The first trial ended without a verdict
Clancy’s trial lasted more than six weeks.
After the evidence was presented, the case went to the jury. Jurors deliberated for days but ultimately could not reach the unanimous decision required for a verdict.
On September 4, Judge William Sullivan declared a mistrial.
Reports indicated that the 12-member jury was divided, with 11 jurors reportedly favoring an insanity-based acquittal and one juror refusing to agree. The precise legal implications of that disagreement became an important part of the arguments that followed.
A mistrial is not the same thing as an acquittal.
That point is especially important when discussing the current status of the case.
Because the jury did not reach a verdict, Clancy was not found guilty. But she was also not found not guilty.
The criminal charges therefore remain unresolved, and prosecutors can potentially seek another trial, subject to the court’s consideration of the legal motions now before it.
Why did the defense return to court?
Following the mistrial, Clancy’s lawyers filed motions seeking to prevent another trial.
One argument involves the constitutional protection against double jeopardy.
The defense contends that the circumstances surrounding the mistrial were unusual and that Judge Sullivan should have done more to investigate the conduct of the juror who reportedly remained opposed to an insanity-based acquittal.
The defense has argued that the juror may have failed to follow the judge’s instructions concerning reasonable doubt and that the court should have investigated whether the juror could continue participating in deliberations.
The defense subsequently argued that these circumstances should prevent prosecutors from trying Clancy again.
That argument is being contested, and it is ultimately for the court to determine whether the legal requirements for such relief have been met.
A major change in the defense strategy
Another significant development emerged during the September 29 hearing.
During the original trial, Clancy’s defense largely accepted that she was responsible for the deaths while arguing that postpartum psychosis meant she should not be held criminally responsible.
After the mistrial, her lawyers began advancing a different argument.
Defense attorney Kevin Reddington argued that prosecutors had not actually presented enough evidence to establish that Clancy committed the killings.
