119 N.E.3d 257
Mass.2019Background
- Lawrence police responded to an anonymous 911 tip that a caller "saw two Spanish guys" load a handgun and enter a multiunit building at 5–7 Royal Street. The caller gave her address and later spoke to an officer by phone.
- Officers learned there had been recent home-invasion activity in the city (general ongoing investigation), but had no information tying those incidents to this address.
- Officers encountered no signs of forced entry or disturbance; residents of unit 7A reported seeing/hearing nothing.
- An officer at the rear observed Wascar Diaz (Hispanic, facial hair, black/gray sweater) exit and then quickly reenter and close a rear door when challenged; the door was later found locked.
- Within minutes, officers entered unit 5A without a warrant, conducted a protective sweep and a basement search, observed apparent contraband in plain view, then obtained a warrant and conducted a full search.
- The Superior Court granted the defendant’s motion to suppress; the Appeals Court reversed; this Court affirmed the suppression, holding the warrantless entry/search was unjustified.
Issues
| Issue | Commonwealth's Argument | Arias's Argument | Held |
|---|---|---|---|
| Whether entry/search fit the emergency-aid exception | Officers reasonably believed immediate aid or danger existed based on tip that men loaded a gun and a man was seen retreating into the building | No objectively reasonable basis for emergency: no signs of violence, no persons known to be in unit 5A, and caller’s tip lacked corroboration | Entry/search not justified under emergency-aid exception; totality did not support objectively reasonable belief of emergency |
| Whether officers had exigent circumstances + probable cause to enter without warrant | Tip plus retreating man and knowledge of home-invasion rash supplied probable cause and exigency (risk to safety/evidence) | No exigency: no signs of violence, building secured by surrounding officers, no reason to think evidence would be lost; no probable cause because caller’s reliability was not corroborated | No exigency and no probable cause under art. 14; warrantless entry unjustified under exigent-circumstances doctrine |
| Reliability of 911 tip (Aguilar‑Spinelli framework) | Caller was identifiable (gave address), contacted by police, used specific detail ("racking")—supporting veracity and basis of knowledge | Caller provided conflicting details, said entry was "easy" (likely had key), was new to neighborhood—undermining reliability; required police corroboration | Basis-of-knowledge satisfied (firsthand observation) but veracity insufficiently corroborated; overall tip unreliable enough that probable cause not established |
| Scope of search and plain-view seizure | Protective sweep and limited inspection were reasonable to locate potential victims/suspects; contraband plainly visible and lawfully seized | Even if limited, sweep was unjustified because entry lacked lawful basis; plain-view seizure invalid if arrival at vantage point was unlawful | Because initial entry was unlawful, subsequent sweep and seizures cannot be upheld under emergency-aid or exigent exceptions |
