102 N.E.3d 391
Mass.2018Background
- Defendant Patrick Waweru attacked and fatally stabbed his former partner in her sister’s Lynn apartment and also struck the sister with a two-by-four; he was arrested soon after and admitted to taking pills and a suicide attempt.
- Defendant has a documented history of mental illness (diagnoses including bipolar disorder, past hospitalizations, and prior threats toward the victim); at trial he admitted the killing but asserted lack of criminal responsibility (insanity) as his defense.
- At the hospital the night of his arrest a treating psychiatrist, Dr. McGovern, conducted a suicide-risk/mental-status evaluation in the defendant’s ICU room in the presence of two police officers guarding him; McGovern’s testimony about statements he made was admitted at trial.
- The jury convicted Waweru of first-degree murder (premeditation and extreme atrocity theories) and related offenses; he was acquitted on one charge; defendant appealed from denial of suppression, jury instructions, and denial of his request for a jury‑waived trial.
- The Supreme Judicial Court affirmed: it held the hospital statements voluntary, held the psychotherapist‑patient privilege was not automatically waived by police presence (but any evidentiary error was harmless), rejected challenges to several jury instructions, and upheld the statutory ban on jury‑waived trials in capital cases.
Issues
| Issue | Commonwealth's Argument | Waweru's Argument | Held |
|---|---|---|---|
| Admissibility of hospital statement to treating psychiatrist | Statement was voluntary and admissible; psychiatrist was not police agent | Statement involuntary, privileged, and obtained in violation of due process because police present and no Lamb warnings | Statements voluntary; privilege did attach but police presence did not automatically waive it; admission harmless given overwhelming evidence of premeditation; no Lamb warning required |
| Waiver of psychotherapist‑patient privilege by police presence | Presence of guards did not waive privilege because consultation necessary for treatment/public safety | Presence of officers in room waived privilege or rendered statements inadmissible | Presence of police guarding patient does not automatically waive the privilege; privilege would remain unless statutory exception applies; admission harmless here |
| Jury instructions on presumption of sanity and insanity consequences | Instructions followed then‑controlling precedent and properly stated burden; Mutina instruction proper at time of trial | Presumption of sanity instruction and Mutina consequences instruction misstated law and risked jury confusion | Instruction on sanity inference now disfavored by later law but here not prejudicial; Mutina instruction acceptable because trial predated Chappell changes |
| Failure-to-take‑medication and reasonable‑doubt instructions | Instructions did not mislead or shift burden; no evidence supporting instruction on voluntary medication cessation | Jury should have been instructed that failure to take prescription meds cannot alone negate insanity defense | No instruction required; Berry/DiPadova drug‑use instructions concern voluntary intoxication and were inapplicable; reasonable‑doubt instruction acceptable |
