, and had three pieces of broken plastic inside, not the two expected.

“Do you know if the other piece on the bag is a piece that broke?” Brennan asked. “Do you know how that came there?”

“I don't,” Keefe said.
Brennan asked that the pieces be transferred to evidence, but after an objection of the Read defense, the court told Keefe to place the third piece in a separate evidence bag.

But Keefe's testimony helped prosecutors establish a firm timeline when and where the police found fragments of broken rear lights: on snow -covered streets in front of 34 FairView Road, where O'Keefe and Read had been seen the night before.
