Karen Read second trial enters it’s 12th day on Thursday. Watch courtroom proceedings live below.

Read, 45, of Mansfield faces charges of second-degree murder, manslaughter while operating a motor vehicle under the influence, and leaving the scene of a collision causing death.

Prosecutors say she struck John O’Keefe, a Boston cop she had dated for two years at the time, with her Lexus SUV and left him to freeze and die on the front lawn of 34 Fairview Road in Canton in the early morning of Jan. 29, 2022.

Yesterday saw testimony from a second digital forensics expert for the prosecution, who testified that a key search for “hos long to die in cold” was made when the person who searched it, Jennifer McCabe, said she searched it.

McCabe testified that she made the search at 6:24 a.m. at Read’s prompting upon finding O’Keefe on that front lawn. The defense says their expert will prove McCabe made the search at 2:27 a.m., indicating she knew O’Keefe’s fate hours before he was allegedly discovered and thus pointing toward a conspiracy.

The first witness called Thursday is Massachusetts State Police Sgt. Yuri Bukhenik, who works as a homicide detective stationed at the Norfolk District Attorney’s office. He was one of the primary investigators in the case.

This is a developing story.
