State v. Hernandez, 911 N.W.2d 524

Background

Desiderio C. Hernandez was charged with first-degree murder, use of a firearm to commit a felony, and possession of a firearm by a prohibited person for the shooting death of his cousin Joseph Debella; trial resulted in convictions and consecutive sentences including life imprisonment.
After an arrest following an hours-long standoff, Hernandez was interviewed ~12 hours later in a recorded, ~2-hour custodial interview by Nebraska State Patrol investigators; he made various rambling statements and ultimately confessed on video.
Hernandez moved to suppress the interview arguing he was involuntarily speaking due to residual methamphetamine intoxication, did not validly waive Miranda rights, and had invoked his right to remain silent during the interview. The district court denied suppression.
Hernandez also moved in limine to redact portions of the interview as irrelevant or unfairly prejudicial under Neb. Evid. R. 401–403; the court excluded some prior-acts remarks but admitted family- and personality-related statements as relevant to voluntariness.
At trial the prosecutor made several impassioned closing remarks—some characterized by the court as improper prosecutorial comments (appeals to emotion, name-calling)—but the district court denied Hernandez’s mistrial motion; on appeal the Nebraska Supreme Court affirmed.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Hernandez)	Held
1) Were Hernandez’s statements voluntary (Fifth Amendment/ Due Process)?	Statements were voluntary; interview showed no coercion, calm interviewers, and coherent responses.	Statements involuntary due to residual methamphetamine and mental state; coercion by state actors rendered confession unreliable.	Held: Voluntary. No coercive police conduct; intoxication alone did not render confession involuntary. Court affirmed denial of suppression.
2) Did Hernandez validly waive Miranda rights?	Waiver was knowing and voluntary—he acknowledged rights, said anything could incriminate him, agreed to talk, and gave both implied and express oral waiver.	He lacked capacity to knowingly waive due to drugs/mental state; waiver invalid.	Held: Valid waiver. Warnings given, understood, and conduct/statements established implied and express waiver.
3) Did Hernandez clearly invoke the right to remain silent mid-interview?	Investigator honored clear invocation at end; earlier remark was ambiguous and non‑equivocal invocation required.	"I think I’ll probably stop talking now" was an invocation and required cessation of questioning.	Held: Not invoked. The mid-interview remark was equivocal; only the clear later invocation ended the interview.
4) Were unredacted portions of the interview admissible under relevance and Rule 403?	Statements were relevant to voluntariness and had probative value; prejudice did not substantially outweigh probative value for most remarks.	Family, gang, and other statements were irrelevant and unfairly prejudicial and should have been redacted.	Held: No abuse of discretion. Court sustained redaction of the most prejudicial parts but properly admitted other statements as relevant to voluntariness.
5) Did prosecutor’s closing remarks require a mistrial (prosecutorial misconduct)?	Some remarks were permissible inferences from evidence; others were improper but harmless in context of overwhelming evidence.	Closing contained improper personal opinions and inflammatory appeals that prejudiced the jury and warranted mistrial.	Held: Some remarks constituted prosecutorial misconduct (personal opinion; emotional appeals; name-calling), but misconduct was not prejudicial given the strength of the evidence; no mistrial required.

Colorado v. Connelly, 479 U.S. 157 (voluntariness requires coercive police conduct; mental illness/intoxication alone insufficient)
Berghuis v. Thompkins, 560 U.S. 370 (waiver of Miranda can be implied by uncoerced statements after warnings)
Davis v. United States, 512 U.S. 452 (invocation of right to counsel/silence must be clear and unambiguous)
North Carolina v. Butler, 441 U.S. 369 (an express written waiver is not required; waiver may be inferred)
Colorado v. Connelly cited earlier also supports the voluntariness standard focused on police overreaching and state action
