Commonwealth v. Sanchez
476 Mass. 725
| Mass. | 2017Background
- Victim found stabbed, strangled, and burned in her Springfield home on July 12, 2009; death caused by stab wounds and smoke inhalation. Fire determined to be intentionally set in the victim’s bedroom.
- Defendant (estranged husband) had prior abuse-prevention order, separation, custody dispute, and motive related to pending divorce and custody.
- Surveillance and witness timeline: defendant's SUV left mobile home park ~11:24–11:30 PM; neighbor heard a scream and saw a man and woman arguing at victim’s door minutes later; SUV returned ~12:02 AM.
- Physical and forensic evidence: bruises on defendant’s hands; defendant’s left hand tested positive for blood; DNA mixtures from a T‑shirt and fingernail scrapings included profiles consistent with the victim and potentially the defendant (STR and Y‑STR results).
- Procedural posture: defendant convicted by Superior Court jury of first‑degree murder (premeditation and extreme atrocity/cruelty), arson of a dwelling, and violation of a G. L. c. 209A order; conviction affirmed on appeal.
Issues
| Issue | Commonwealth's Argument | Sanchez's Argument | Held |
|---|---|---|---|
| Sufficiency of evidence for first‑degree murder and arson | Circumstantial evidence (motive, timeline, witness sighting, injuries, DNA, fire origin) sufficient to prove guilt beyond a reasonable doubt | Evidence was circumstantial; lack of blood/soot on defendant or in his vehicle undermines proof | Affirmed: evidence sufficient for premeditation and extreme atrocity/cruelty and for arson |
| Confrontation clause re: substitute DNA witness (Barber testifying about data produced by Knasas) | Barber independently reviewed raw data, formed her own opinions, and was cross‑examined; no Sixth Amendment violation | Testimony relayed another analyst's results; required proof of unavailability of original analyst | Affirmed: no confrontation violation; substitute expert may testify based on independent review without showing unavailability |
| Confrontation clause re: electrical investigation (Percy vs. Hall) | Percy personally inspected scene, reviewed electrical sources, formed independent opinion that fire was deliberate | Failure to call electrician Hall deprived defendant of chance to confront underlying opinion that ruled out electrical cause | Affirmed: Percy gave independent opinion and was cross‑examined; no confrontation violation |
| Miranda and voluntariness of statements (July 12, 17, 18) | Waivers were knowing and voluntary under totality of circumstances; defendant reinitiated on July 18 after invoking counsel on July 17 | Defendant was in custody, impaired by heroin/alcohol/withdrawal, mentally ill, learning disabled; invocation of counsel on July 17 tainted subsequent statements | Affirmed: July 12 not custodial; July 17 waiver valid though officer made inappropriate comment after invocation (did not produce statements); July 18 defendant initiated contact and validly waived; statements voluntary |
| Postconviction motion for new trial (ineffective assistance / mental state) | Motion judge credited trial counsel's affidavit and found no substantial issue warranting an evidentiary hearing | Defendant alleged hearing voices and counsel failed to address mental state; affidavits supported claim | Affirmed: denial without hearing not an abuse of discretion; judge did not credit defendant's affidavits |
| G. L. c. 278, § 33E review (reduce degree of guilt/new trial) | Record contains no mitigating grounds warranting reduction or new trial | Requested reduction to manslaughter or second‑degree murder | Affirmed: no relief under §33E |
