In a Boston murder trial, a second smartphone forensics expert, Jessica Hyde, testified about the digital evidence connected to Jennifer McCabe’s searches regarding the victim, John O’Keefe, after his body was found. Hyde stated McCabe searched for “long to die in the cold” around 6:24 a.m., while the defense argues this happened much earlier, at 2:27 a.m. Hyde clarified that a previous timestamp does not link to the actual search, but instead corresponds with when McCabe opened her browser.
Hyde’s testimony aligned with that of Ian Whiffin, a digital forensics expert. He works with Cellebrite, a company that produces software for mobile data extraction. Notably, some jurors struggled to grasp the technical jargon used during her testimony, which led Philadelphia lawyer David Gelman to criticize the prosecutors. He suggested that they failed to present the information in a manner that was engaging or easy to understand for the jury.
During the proceedings, a recording of Karen Reed’s voicemail to O’Keefe was played, in which she expressed animosity towards him. Reed’s case had previously ended in a hung jury, prompting a retrial. This time, special prosecutor Hank Brennan is leading the case, while defense attorney Robert Alessi cross-examined Hyde, questioning her reliability as a witness based on past trials.
On cross-examination, Hyde noted that police had not followed best practices in securing O’Keefe’s phone calls after they retrieved the device from the scene. The defense maintained its position, asserting that Reed was innocent of the charges against her, including murder and manslaughter. According to prosecutors, Reed had consumed alcohol before striking O’Keefe with her SUV after leaving a bar.
As further evidence was presented, Massachusetts trooper Connor Keefe elaborated on how evidence, such as cell phones and taillight fragments, was collected at the scene. He opened an evidence bag before the jury, revealing unexpected extra pieces. Keefe appraised the jurors on the timeline surrounding the accident, emphasizing the location where the collision taken place.
Testimony is set to resume on Thursday morning, where the court will continue to hear expert analysis and other evidence pertinent to the case.
