McLaughlin will finish his testimony Friday morning before jurors take a trip to view the crime scene.

The first week of Karen Read’s high-profile murder trial comes to close Friday with additional witness testimony and a field trip to view the crime scene in Canton.

Friday’s session is expected to pick up with testimony from Canton firefighter and paramedic Katie McLaughlin, who took the stand Thursday to share some of the things she saw and heard as first responders tended to Boston Police Officer John O’Keefe on Jan. 29, 2022 .

Prosecutors allege that earlier that morning, Read, 44, backed her SUV into O’Keefe, her boyfriend of two years, and left him to die in a blizzard. The couple had gone out drinking, and Read is accused of driving drunk and striking O’Keefe while dropping him off at an afterparty held at a fellow Boston police officer’s home.

But lawyers for the Mansfield woman say she was framed, that O’Keefe was actually beaten inside the home and possibly attacked by the family’s German shepherd, and that witnesses and law enforcement engaged in a widespread coverup.

Several first responders have testified they heard Read say “I hit him” after they arrived at 34 Fairview Road on Jan. 29, 2022. On Thursday, McLaughlin and acting Canton Fire Lt. Anthony Flematti both testified that Read uttered the phrase repeatedly as paramedics attempted to ask her questions about O’Keefe.

However, other witnesses who were at the scene that morning say they didn’t hear Read say “I hit him.” While Canton firefighter Matthew Kelly told the court he heard Read screaming upon her arrival, he testified that she said something along the lines of, “He’s dead. He’s f—ing dead.”
