485 P.3d 1
Cal.2021Background
- Defendant Maurice Steskal shot and killed OCSD Deputy Bradley Riches outside a 7‑Eleven, firing ~30 rounds at close range; Steskal fled and was arrested hours later with the disassembled rifle and >100 rounds of ammunition.
- A jury convicted Steskal of first‑degree murder, found true the special circumstance of killing a peace officer, and found firearm enhancements; initial penalty jury deadlocked and a retrial returned a death verdict.
- Defense presented extensive evidence of lifelong paranoia, delusional disorder, psychosis after prior traffic stops, and expert testimony that Steskal was in a psychotic state at the time of the shooting; defendant did not deny the shooting.
- Guilt‑phase disputes included denial of an imperfect self‑defense/voluntary manslaughter instruction, exclusion of certain expert testimony as hearsay, and alleged prosecutorial misconduct in closing.
- Penalty‑phase contested evidence included a life‑sized mannequin showing wound trajectories, autopsy and patrol‑car photos, a jury view of the patrol car, victim‑impact testimony, and evidence of an attempted jail escape and contraband weapons.
- The California Supreme Court affirmed the conviction and death sentence, rejecting challenges to evidentiary rulings, prosecutorial conduct, admission of penalty evidence, and constitutional claims about the death penalty for mentally ill defendants.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Refusal to instruct on voluntary manslaughter (imperfect self‑defense) | Prosecution: evidence did not show an actual but unreasonable belief of imminent harm. | Steskal: delusional fear of police supported imperfect self‑defense instruction. | Court: No substantial evidence of fear of imminent peril; instruction properly refused. |
| Exclusion of certain expert testimony (Evidence Code § 802/hearsay) | Prosecution: case‑specific out‑of‑court statements underlying expert opinion are hearsay. | Steskal: excluded statements described delusions, not hearsay; admissible as basis for opinion. | Court: Sanchez controls; exclusion proper and harmless because expert testified extensively from admissible sources. |
| Alleged prosecutorial misconduct in guilt closings ("hero," "coward," failure to call spouse) | Prosecution: closing was fair comment on evidence and permissible to note missing expected witnesses. | Steskal: remarks appealed to sympathy, shifted burden, and invited adverse inference re: spouse (privilege). | Court: Remarks were within bounds or promptly admonished; objection sustained where required; no prejudicial misconduct. |
| Jury view of Deputy Riches’s patrol car (guilt & penalty) | Prosecution: view is probative of shot pattern, shooter/victim positions; not cumulative of photos. | Steskal: display was inflammatory, cumulative, and unduly prejudicial. | Court: Trial court did not abuse discretion under §352; view was probative and not constitutionally unfair. |
| Admission of demonstrative and graphic penalty evidence (mannequin, autopsy photos) | Prosecution: evidence illustrates circumstances and pathologist testimony; appropriate at penalty. | Steskal: exhibits were gruesome, cumulative, and unduly inflammatory. | Court: Admissible; penalty phase affords wide latitude to show crime circumstances; no abuse of discretion or due process violation. |
| Admission of attempted jail escape and contraband as aggravation (Pen. Code §190.3(b)) | Prosecution: possession of shank/blades and scraping wall + bedsheets supported inference of escape plan and implied threat. | Steskal: tools were for scraping; no evidence of intent to use violence so escape evidence is nonviolent. | Court: Evidence supported implied threat/attempted escape and was admissible; even if marginal, other admitted contraband made any error harmless. |
| Eighth Amendment challenge: categorical bar to death for severe mental illness | State: no national consensus exempts mentally ill from death penalty; Legislature best suited to define categories. | Steskal: severe mental illness (delusional disorder) should bar death or require intracase proportionality review. | Court: Rejected categorical claim; applied precedent denying categorical exemption and upheld sentence on proportionality review. |
