Jurors in the murder trial of Karen Read returned to the courtroom Monday morning, where they are expected to face a full day of testimony with extended hours.

They have been on break since last week, when they heard from medical experts about Read’s level of intoxication the morning John O’Keefe was found dead and from O’Keefe’s niece and nephew who testified they heard frequent arguments between the two.

Watch the Karen Read trial live on nbcboston.com, NECN, NBC Boston streaming platforms (including Roku, Peacock and Samsung TV) and NBC10 Boston’s YouTube page. Every night of the trial at 7 p.m., come back for analysis and more.

Read is accused of hitting O’Keefe with her SUV and leaving him to die on the lawn of 34 Fairview Road in Canton, Massachusetts. Her defense says she’s being framed.

After O’Keefe’s body was found, Read began acting erratically, according to testimony, which led to her being admitted to Good Samaritan Medical Center.

Blood work done there revealed she had a .081 blood alcohol concentration around 9 a.m. That’s slightly above the legal driving limit.

John O’Keefe’s niece and nephew, both minors, testified off-camera in the murder trial against Karen Read.

However, a forensic toxicologist says if Read had her last drink at 12:45 a.m., her BAC around the time O’Keefe was hit would have been 0.13with a maximum of 0.29.

“It’s just so that encompass essentially anybody within the general population, that they would be somewhere in between that lower limit and that upper limit,” said Nicholas Roberts, former toxicology unit employee at Massachusetts State Police crime lab.

Monday will be a full day of testimony with a shortened lunch break but there is no court Tuesday. Wednesday will be a full day, Thursday a half day and then no court on Friday.

Mass. State Police Lt. Kevin O’Hara testifies

Monday began with testimony from Massachusetts State Police Lt. Kevin O’Hara. He is the team commander for the state police Special Emergency Response Team, or SERT.

On Jan. 29, 2022, the day of O’Keefe’s death, he said he was contacted around 2:30 p.m. by Lt. Brian Tully, supervisor for the Norfolk County District Attorney’s state police detective unit.

He said Tully told him he was conducting a death investigation in Canton and was looking for assistance with an evidence search. O’Hara told Tully members of the SERT team would be able to respond but it could take some time due to the blizzard-like weather conditions at the time.

O’Hara said it was about 3:45 p.m. when he told Tully his team was cleared to respond to Canton. The team members were told to bring shovels, brooms and rakes. O’Hara said he arrived at 34 Fairview Road at 4:56 p.m. Six other members of the SERT team responded along with him.

Once everyone was on scene, the team set up a grid search around where Karen Read’s vehicle was believed to have been parked in front of the Albert home the night before. He said Tully told them O’Keefe had been struck by a vehicle and they should be looking for pieces of broken taillight and possibly O’Keefe’s sneaker. O’Hara said it was already dark out by the time their search began.

After they found several pieces of taillight, O’Hara said he asked for a photo of the vehicle to see how large a section of taillight had broken. But Tully said the vehicle was being towed back to the Canton Police Department.

The taillight pieces were found on the street in between the flagpole and fire hydrant in front of the home, he said. About six or seven pieces in all were located that day. He said they also found a sneaker in the same general location.

The entire search was wrapped up around 6:15 p.m., O’Hara said. He said he told Tully that the team could return during daylight hours to continue their search.

Assistant District Attorney Adam Lally then showed the jury a series of photos of the snowy yard at 34 Fairview Road displaying where the pieces of taillight and the sneaker were found and members of the SERT team conducting their search.

Shortly after 10 a.m., defense attorney David Yannetti began cross-examining O’Hara. Yannetti started by pointing out that the scene had not been secured and had been left open to the public in the hours before the SERT team arrived.

Yannetti also got O’Hara to confirm that it was dark by the time their search began, and Tully advised them of the area they should search.

He also asked O’Hara about a section of his report where he wrote that O’Keefe had been hit and dragged by a vehicle around 12:30 a.m.
