The essentials

Mistrial declared as jury splits 11-1 on insanity verdict over criminal responsibility.

A mistrial was declared after the jury became deadlocked 11-1, unable to reach consensus on criminal responsibility. The jury foreperson reported that the holdout juror acknowledged reasonable doubt but refused to consider an insanity verdict, instead focusing on the killings themselves rather than the legal question of criminal responsibility.

Deliberations became so heated that alternate jurors could hear arguments from the deliberation room. The foreperson submitted a note to the judge expressing concerns about the holdout juror's approach. The juror rarely examined trial exhibits and rejected a request to have the judge re-explain reasonable doubt.

Jurors also offered post-trial criticism, noting that some jurors criticized the prosecution's harsh presentation lacking character witnesses. Notably, nurses on the jury used medical knowledge to interpret toxicology evidence, contributing to their assessments during deliberations.
