Witness Jennifer McCabe is expected to retake the stand when the Karen Read murder trial resumes for its 16th day at 9 a.m.

Read, 44, of Mansfield, faces charges of second-degree murder, motor vehicle manslaughter and leaving the scene of a collision causing the death of O’Keefe, a 16-year Boston Police officer and her boyfriend of about two years when he died at age 46. Prosecutors say that after a night out drinking the pair argued and she killed him by backing her Lexus SUV into him, leaving him to die in the cold during a snowstorm.

McCabe was the only witness during the half-day Tuesday when she was under tense cross-examination following her direct testimony on Friday. There was no court on Monday.

Many expected questions, like a detailed examination of when McCabe’s “ho(w) long to die in cold” Google search was made, are likely to come out today. Defense attorneys in pre-trial hearings and court filings have argued the search was done hours before O’Keefe’s body was found on the lawn, which would implicate McCabe and others in an alleged scheme that framed Read for O’Keefe’s death.

At the end of Tuesday, prosecutor Adam Lally said that the next witnesses on his list are Laura Sullivan and Marietta Sullivan — two people who have not previously been mentioned in testimony — as well as ATF Agent Brian Higgins. Lally said that he didn’t expect to get through all of them on Wednesday.

This is a developing story.
