Massachusetts limits a search incident to arrest by statute, and that limit is narrower than what the Fourth Amendment allows. A Supreme Judicial Court decision issued July 17, 2026 enforced it against Boston officers who searched a handcuffed woman repeatedly to find her car key, then used the key to open her locked glove compartment. Commonwealth v. Dobson, SJC-13794, reversed the denial of her motion to suppress the firearm and pills inside, and it reaches into how many Massachusetts gun charges are built out of an ordinary traffic stop.
A search incident to arrest is a warrantless search of someone under arrest. General Laws c. 276, § 1 allows one for only two purposes: seizing evidence of the crime of arrest, and removing a weapon the arrestee might use to resist arrest or escape. Evidence from a search serving neither purpose is inadmissible under the statute’s own terms.
A Roxbury Traffic Stop and a Locked Glove Compartment
Boston officers patrolling Nubian Square in August 2022 stopped a car for window tinting that appeared to violate G. L. c. 90, § 9D. An officer saw the front passenger push something toward the console. Both occupants were ordered out, and a patfrisk of the driver produced marijuana but no weapon.
When an officer found the glove compartment locked, he asked for the car key. The driver refused, and after a struggle officers handcuffed her and arrested her for assault and battery on a police officer. They then searched her repeatedly for the key, the last search reaching under her shirt and along her waistband. No key turned up.
A police dog then alerted to firearm evidence in the glove compartment. Officers told the driver the car would be towed and pried open without the key. She produced it from the back of her shorts, and the compartment held a firearm and pills.
The Crime of Arrest Sets the Outer Limit of the Search
The arrest was for assault and battery on a police officer, and that fixed what any search incident to it could look for. Evidence of the assault would have to be something concealed on her person, and the court found it difficult to conceive what that would be. Disarming her did not fit either, because the first patfrisk had already turned up no weapon and nothing renewed a safety concern once she was in handcuffs.
The record showed a search aimed at a different crime. Officers asked for the key before, during, and after the searches, and said out loud why they wanted it. One reported to his supervising sergeant that they were “looking for the keys to get into the glove [compartment],” and a second directed the deepest search of all. Under Commonwealth v. Blevines, 438 Mass. 604 (2003), a search made for an investigatory purpose unrelated to the crime of arrest falls outside G. L. c. 276, § 1.
Justice Georges wrote separately about body-worn camera footage, and the point is a practical one for any Suffolk County suppression hearing. Recordings do more than corroborate an officer’s testimony. They capture what officers said and directed while a search was underway, and those statements are conduct rather than hidden motive, so a judge can use them to determine the objective purpose of the search.
Handing Over a Key Was Not Valid Consent
The Superior Court judge found the searches unlawful and still denied suppression, reasoning that the driver consented to the glove compartment search when she surrendered the key. If your case turns on something you gave police after they pressured you for it, the burden of justifying that sits with the Commonwealth, not with you.
When consent follows an unlawful search, the Commonwealth must show the taint has dissipated. Courts weigh three things: how much time passed, whether anything intervened, and the purpose and flagrancy of the police misconduct. About three minutes separated the most invasive search from the handover, with officers pressing her the whole time. The dog alert and the tow warning did count as intervening events. The searches themselves, though, had been run to get the key that would open the glove compartment, which is the shortcut the exclusionary rule exists to deter.
The motion judge had stopped after the first two factors. The SJC made clear that the purpose and flagrancy of police misconduct bear on whether a later consent is valid, and on this record the Commonwealth had not carried its burden. Patrick J. Murphy has defended criminal cases in Massachusetts since 1994, and a motion to suppress a gun found in a car is a routine part of that work in Suffolk County.
