MA Statute (Rule 27 - Verdict) provides doing so requires the consent of the Judge who clearly did not tell the panel she wanted to learn if/when they reached a unanimous verdict on any of the multiple counts filed against KR, and would record these verdicts. IMO, when the Statute puts the discretion on the Court, this does not fall on the attorneys but squarely on the Judge. It certainly didn't fall on the jurors!
For example, pursuant to Rule 27, when there are two or more offenses (or defendants tried together), the jury may, with consent of the judge at any time during its deliberations or be required by the judge to return a verdict or verdicts where a verdict has been reached; and thereafter the jury may in the discretion of the judge resume deliberations.
It doesn't follow that the CW and the Court both want to punish the defendant when they failed to guide and/or inform the panel of the very remedy available-- at the discretion of the Judge.
