Background

  • On November 10, 2013, Leiva and two hooded companions (one identified by the victim’s girlfriend as Amadi Sosa) confronted William Serrano on a small porch; Leiva produced a gun and shot Serrano seven times; Serrano later died.
  • The girlfriend identified Sosa at trial; surveillance footage from a nearby apartment and ballistics evidence linked the scene to Leiva and to ammunition recovered from Sosa’s residence of the same caliber/markings as casings at the scene.
  • Sosa and Leiva were tried jointly as joint venturers; Sosa was convicted of first‑degree murder (deliberate premeditation and felony‑murder), armed assault with intent to rob, and unlawful possession of ammunition.
  • Sosa moved to sever, objected to use of a compilation surveillance video, argued insufficiency as to deliberate premeditation and felony‑murder, and challenged jury instructions (including on unlawful possession of ammunition and involuntary manslaughter).
  • The motion judge (on remand from this court) denied Sosa’s Mass. R. Crim. P. 30(b) new‑trial motion (ineffective assistance claim based on not moving to suppress basement ballistics), and this Court affirmed all convictions except it vacated the unlawful‑ammunition conviction and remanded that count for retrial.

Issues

Issue Commonwealth's Argument Sosa's Argument Held
Severance / prejudicial joinder & Rule 3.3(e) testimony Joint trial proper; Leiva’s narrative testimony and the trial court’s limits on cross‑examination were proper for trial management Denial of severance violated due process and confrontation rights because Leiva’s testimony (invoking rule 3.3(e)) was false/bias‑motivated and the Commonwealth allowed it to stand No reversible error: prosecutor cross‑examined Leiva vigorously; limits on probing invocation of rule 3.3(e) were not an abuse (bias theory too attenuated); joinder denial not an abuse of discretion
Use of compilation surveillance video (authentication) The complete footage was authenticated and admitted; compilation was a subset of admitted footage and not prejudicial Compilation was never authenticated/marked/admitted and its use was improper Even assuming error, no prejudice because compilation was cumulative of authenticated complete footage; better practice would be to authenticate excerpts
Sufficiency — deliberate premeditation as joint venturer Evidence (placement, knowledge of gun, participation in running pockets, blocking escape, ammunition links) permitted inference Sosa shared intent to kill and had cool reflection Sosa misidentified; at most intended to rob or intimidate; sudden shooting precludes deliberate premeditation Evidence sufficient: jury could infer shared intent and some period of reflection from circumstances; motion for required finding properly denied
Sufficiency / instruction — felony‑murder element re: maximum penalty Trial judge correctly instructed that armed robbery is a felony punishable by life as a matter of law Jury should have been instructed to find as a factual element that the predicate felony is punishable by life No error: maximum penalty is a question of law for the judge, and judge’s instruction was correct
Unlawful possession of ammunition — licensure element after Bruen/Guardado Commonwealth can reprove ammunition possession without prior licensure instruction Jury was not instructed that lack of a license is an essential element of §269, §10(h) Conviction vacated: licensure is an essential element and jury was not instructed; remand for retrial on that count required
Request for involuntary manslaughter instruction Not necessary because murder in second degree (malice/felony‑murder) was given as lesser option Jury could have found wanton/reckless conduct warranting involuntary manslaughter Even if omission was error, no prejudice because jury had second‑degree murder option and convicted first‑degree on both theories
Motion for new trial — ineffective assistance (failure to suppress basement evidence) Defendant failed to show he had reasonable expectation of privacy in basement; motion judge correctly denied new trial Counsel ineffective for not filing motion to suppress; affidavit/warrant lacked probable cause for basement search Motion judge did not err: defendant bore burden to show expectation of privacy and record was inconclusive; no substantial likelihood of a different outcome
