Commonwealth v. Tuschall, 71 N.E.3d 445

Neighbor complained over three days of a persistent "smell like drugs" from defendant Kyle Tuschall’s apartment, causing headaches and distress to her dog. Police delayed response; detectives visited on the third day.
Detectives smelled a strong chemical odor at the building and knocked; no answer. With the building owner’s son’s assistance they entered after calling the occupant’s girlfriend by name to look for her. One detective experienced throat/eye irritation in the basement.
During the warrantless walk-throughs (they searched rooms but did not open containers or drawers), detectives observed items they believed consistent with small-scale methamphetamine production. Fire personnel and a meth expert were summoned; no immediate explosive risk was found.
Police then obtained a warrant based on those observations, executed it, arrested Tuschall when he arrived, and later obtained Miranda waivers and inculpatory statements at the station.
The motion judge granted suppression of the physical evidence seized under the warrant and of Tuschall’s statements, concluding the warrantless entries were not justified by the emergency aid exception and the statements were fruit of the unlawful entry.
The Commonwealth appealed; the Supreme Judicial Court affirmed the suppression orders.

Issue	Commonwealth's Argument	Tuschall's Argument	Held
Whether the initial warrantless entry was justified under the emergency-aid exception	Entry was justified because the odor posed danger to residents and the girlfriend might be inside and at risk	Entry was unreasonable: odor and delay did not create an objectively reasonable belief of imminent danger or explosion	Not justified: facts did not support objectively reasonable belief of imminent risk or need for prompt intervention
Whether the second warrantless entry (after observing paraphernalia) was justified to assess danger	Observations of paraphernalia supported a reasonable belief of meth lab risks (explosion) justifying re-entry	Observations did not amount to a reasonable belief of active, explosive danger; second entry flowed from unlawful first entry	Not justified: first-entry observations did not create an objectively reasonable basis for an emergency re-entry
Whether Tuschall’s custodial statements were admissible despite unlawful entry	Statements were voluntary, Miranda waivers were given, and any taint was attenuated by time and police procedures	Statements were fruit of the unlawful entry/arrest; imprisonment and lack of intervening events left taint unpurged	Suppressed: statements were not sufficiently attenuated from the unlawful searches and arrest; exclusion required to deter misconduct
