Zapien v. Davis, 849 F.3d 787

Background

In 1987 Conrad Zapien was convicted of first-degree murder and sentenced to death for killing Ruby Gonzalez; prosecution theory: burglary/robbery motive, eyewitness and physical evidence implicated him.
Prosecutor’s investigator found and destroyed a sealed envelope containing the defense’s strategy tape addressed to Zapien’s counsel; trial court found the investigator did not listen to it and denied dismissal motion.
Zapien’s conviction and death sentence were affirmed by the California Supreme Court (1993); he later pursued state and federal habeas relief; some claims received evidentiary hearings but were ultimately denied.
On federal habeas review the Ninth Circuit considered claims alleging: due process violation from destruction of the tape; Confrontation Clause violations from admission of sister’s and hearsay testimony; ineffective assistance of counsel (guilt and penalty phases); and juror prejudice from extrajudicial information.
The Ninth Circuit applied AEDPA deference to the California Supreme Court’s rulings and reviewed credibility and strategic-choice determinations under doubly deferential standards.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Destruction of defense strategy tape / due process	Tape’s destruction deprived Zapien of exculpatory evidence and due process because testing could show it was listened to and reveal misconduct	State courts: tape was attorney‑work product and no clearly established Supreme Court law extends Trombetta/Youngblood to this situation; no conscious suppression of exculpatory evidence	Denied — state court decision reasonable; no Supreme Court precedent clearly establishing a due‑process violation for destruction of counsel work product already known to defense
Confrontation Clause — admission of sister Inez’s preliminary hearing testimony	Admission of Inez’s preliminary‑hearing statements violated the Confrontation Clause because she refused to testify at trial	State courts relied on Ohio v. Roberts standard: prior cross‑examination at preliminary hearing provided adequate indicia of reliability	Denied — admission was reasonable under Roberts; no unreasonable application by state court
Confrontation Clause — multi‑level hearsay (Perez relaying statements about others)	Multi‑level hearsay denied confrontation rights and was unreliable	State: declarants testified at trial and were subject to cross‑examination; Green permits admission where declarant testifies	Denied — California Supreme Court reasonably applied Green; multi‑level hearsay not per se Confrontation violation
Ineffective assistance of counsel — guilt phase (impeachment, witnesses, evidence)	Counsel failed to impeach key eyewitnesses, omitted witnesses, failed to exclude or challenge damaging testimony, and failed to present medical evidence of a broken hand	State: counsel made reasonable strategic choices; impeachment risks, witness youth, and marginal/uncertain medical proof made alternative strategies unpersuasive	Denied — under Strickland and AEDPA, counsel’s tactical choices were reasonable and failure to present those items not prejudicial
Ineffective assistance of counsel — penalty phase (mitigation investigation and experts)	Counsel failed to uncover/present extensive mitigating social‑history and psychiatric/neurological evidence that could have led to life sentence	State: counsel presented substantial mitigation; additional evidence might be "two‑edged" and could have invited damaging rebuttal; investigation was not so cursory as to be constitutionally deficient	Denied — state court’s conclusion reasonable under Strickland and Wiggins; no prejudice shown
Juror prejudice from news report exposure	Juror exposed to extrajudicial report implying dangerousness; should have been dismissed or presumed prejudiced under Mattox	State: trial judge questioned juror, found he could be impartial; Mattox presumption applied and rebutted	Denied — state court reasonably upheld trial court credibility finding; no automatic dismissal required
