Testimony in Karen Read’s murder trial continued Thursday. Here’s what happened.

Several first responders have taken the stand this week to testify about what they saw and heard at the scene the morning John O’Keefe died.

On the stand:

• Katie McLaughlin, Canton Fire Department

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

• Francis Walsh, Canton Fire Department
• Matthew Kelly, Canton Fire Department
• Anthony Flematti, Canton Fire Department

1 p.m. update: Firefighter testifies she heard Read say ‘I hit him’

“Visibly distraught” after finding John O’Keefe lying unresponsive in the snow, Karen Read repeatedly stated “I hit him” while first responders tended to her boyfriend, Canton firefighter and paramedic Katie McLaughlin testified Thursday.

“She seemed very upset, very upset,” McLaughlin said of Read.

She said Read was able to provide John O’Keefe’s name and birthday, and possibly answer some initial questions about his medical history. When McLaughlin asked Read whether O’Keefe had suffered any significant trauma, Read allegedly replied, “I hit him.”

“There was a woman standing across from her who I believe at that point said, ‘You’re hysterical. You need to calm down. You’re hysterical,’” McLaughlin said. “[Read] repeated, ‘I hit him.’ And there was a police officer who was in that vicinity kind of with us who replied, ‘You what?’ She repeated it one more time and that officer then signaled to somebody, ‘Get Goode down here,’ which I’m assuming would be the [police] sergeant.”

12:15 p.m. update: Dashcam video appears to show Read screaming at the scene

Canton firefighter Matthew Kelly told the court he heard Karen Read screaming upon his arrival at 34 Fairview Road.

“It was just something like, ‘He’s dead. He’s f—ing dead,’” Kelly testified.

On cross-examination, defense attorney David Yannetti asked Kelly, “It’s fair to say that at no point in time did you ever hear her say, ‘I hit him, I hit him, I hit him,’ correct?”

“Correct,” Kelly replied.

Read’s lawyers played a clip of dashboard camera footage from the scene, and Kelly confirmed he heard someone scream “f—ing dead” in the video.

11:40 a.m. update: Snow reached about halfway up O’Keefe’s ribs, firefighter testifies

Karen Read was “the most distressed on scene” and was attempting to resuscitate John O’Keefe when first responders arrived at 34 Fairview Road on Jan. 29, 2022, acting Canton Fire Lt. Anthony Flematti testified Thursday.

“She was running back and forth between the other female on scene and the body, back and forth, trying to press on his chest, wake him up, talk to him, just to no avail,” Flematti said.

First responders “tried to get any type of information we could from her at that time, but with no luck,” he continued, adding, “The only response that … I was personally given was just, ‘I hit him. I hit him. Oh my god, I hit him.’”

He said he directed Read to another Canton firefighter, Katie McLaughlin, to see if McLaughlin could gather more information about what had happened to O’Keefe.

According to Flematti, there was about 4 to 6 inches of snow around O’Keefe’s body, reaching about halfway up O’Keefe’s ribs. He said the top of O’Keefe’s body was free of snow when he arrived.

Flematti explained that first responders typically check to see if a patient’s body is rigid, or if there’s any lividity where their blood has pooled and caused discoloration in the skin. Because O’Keefe’s limbs were able to be moved and his back was still red, firefighters continued to work on resuscitating him. First responders gave O’Keefe epinephrine multiple times in an attempt to stimulate his heart muscles and vasculature, Flematti explained.

“Both eyes were pretty well swollen shut,” Flematti said of O’Keefe’s injuries, also describing bruising on O’Keefe’s forehead, cuts on his right arm, and swelling in his abdomen.

O’Keefe’s pupils did not respond to light, Flematti added. He testified there was dried blood on the injuries to O’Keefe’s arm, which wasn’t actively bleeding by then.

Defense attorney Alan Jackson noted that Flematti stayed at Good Samaritan Medical Center for some time after dropping off O’Keefe.

“But you never relayed to a single doctor or a single nurse a single word about a woman who said, ‘I hit him,’ did you?” Jackson asked.

“Documentation for us ends at transfer of patient care,” Flematti answered. “As far as my memory, I do remember relaying that information to the doctors and nurses.” Specifically, he said he recalled telling medical staff there was a question of whether O’Keefe had been struck by a car.

Jackson asked whether Flematti has ever testified that he relayed this information, and Flematti replied that he’s never been asked about doing so in a court setting.

Responding to a later question from prosecutor Adam Lally, Flematti said he relayed the information about a possible motor vehicle collision because of Read’s alleged “I hit him” statements and because O’Keefe’s body was found near the street.

“People don’t just lie down in the snow in a blizzard,” Flematti said. “So how he got there we’re not sure, so we’re trying to figure out what happened, but due to the proximity to the roadway, that was our first inclination.”

is back in court Thursday for a third day of witness testimony in her high-profile murder trial.

Acting Canton Fire Lt. Anthony Flematti had just begun his testimony Tuesday afternoon when Judge Beverly Cannone concluded the day’s court proceedings. Thursday’s session will be another half day, running from 9 a.m. to 1 p.m.

Several police and fire department witnesses have taken the stand so far, telling jurors what they saw and heard the morning Boston Police Officer John O’Keefe died.

Read, 44, is accused of backing her SUV into O’Keefe, her boyfriend of two years, and leaving him to die on a snowy lawn in Canton on Jan. 29, 2022. Prosecutors allege Read was driving drunk following a night out and struck O’Keefe while dropping him off at a fellow Boston officer’s home for an afterparty.

However, lawyers for the Mansfield woman say she was framed in an elaborate coverup among witnesses and law enforcement, suggesting O’Keefe was actually beaten inside the home and possibly attacked by the family’s German shepherd.

Throughout cross-examination, defense attorneys have picked apart first responders’ testimony to highlight discrepancies between their initial incident reports, grand jury testimony, and the statements they’ve made in court this week.

On Tuesday, defense attorney Alan Jackson repeatedly pressed Canton firefighter and paramedic Timothy Nuttall on whether O’Keefe’s injuries — specifically, a bump on his forehead and scratches on his arm — were consistent with a physical altercation.

Read has pleaded not guilty to charges of second-degree murder, motor vehicle manslaughter while driving under the influence, and leaving the scene of a collision causing injury and death.

Jurors will take a trip to view the crime scene Friday morning, per an order from Cannone. The media and members of the public are barred from filming, photographing, interviewing, or contacting jurors during court proceedings — including the view — and Cannone has ordered a 100-yard buffer zone between jurors and public attendees.
