A new witness took the stand May 8 after defense attorneys sparred with an expert over the timing of a star witness' Google search in the murder trial of Karen Read.
Read, 45, is accused of hitting her boyfriend, Boston Police Officer John O'Keefe, with her Lexus SUV and leaving him for dead outside the home of a fellow cop in January 2022. Prosecutors say Read deliberately hit O'Keefe, 46, in a drunken rage.

An analysis of the phone of Jennifer McCabe, a friend of the couple who testified for the prosecution, found she Googled how long does it take to die in the cold the day O'Keefe was found. A second expert testified that the search was made after O'Keefe was found unconscious, not before as the defense has suggested.
Read's lawyers say she was framed for O'Keefe's murder. Court ended May 7 with prosecutors playing a clip of Read saying "Jen McCabe, it's me or her. Either I'm going down, Jen, or you are."
The case out of Dedham, Massachusetts has turned into a years-long whodunnit legal saga that has garnered massive intrigue from true-crime fans across the country, spurring an array of podcasts, movies, and television shows. The former financial professor is back in court after a 2024 trial ended in a hung jury.
The first full day of testimony was April 23. Judge Beverly Cannone estimated the trial could last between six and eight weeks and told jurors recently that the proceedings are on or slightly ahead of schedule.
Yuri Bukhenik, a Massachusetts State Police trooper, told jurors what Read said to police and what O'Keefe's body looked like the day he died.
Bukhenik said blood was pooled beneath O'Keefe's head and seeping into the sheets of his hospital bed after his death. Both of O'Keefe's eyes were swollen and discolored and there were small cuts on his face. Bukhenik said there were also cuts and bruises on his right arm, hand and knee.
Bukhenik showed jurors pieces of clothing O'Keefe was wearing the day he died. He said he found it "very significant" that one of O'Keefe's shoes was missing and while he was at the hospital, he began to theorize that O'Keefe had been struck by a car.
"I was suspecting that he was hit out of his shoes," Bukhenik said.
O'Keefe's sneaker was later found at the scene, according to previous testimony.
Bukhenik then went to talk to Read at her parents' home, where he saw that a large piece of the red taillight cover was missing from her SUV. When asked about the damage, Read said, "I don't know how I did it last night."
Read told police that after a night of drinking, she dropped O'Keefe off at 34 Fairview Road. She said she made a three-point turn and left without seeing him go into the house, according to Bukhenik.
When asked how O'Keefe might have sustained his injuries, Read told police O'Keefe had bumped his head two nights before and had asked her about it. Police then seized Read's vehicle and cell phone, Bukhenik said.
Jessica Hyde, a digital forensics examiner, said a tab was opened on Jennifer McCabe's phone at 2:27 a.m. on Jan. 29 and multiple searches were made at some point, including for sporting events, a video of the song It's Raining Men and two crucial, misspelled questions "hos (sic) long to die in the cold" and "how long ti die in cikd (sic)"
Hyde said "hos (sic) long to die in cold" was the final search made in the tab at 6:24 a.m. O'Keefe was found around 6 a.m.
Hyde is the second expert to tell jurors this search was made after 6 a.m. Ian Whiffin, a digital intelligence expert, testified on April 28 that forensic data showed the Google search occurred at about 6:23 a.m.
Read's attorney attempted to poke holes in Hyde's testimony by pointing out differences between her previous testimony, her report and Whiffin's findings.
CourtTV has been covering the case against Read and the criminal investigation since early 2022, when O'Keefe's body was found outside a Canton home.
