Background
Mariano Garces, Jr. was convicted of second-degree murder for killing his girlfriend, Amie Kaholoaʻa, during an argument at their home. After calling 911 and later returning from the mountains, Garces was detained and taken to the Maui Police Department station. Before detectives questioned him, they used an MPD Miranda form that gave the traditional four warnings but did not expressly say that he could stop answering questions or request counsel after questioning began.
Garces confessed during the custodial interview. He sought suppression, arguing that the incomplete advisement and his suicidal ideation and mental distress made his waiver involuntary. The Circuit Court of the Second Circuit denied suppression, and the jury convicted him. The Intermediate Court of Appeals affirmed.
The Court’s Holding
The Supreme Court of Hawaiʻi affirmed. It held that, under the law governing Garces’s interrogation, he knowingly, intelligently, and voluntarily waived his Miranda rights. Although Garces appeared suicidal, the record showed that he had asked to speak with police, was coherent and cooperative, did not appear intoxicated, and was not subjected to threats, force, coercion, or promises. The court held that the circuit court’s finding that his suicidal statements were not credible absent action was clearly erroneous, but the error was harmless.
The court also adopted a new rule under article I, section 10 of the Hawaiʻi Constitution. Going forward, law enforcement must expressly tell custodial suspects that they may stop answering questions at any time and may request an attorney at any time after questioning begins. The rule applies purely prospectively and takes effect October 23, 2026, so it did not invalidate Garces’s waiver or conviction.
Key Takeaways
- Hawaiʻi now requires an express fifth Miranda warning informing suspects that they may end questioning at any time.
- Officers must also make clear that a suspect may request counsel after initially waiving Miranda rights.
- The new requirement is prospective only and does not apply to interrogations before October 23, 2026.
Why It Matters
The decision expands state constitutional protections beyond the federal Miranda baseline and requires Hawaiʻi law-enforcement agencies to revise forms and training. But defendants whose interrogations predate the effective date cannot rely on the new warning requirement alone to suppress their statements.
