Commonwealth v. Bishop, 963 N.E.2d 88

Defendant Walter R. Bishop killed Sandro Andrade with gunfire after a prior confrontation on a Brockton street.
He was convicted in the Superior Court of first-degree murder on a theory of deliberate premeditation and related offenses.
On appeal, Bishop challenged voir dire, Miranda waiver, admission of a jailhouse racially charged statement, closing arguments, and jury instructions on mental impairment.
Evidence included police video-interrogation showing a knowing and voluntary Miranda waiver, and psychiatric testimony proffering both mental illness and mental impairment theories.
The Commonwealth presented rebuttal psychiatric testimony; defense experts urged impairment-based incapacity to form intent.
The Massachusetts Supreme Judicial Court affirmed the convictions and declined to reduce the murder conviction or grant a new trial under G. L. c. 278, § 33E.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Was voir dire adequate on criminal responsibility?	Seguin requires individualized inquiry for insanity opinions.	Questions were insufficient to reveal juror bias.	Voir dire adequate; no abuse of discretion.
Were the defendant's statements at the police station properly admitted?	Waiver was knowing and voluntary; statements properly admitted.	Belated suppression should apply due to invocation of silence and voluntariness issues.	Waiver voluntary; statements admitted.
Was the jailhouse racial slur admissible evidence of criminal propensity?	Slur shows racial animus supporting intent; probative value outweighs prejudice.	Evidence is prejudicial and inflammatory; should be excluded or limited.	Admission proper with limiting instruction; probative on motive/animus.
Did closing arguments amount to reversible prosecutorial error?	Some remarks alleged to inflate victim’s character and attack defense experts.	Some remarks improper; need reversal for miscarriage of justice.	No substantial likelihood of miscarriage; arguments did not warrant reversal.
Should the jury have been instructed on mental impairment versus mental illness?	Mental impairment evidence applicable to specific intent; instruction should reflect impairment.	Instruction should distinguish mental illness from impairment; risk of prejudice if misworded.	Error not prejudicial; instruction with mental illness and lack of capacity adequate.
