Reporters shuttle between the two courtrooms, trying to keep tabs on a murder trial in Courtroom 906 and a political corruption case next door in Courtroom 907. The lawyers from 907 chat with the lawyers from 906 during recesses. Court officers in 906 want to know what’s going on in 907.

In a coincidence of courthouse scheduling, two of the most closely watched criminal trials in Massachusetts are unfolding in adjacent courtrooms on the ninth floor of Suffolk Superior Court.
