Massachusetts Jury Decision Sequence

Under Model Jury Instructions for Homicide in Massachusetts, jurors must address the sequential queries in order:

Step 1 • Actus Reus & Causation

Did the defendant cause the deaths of the victims?

The Commonwealth must prove unlawful killing beyond a reasonable doubt.

Step 2 • Mens Rea / Degrees of Murder

Malice Aforethought & Premeditation or Extreme Atrocity

First Degree: Deliberate premeditation OR extreme atrocity/cruelty.
Second Degree: Malice aforethought without deliberate premeditation.

Step 3 • Affirmative Defense: Lack of Criminal Responsibility

The Massachusetts McHoul Standard (50/50 Prongs)

Once raised, the Commonwealth bears the burden to prove beyond a reasonable doubt that defendant had:

Substantial capacity to appreciate the criminality/wrongfulness of conduct; AND
Substantial capacity to conform conduct to the requirements of the law.

Step 4 • Unanimity or Stalemate Procedure

Tuey-Rodriguez (Allen Charge) Instruction

If the jury reports deadlocked deliberations, the court may give the Massachusetts Tuey-Rodriguez charge urging jurors to re-examine views without abandoning conscientious convictions.

Psychiatric Evidence & Expert Evaluation Matrix

Contrasting legal evaluation criteria between prosecution and defense psychiatric expert testimony:

Standard	Defense Psychiatric Theory	Prosecution Theory
Mental Disease or Defect	Postpartum psychosis, severe major depressive episode, acute obsessive thoughts.	Medication-induced side effects or anxiety not rising to disabling psychosis.
Cognitive Prong (Wrongfulness)	Delusional state preventing appreciation of the true moral/legal wrongfulness.	Actions (masking intentions, structured timing) suggest awareness of illegality.
Volitional Prong (Conforming Conduct)	Overwhelming command delusions or irresistible psychotic compulsion.	Calculated steps show defendant possessed voluntary agency and self-control.
Legal Burden of Proof	Defense introduces evidence to satisfy threshold of lack of responsibility.	Commonwealth must DISPROVE lack of responsibility beyond reasonable doubt.

Key Statutory Citation: Commonwealth v. McHoul, 352 Mass. 544 (1967); Massachusetts Superior Court Model Jury Instructions on Lack of Criminal Responsibility.
