People v. Espino CA4/1, D083213

Isak Espino was convicted by a jury of first-degree murder (Pen. Code, § 187) with related firearm enhancements (§ 12022.53) after the fatal shooting of Dante Lopez outside a bar in Spring Valley, California.
The prosecution’s case relied heavily on George Gomez III, Espino’s friend and a percipient witness, who identified Espino as the shooter in both his police interview and at trial. Gomez had accepted a plea deal to testify against Espino.
The defense theory was that another individual present, Demetri H., could have been the shooter and that Gomez was biased against Espino due to fear of Demetri's criminal history.
The trial court restricted the defense from cross-examining Gomez about his knowledge of Demetri’s past convictions; Demetri’s prior criminal acts were only admitted for impeachment and credibility.
Additional evidence included surveillance footage, DNA, motive (betting dispute), and consciousness of guilt (Espino’s texts and jail calls).
On appeal, Espino challenged the restriction on cross-examination, the jury instructions related to accomplice testimony, and a clerical error in the sentencing abstract.

Issue	Espino's Argument	State's Argument	Held
Limitation on cross-exam of Gomez re: Demetri’s criminal history	Restriction prevented showing Gomez’s bias/motive to falsely identify Espino; error violated state law and Confrontation Clause	Minimal probative value, risked confusion/prejudice; no constitutional violation	Error of state law, but harmless; no Confrontation Clause violation
Jury instruction on accomplice corroboration (Gomez only, not Demetri)	Required for Demetri; omission prejudicial	Record lacks substantial evidence Demetri was an accomplice	Even if error, harmless—ample corroborating evidence exists
Abstract of judgment error (Three Strikes designation)	Sentenced as if under Three Strikes law despite no such pleading/finding	Agreed; mistake made	Correction ordered for the abstract of judgment
