## Jury Instructions
### Massachusetts Insanity Defense
Judge Sullivan instructed jury on insanity defense standard
Explained lack of criminal responsibility
Provided guidance on evaluating expert testimony
Outlined elements of the charges
## Verdict — Pending
### As of Aug 31, 2026 — No Verdict
Jury deliberations began Aug 28, 2026; no verdict has been returned
If found not guilty by reason of lack of criminal responsibility (McHoul), the finding would be lack of criminal responsibility due to mental disease/defect, not a finding of innocence
Potential commitment would be civil to a DMH facility (e.g., Tewksbury) — no order has been issued
### Legal Significance (If Applicable)
An insanity acquittal is not a prison sentence (civil commitment)
Subject to periodic review
May be released if found no longer dangerous
## Post-Trial — Pending
### Potential Commitment (No Order as of Aug 31, 2026)
No commitment has been ordered; jury is deliberating
If applicable, commitment would be civil to a DMH facility (e.g., Tewksbury), indefinite, subject to Massachusetts mental health laws
### Civil Lawsuits
Lindsay Clancy filed civil lawsuit against medical providers
Patrick Clancy filed separate civil lawsuit
Both allege medical malpractice
