In re Interest of J.A., 186 A.3d 266

Background

Victim's iPhone (in pink glittery case) was stolen at a bus stop; officers used "Find My iPhone" to locate the device at a nearby house but the phone powered off after ~2 minutes.
Officers went to the house, saw the matching phone case through a first-floor window, knocked with no response, found an unlocked window and entered without a warrant; they performed a protective sweep and found J.A., a 17‑year‑old, under bedroom covers and in possession of clothing matching the robber's description.
Officers handcuffed J.A. and remained in the home; family members (mother and older brother) later arrived. The mother consented in writing to a search; the brother, unprompted and accompanied by an officer, searched another bedroom, found the phone, and handed it to police.
J.A. (juvenile) was charged with robbery; he moved to suppress the phone as the product of an unlawful warrantless entry. The trial court denied suppression; Appellate Division affirmed, finding probable cause and exigent circumstances (hot pursuit) justified entry and treating the brother’s recovery as non‑state action.
The Supreme Court of New Jersey held the officers lacked exigent circumstances to justify warrantless entry (rejecting hot pursuit here) but concluded the brother’s independent, voluntary retrieval of the phone was an intervening, non‑state action that purged the taint, so the exclusionary rule did not bar admission of the phone. The Court thus affirmed the result but modified the reasoning.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether officers' warrantless entry was justified by exigent circumstances / hot pursuit	State: probable cause + fear evidence would be moved/destroyed and concern for safety justified immediate entry	J.A.: no basis to believe he was dangerous or knew police were pursuing him such that he would destroy evidence; phone theft alone not an exigency	Entry not justified; exigent circumstances/hot pursuit did not apply (warrantless entry unconstitutional)
Whether the exclusionary rule bars admission of the phone when a private family member retrieved it after unlawful entry	J.A./amici: brother’s recovery was fruit of illegal police presence; his search was influenced by officers so evidence must be suppressed	State: brother acted independently and voluntarily; his retrieval was non‑state action attenuating any taint	Held admissible: brother’s independent, voluntary actions were sufficiently attenuated and not state action, so exclusionary rule inapplicable
Whether mother’s written consent cured any illegality	N/A (alternative argument)	State: consent validated search	Court did not decide because attenuation rendered exclusionary rule inapplicable; did not reach consent issue
Standard for attenuation analysis after unlawful police conduct	N/A	N/A	Applied Brown factors (temporal proximity, intervening circumstances, flagrancy of misconduct) and found intervening circumstance (brother’s voluntary search) broke causal chain
