People v. Chhoun, 11 Cal.5th 1

Background

In August 1995, defendant Run Peter Chhoun (a Tiny Rascals Gang leader) and accomplices committed a home-invasion robbery at the Nguyen residence in San Bernardino; five family members were killed and three‑year‑old Dennis survived with a hand wound. Chhoun was convicted of five murders, burglary, and robberies; special circumstances were found and jury returned a death sentence.
Prosecution introduced evidence of other recent violent incidents involving defendant and TRG members (notably Sacramento and Spokane home invasions and two drive‑by shootings) to show intent, premeditation, and a common scheme; accomplices Karol and Evans testified for the People. Pan (co-defendant) was acquitted at close of the People’s case.
A gang expert testified about Tiny Rascals’ structure and the modus operandi of Asian home‑invasion robberies; the court gave limiting instructions on use of other‑crimes and gang evidence.
Several procedural and evidentiary disputes arose: admission of the Sacramento evidence and gang testimony (Evid. Code § 1101/352), use of witness support persons (Pen. Code § 868.5), admission/exclusion of hearsay at penalty phase (including whether out‑of‑court statements by co‑participant “Scrappy” were admissible as statements against penal interest under Evid. Code § 1230), and numerous jury‑instruction challenges.
The Supreme Court affirmed the convictions and death sentence, rejecting defendant’s challenges to the evidentiary rulings, the support‑person procedure, instructional claims, and sentencing‑scheme constitutional challenges; it also upheld the $10,000 restitution fine.

Issues

Issue	People’s Argument	Chhoun’s Argument	Held
Admissibility of Sacramento other‑crimes evidence (Evid. Code §1101(b))	Evidence of Sacramento crimes is relevant to show intent, premeditation, and common plan for Elm Street murders; limiting instructions should mitigate prejudice.	Evidence was inflammatory and irrelevant; admission violated §1101 and §352 and deprived defendant of due process.	Admissible: Sacramento crimes sufficiently similar to show intent/premeditation and common plan; court did not abuse discretion under §1101(b) or §352; limiting instructions adequate.
Gang‑membership expert testimony	Gang evidence is relevant to motive, modus operandi, roles among participants, and identity; limited testimony and instructions prevent prejudice.	Testimony was overbroad, inflammatory, and impermissibly suggested bad character/propensity.	Admissible: testimony narrowly limited, probative for intent/plan/identity; §352 balancing proper and limiting instructions sufficient.
Witness support persons (Pen. Code §868.5)	Support persons may accompany witnesses for moral support; presence does not deny confrontation so long as there is no prompting.	Failure to conduct case‑specific need assessment and to admonish each time violated confrontation and due process.	No constitutional violation: statute does not require case‑specific showing in all instances; absent evidence of prompting/influence, presence harmless; any failure to admonish was harmless.
Admission of hearsay at penalty phase (Onkhamdy interview)	Prior inconsistent statements and adoptive admission doctrines permit admission; testimony was admissible and harmless if any error.	Admission of hearsay about Spokane talks violated confrontation and due process.	Admissible as prior inconsistent statement; underlying adoptive‑admission issue unclear but any error harmless given strong corroborating evidence.
Exclusion of Scrappy’s out‑of‑court inculpatory statements (Evid. Code §1230)	N/A (People opposed admission).	Defense sought to admit to show another party was primary shooter; statements were declarations against penal interest and reliable.	Court did not abuse discretion excluding them: statements were late, inconsistent with prior accounts, of questionable trustworthiness and not sufficiently against penal interest.
Instructional challenges (first‑degree theories, unanimity, CALJIC pattern instructions)	Standard instructions correctly state law; no unanimity requirement as long as jurors unanimously find statutory murder.	Instructions diluted reasonable‑doubt standard, required unanimity on theory, or otherwise violated rights.	Rejected: established California precedent permits the instructions used; no constitutional error.
Restitution fine and Apprendi challenge (§1202.4)	Fine is within statutory range imposed by court after conviction; Apprendi not implicated.	Imposing maximum fine without jury findings or consideration of inability to pay violated Apprendi and discretion requirements.	Rejected: fine is part of statutory sentencing range following conviction; defendant bears burden to show inability to pay and court’s exercise of discretion was proper.
