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
An insanity acquittal is not a prison sentence (civil commitment)
Subject to periodic review
May be released if found no longer dangerous
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
