The Karen Read murder trial is set to begin its eighth day of testimony at 9 a.m. in Norfolk Superior Court in Dedham.

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 when he died at age 46.

The majority of testimony in the trial so far has been devoted to the Canton first responders who arrived to tend to O’Keefe at around 6 a.m. and who performed the initial crime scene investigation of the scene on the left side of the front yard of 34 Fairview Road in Canton. Six Canton Police officers and eight Canton Fire paramedics testified over the first six days of the trial.

After Wednesday, which marked a full week of testimony in the trial, prosecutor Adam Lally had called 22 witnesses.

Jurors on Wednesday heard from several people who were involved in O’Keefe’s last night out, Jan. 28 into Jan. 29, 2022. O’Keefe friends Curt Roberts and Michael Camerano went out for drinks with O’Keefe at C.F. McCarthy’s bar in central Canton, a gathering Read would join later.

By 11 p.m., Read and O’Keefe would go across the street to the Waterfall Bar and Grill to meet up with others, including Nicholas and Karina Kolokithas, who each testified Wednesday, to continue their night out.

The party stayed together until bartender Rebecca Trayers started closing up at around 12:10 or 12:15 a.m. Trayers testified that the Waterfall closes up based on customer volume but would never do last call later than 12:45 a.m.

This is a developing story.
