Commonwealth v. Drayton, 96 N.E.3d 163

Defendant Kenji Drayton was convicted of first‑degree murder and unlawful firearm possession based almost entirely on the testimony of James Jackson, an apartment resident who said he saw Drayton shoot Michael Greene.
Jackson had serious credibility problems (drug/alcohol use, inconsistent statements to police, 911 call, and grand jury testimony). Physical evidence tying Drayton to the killing was minimal.
Eighteen months after conviction, Debra Bell (later deceased) signed an affidavit saying she and Jackson were in the bathroom smoking crack and engaging in sexual activity at the time of the shooting, and thus neither could have seen the shooter.
Supporting affidavits from Debra’s sister (Betty Jo) and Joseph Anderson corroborated aspects of Debra’s account; Debra died soon after executing her affidavit.
The trial court initially denied a new‑trial motion as inadmissible hearsay (not a dying declaration). This Court (Drayton I) remanded for an evidentiary hearing to determine whether the affidavit fit a narrow constitutional hearsay exception (Chambers test), whether it was newly discovered, and whether it cast real doubt on the convictions.
On remand the motion judge found Debra’s affidavit trustworthy (impending death, lack of motive to lie, corroboration), newly discovered, and sufficiently probative to cast real doubt; the judge granted a new trial. The Commonwealth appealed.

Issue	Commonwealth's Argument	Drayton's Argument	Held
Whether Debra's affidavit fits the narrow constitutional hearsay exception (Chambers)	Affidavit is inadmissible hearsay and should not overcome rule limits	Affidavit is critical and bears persuasive guarantees of trustworthiness (Chambers)	Affidavit admissible under Chambers: judge found trustworthiness (impending death, no motive, corroboration)
Whether affidavit qualified as newly discovered evidence	Not newly discovered or would only be impeachment	Debra was unavailable; defense could not reasonably discover her posttrial affidavit earlier	Affidavit was newly discovered: unavailable witness and no reasonable way to obtain the exculpatory statements at trial
Whether the affidavit casts real doubt on the convictions	Affidavit merely impeaches Jackson and would not have changed jury’s verdict	Affidavit directly contradicts the only percipient witness and undermines the Commonwealth’s entire case	Affidavit casts real doubt and likely would have been a significant factor in deliberations; new trial warranted
Whether the motion judge abused discretion in granting a new trial	Judge erred as a matter of law in admitting and relying on hearsay	Judge acted within discretion given record and remand instructions	No abuse of discretion; decision affirmed, convictions vacated and remanded for new trial
