136 N.E.3d 680
Mass.2019Background
- On August 25, 2009, Erica Field (killed) and Shameek Garcia (survived) were shot while seated in a parked car in Dorchester; ballistics linked bullets from the scene to a single firearm. Garcia repeatedly uttered the name "Ace" immediately after being shot.
- Amos Don (known as "Ace") had traveled from Lewiston to Boston with Garcia and Field earlier that day; cell‑site data and fingerprints placed him at the scene and in the vehicle.
- Don had motive: missing heroin for which he owed suppliers; his post‑shooting statements and conduct suggested consciousness of guilt.
- At trial Don was convicted of first‑degree murder (deliberate premeditation), related assault charges, and unlicensed firearm possession; he was sentenced to life plus concurrent terms.
- Postconviction counsel discovered additional Garcia medical records after trial (BMC produced over 2,000 pages), and raised ineffective assistance and newly discovered evidence claims (medical/radiology, ballistics, Garcia as a DEA informant/third‑party culprit).
- The trial judge admitted evidence of Don’s prior attempts to acquire firearms for limited purposes (motive, familiarity), and the Superior Court denied Don’s new‑trial motion and motion to reconsider; the SJC affirmed.
Issues
| Issue | Commonwealth's Argument | Don's Argument | Held |
|---|---|---|---|
| 1) Whether posttrial medical records are "newly discovered" and warrant a new trial | Records were not materially new to undermine conviction; defendant had access to core information pretrial | Newly produced radiology reports would show Garcia was shot through the mouth, undermining Commonwealth's back‑seat shooter theory | Not newly discovered in the Grace sense (and even if new, not likely to cast real doubt); no new trial granted |
| 2) Failure of trial counsel to obtain/introduce medical/ballistics experts (ineffective assistance) | Defense strategy reasonably avoided forensic battle; proffered experts would be cumulative or address nonessential scenarios | Counsel was ineffective for not challenging wound trajectory and door‑bullet origin, which could show shooter outside car or different position | Even if performance imperfect, no substantial likelihood of miscarriage of justice given strength of circumstantial evidence; claim fails |
| 3) Failure to call neurologic expert to challenge Garcia’s post‑shoot identification (ineffective assistance) | Jury heard evidence of Garcia's head injuries and memory loss; counsel argued unreliability; expert would have been only incremental | An expert would have shown perseveration or impaired decision‑making, undermining "Ace" as an identifier | Proffered expert would have added little beyond existing record; no substantial likelihood of different outcome; claim fails |
| 4) Admission of prior attempts to purchase firearms (propensity/prejudicial evidence) | Evidence was relevant to motive, timing (why Don waited to get a gun) and familiarity with firearms; trial judge limited use and instructed jury | Prior attempts involved guns that could not have been the murder weapon and were unfairly prejudicial | Admission proper for limited purposes; any error harmless given limited attention to evidence and strong other proof |
