State v. Joseph D. Herrera, 364 P.3d 1180

Background

On December 24–25, 2011, Joseph Herrera and his girlfriend Stefanie Comack argued at Herrera’s parents’ home; Herrera had taken two of his father’s handguns without permission and had used methamphetamine and marijuana earlier that morning.
Herrera retrieved a handgun from a nightstand during the argument; he removed the magazine but a round remained in the chamber, and the gun discharged, killing Stefanie.
Herrera gave varying accounts: the gun “went off” while unloading, he pulled the slide and it fired, or Stefanie grabbed the barrel and it fired while he was raising it toward himself.
Forensic and medical testimony indicated the gun was pressed to Stefanie’s forehead when it fired and the firearm required a trigger pull to discharge; Herrera had prior gun experience.
Herrera was charged with second-degree murder; at trial the State introduced evidence and witnesses to show Stefanie intended to end the relationship. The jury convicted Herrera of second-degree murder and he was sentenced to life with 22 years fixed.
On appeal the Idaho Supreme Court found the State elicited highly prejudicial testimony about Herrera’s alleged prior bad acts and that the prosecutor violated pretrial evidentiary limitations, depriving Herrera of a fair trial; the conviction was vacated and the case remanded.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Sufficiency of evidence of malice for 2nd-degree murder	State: evidence (gun to forehead, trigger required, Herrera’s drug use/anger, gun experience) supports implied malice / jury question	Herrera: belief that gun was unloaded precludes malice; at most manslaughter	Court: belief a gun is unloaded is not a legal bar to malice; totality of circumstances can show implied malice; evidence was sufficient to submit murder to jury
Admissibility of victim’s out-of-court statements (state-of-mind)	State: statements showed Stefanie was unhappy and intended to leave, relevant to motive/state of mind	Herrera: many statements were hearsay, irrelevant, and highly prejudicial; some testimony violated pretrial rulings	Court: much of the testimony exceeded permissible state-of-mind evidence, and the prosecutor elicited barred prior-bad-act evidence; this violated the court’s order and was prejudicial, warranting reversal
Prosecutorial conduct in eliciting excluded testimony	State: limiting instructions cured any prejudice; testimony was admitted for non-truth (state-of-mind)	Herrera: prosecutor intentionally elicited excluded prior-abuse evidence to inflame jury	Held: Court found the questioning appeared deliberately designed to elicit prohibited testimony; given its prejudicial effect and deliberate violation of the court’s order, Herrera was denied a fair trial
Harmless-error analysis	State: even if some testimony improper, other evidence supports conviction so error was harmless	Herrera: improper testimony was outcome determinative and not harmless	Court: because the State deliberately elicited forbidden, highly prejudicial evidence of prior bad acts, the error was not harmless; conviction vacated
