The second murder trial of Karen Read, a former adjunct professor and financial analyst who is accused of causing the death of her Boston police officer boyfriend, continues Monday with additional witnesses to be called to the stand.

Prosecutors retrying Karen Read in the killing of her boyfriend are laying out a minute-by-minute accounting of what they say happened at the suburban home of a fellow law enforcement officer where John O’Keefe was found unresponsive on a snowy morning three years ago.

Ms. Read’s retrial on charges that she killed her boyfriend, a Boston police officer, has so far largely resembled her first, which ended in a mistrial.
