Summary
The Massachusetts Supreme Judicial Court reviewed Emmanuel Okoro’s conviction for second-degree murder and his mandatory life sentence with parole eligibility after fifteen years for an offense committed when he was fifteen. The court held that the sentence did not violate the Eighth Amendment, art. 26 of the Massachusetts Declaration of Rights, due process, or separation of powers, and it rejected challenges concerning expert testimony about adolescent brain development and a requested defense-of-another jury instruction.

Questions Presented
- Whether a mandatory life sentence with parole eligibility after fifteen years for a juvenile convicted of second-degree murder violates the Eighth Amendment, article 26 of the Massachusetts Declaration of Rights, due process, or separation of powers.
- Whether juvenile defendants may present expert testimony about adolescent brain development and youth-related characteristics as they bear on the particular defendant's capacity to form the intent required for murder.
- Whether the trial judge was required to instruct the jury on defense of another.
- Whether juvenile second-degree murder offenders are entitled to the same specified due process protections in parole proceedings recognized for juvenile first-degree murder offenders.
Holdings
- A mandatory sentence of life imprisonment with parole eligibility after fifteen years for a juvenile convicted of second-degree murder does not violate the Eighth Amendment or article 26. Miller's individualized-sentencing requirement was limited to mandatory life without parole, and the court declined to extend it to this sentence.
- Juveniles convicted of second-degree murder must receive the same specified due process protections in parole proceedings that the court required for juvenile first-degree murder offenders in Diatchenko II.
- Assigning parole decisions for juvenile homicide offenders to the executive branch does not violate article 30 because neither the Eighth Amendment nor article 26 requires those decisions to be vested in the judiciary.
- The trial judge properly allowed expert testimony concerning adolescent brain development insofar as it assisted the jury in evaluating this defendant's impulse control, decision-making, and capacity to form the required mental state, but properly excluded an opinion that a fifteen-year-old is categorically incapable of forming the intent required for murder.
- The trial judge was not required to instruct the jury on defense of another because, even viewing the evidence in the light most favorable to the defendant, it did not show an immediate physical threat to his sister that would make the use of force reasonably necessary.
Key quotations
“Miller’s actual holding was narrow and specifically tailored to the cases before the Court: presented with two juvenile defendants convicted of murder in the first degree, the Court concluded that a mandatory sentence of life in prison without parole violated the Eighth Amendment.” (471 Mass. at 57)
“In sum, we conclude that at present, a mandatory life sentence with parole eligibility after fifteen years for a juvenile homicide offender convicted of murder in the second degree does not offend the Eighth Amendment or art. 26.” (471 Mass. at 62)
“This information was beyond the jury’s common knowledge, it offered assistance to the jury in determining whether the defendant was able to form the intent required for deliberate premeditation or malice generally at the time of the incident, and it did not amount to an opinion that the defendant (or any other fifteen year old) was incapable of forming the intent required for murder in the first or second degree simply by virtue of being fifteen.” (471 Mass. at 67)
“In sum, we agree with the trial judge that a jury instruction on defense of another was not warranted on the evidence presented at trial.” (471 Mass. at 70)
Factual background
The fifteen-year-old defendant had been drinking alcohol and smoking marijuana before approaching a crowd outside a New Year's Eve party while carrying a knife. He confronted Markeen Starks and stabbed him multiple times; Starks died from the wounds. The defendant presented evidence of borderline cognitive functioning, emotional dysregulation, exposure to severe domestic violence, foster-care instability, and substance abuse. He argued that he had acted to protect his sister from persons associated with prior violence against her, but the evidence did not show an immediate physical threat to her when the fight began.
Procedural history
The defendant was indicted in the Superior Court Department for first-degree murder and tried in December 2010. The jury returned a verdict of second-degree murder, and the defendant received a mandatory life sentence with parole eligibility after fifteen years. The trial judge denied the defendant's posttrial motions for a new trial, reduction of verdict, resentencing, and reconsideration. The Supreme Judicial Court granted direct appellate review and affirmed the conviction, sentence, and posttrial orders.
