The Karen Read murder trial will have gone on for a full week by the end of testimony Wednesday.

Read, 44, of Mansfield, faces charges of second-degree murder, motor vehicle manslaughter and leaving the scene of a collision causing the death of John O’Keefe, a 16-year Boston Police officer and her boyfriend of about two years at the time.

So far, the trial has featured on the testimony of first responders with the exception of the first day of proceedings when O’Keefe’s younger brother Paul O’Keefe and Paul O’Keefe’s wife Erin O’Keefe were the first two witnesses,

Canton PD Officer Steven Saraf, the first of the first responders at the scene of 34 Fairview Road a little after 6 a.m. on Jan. 29, 2022, testified that he heard Read say “‘This is all my fault” as she paced over O’Keefe’s body in the heavy snow, “hysterical.”

Several Canton Fire Department paramedics who responded to tend to O’Keefe also testified that Read made incriminating statements, including repeatedly stating “I hit him,” which paramedic Timothy Nuttall was the first to testify to on the second day of trial.

Fellow paramedic Katie McLaughlin backed up that same recollection when she testified, “She said ‘I hit him.’ … She seemed very upset, hysterical I’d say.”

Others either did not recollect what Read said at the scene or remembered her making non-incriminating statements expressing woe, shock, or concern for O’Keefe’s well–being.

Canton Fire Lt. Francis Walsh testified Thursday that Read was “screaming and crying” and repeatedly asking, “Is he alive?”

Paramedic Matthew Kelly testified that he heard Read screaming, “He’s dead. He’s (expletive) dead!”

On Tuesday, jurors saw the broken cocktail glass that police say they found at the scene. They also saw photos of a piece of red plastic prosecutors say is part of the shattered tail light of the Lexus SUV Read allegedly slammed into O’Keefe with.

The trial is expected to go on for six weeks.
