Commonwealth v. Delacruz, 976 N.E.2d 788

Delacruz was convicted of first-degree murder on theories of deliberate premeditation and extreme atrocity or cruelty, and of unlawful firearm possession.
Victim Tyrice Brown sustained four gunshot wounds and died from torso injuries including lung, liver, intestine, and external iliac artery damage.
Surveillance video captured the shooting; a police officer recognized Delacruz from the footage.
Delacruz was arrested in Wilmington, Delaware, after Boston detectives obtained a murder warrant and traced him there.
Delacruz made incriminating statements after being read Miranda warnings and Rosario waiver forms; he later contested suppression.
The defense presented neuropsychological evidence suggesting cognitive limitations but did not offer an opinion on legal responsibility; the defense urged a lesser-included verdict based on mental impairment.
Pretrial and trial judges denied continuance/change of counsel requests and denied suppression motions; Delacruz appealed and challenged jury instructions on mental impairment.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Counsel of choice and continuance denial	Delacruz argues Sixth Amendment violation from denial	Delacruz asserts improper denial of change of counsel	No abuse of discretion; denial proper
Motions to suppress statements	Commonwealth prevailed on voluntariness and Miranda waiver	Delacruz claims non-voluntary waiver given cognitive limits	Waiver and statements voluntary beyond a reasonable doubt
Rosario/ arraignment timing for out-of-state arrest	Safe harbor upheld as applicable to prompt arraignment	Out-of-state context limits Rosario applicability	Rosario/landen rules satisfied; delay did not violate rights
Jury instructions on mental impairment and murder elements	Mental impairment relevant to deliberate premeditation and cruelty	Need reinstruction on impairment's effect	No reversible error; adequate main charge and appropriate reinstruction absent request
Relief under G. L. c. 278, § 33E	No basis to reduce murder verdict or grant new trial	Potential grounds for relief	No relief warranted
