State v. Yazzie, 437 P.3d 182

Background

Officer Temples responded to a 9:43 p.m. welfare check after a downstairs neighbor reported loud thumping from an upstairs apartment.
Over 8–10 minutes he loudly knocked and announced himself; the only audible responses were an infant crying and a small child repeatedly calling “Mommy! Mommy, wake up!” and intermittent doorknob rattling.
Believing an adult inside might be incapacitated and the children unattended, Temples opened an unlocked door, briefly announced again, then conducted a short safety sweep of adjoining rooms and returned to rouse the occupants.
Officers administered breath tests, arrested the adults for DUI-related offenses, and the State charged defendant with negligent child abuse; defendant moved to suppress evidence obtained after the entry.
The district court denied the suppression motion; the Court of Appeals reversed. The Supreme Court of New Mexico granted certiorari and reversed the Court of Appeals, upholding the entry and sweep under both the Fourth Amendment and Article II, § 10 of the New Mexico Constitution.

Issues

Issue	Plaintiff's Argument (State)	Defendant's Argument (Yazzie)	Held
1) Was the warrantless entry objectively reasonable under the Fourth Amendment emergency-assistance doctrine?	The totality of facts (children crying, child calling an unresponsive mother, doorknob rattling, welfare-check call) gave reasonable grounds to believe immediate aid was needed.	The facts were insufficient: noises were intermittent/ordinary, no signs of violence/injury, no neighbors corroborating, and entry was speculative.	Held: Yes. Viewing the totality of circumstances and deferring to the district court’s factual findings, the entry was objectively reasonable.
2) Is an officer’s subjective motivation relevant to Fourth Amendment emergency-entry analysis?	N/A (State relied on objective reasonableness).	N/A (defendant argued entry was pretext to investigate/criminally charge).	Held: Under the Fourth Amendment, officer’s subjective intent is irrelevant (Brigham City). New Mexico adopts the two-part objective test: (1) reasonable grounds to believe an emergency exists; (2) reasonable basis to associate the emergency with the area searched.
3) Was the ensuing safety sweep’s scope reasonable (limited to emergency needs)?	The sweep was brief (~30 seconds), flashlight checks of adjoining rooms; bottles were in plain view; scope was tied to officer safety and checking for others in need.	The sweep went beyond aid and served investigatory/seizure purposes (requesting PBT, no medics called).	Held: Yes. The sweep was limited in manner and scope to ascertain if anyone else needed assistance and to ensure officer safety.
4) Under Article II, § 10 of the New Mexico Constitution, must courts consider the officer’s subjective motive (i.e., adopt full Ryon three-part test)?	State argued federal standard suffices; entry satisfies objective prongs.	Yazzie urged revival/adoption of the full Ryon test (including subjective-motivation inquiry) under the state constitution for greater protection.	Held: New Mexico applies the interstitial approach and concludes Article II, § 10 provides greater protection; therefore the full three-part Ryon test (including subjective-motivation inquiry) governs under the state constitution. Applying it, the entry and sweep were reasonable and the officer’s primary motivation was to render aid.
