90 Cal.App.5th 1093
Cal. Ct. App.2023Background
- Werntz was convicted in 2014 of second-degree murder for the death of her infant daughter Montana and sentenced to 15 years to life; earlier appeals affirmed the conviction.
- Werntz petitioned under Penal Code §1172.6 (formerly §1170.95) for resentencing; after initial summary denial and an appellate remand, the trial court held an evidentiary hearing and denied the petition.
- Factual record: Montana suffered skull fractures and a tibia fracture (the tibia showing healing from 3–4 weeks earlier); Werntz’s earlier child Jason died of inflicted trauma and Werntz concealed his remains; another infant, Michael, had extensive, healed injuries when recovered.
- At the §1172.6 hearing the prosecutor argued Werntz was guilty as a direct aider and abettor by failing to protect Montana (implied malice), pointing to Werntz’s concealment of remains, inconsistent explanations, failure to seek medical help or notify authorities, and the other children’s injuries.
- The trial court found the People proved beyond a reasonable doubt that Werntz failed to protect Montana and thus was guilty of implied-malice second-degree murder; Werntz appealed arguing insufficient evidence and that aiding-and-abetting implied-malice is no longer a valid theory.
Issues
| Issue | Plaintiff's Argument (People) | Defendant's Argument (Werntz) | Held |
|---|---|---|---|
| Proper standard of appellate review of §1172.6 evidentiary denial | Substantial-evidence review applies to the trial court’s factual findings | Court should review de novo because findings were based on the cold record | Substantial-evidence standard applies (defer to trier of fact) |
| Validity of aiding-and-abetting implied-malice murder after SB 1437 / SB 775 | Aiding-and-abetting implied malice remains a viable theory; aider must personally harbor requisite mens rea | Aiding-and-abetting liability incompatible with implied malice because accomplice principles require specific intent | Court rejects Werntz’s challenge; aiding-and-abetting implied malice is a valid theory |
| Sufficiency of evidence that Werntz acted with implied malice (failure to protect) | Evidence (prior child homicide, concealment of remains, Montana’s visible earlier leg fracture, failure to seek care, concealment) supports inference Werntz knew of danger and acted with conscious disregard | No solid evidence she knew of abuse or Montana’s need for treatment; defense expert testimony undermines medical conclusions | Substantial evidence supports implied malice by omission as a direct aider/abettor; petition denial affirmed |
| Whether trial court’s reasoning required finding Werntz was direct perpetrator | People argued trial court found Werntz aided/abetted by omission rather than killed Montana | Werntz contended the court’s language implied a direct perpetrator finding | Court construed findings as aiding-and-abetting by failure to protect, not as finding Werntz was the direct assailant |
