SJC Upholds Robbery Stop Based on Surveillance Footage and Distinctive Clothing: Commonwealth v. Palmer (SJC-13873, August 10, 2026)

Byron Palmer ran when Boston police approached him in a Jamaica Plain apartment complex parking lot on January 14, 2021. As officers gave chase, he tossed drugs and cash. A jury later convicted him of cocaine possession with intent to distribute. The Supreme Judicial Court affirmed, holding that Detective Allison Eng had reasonable suspicion to stop Palmer based on her review of surveillance footage from a January 2 robbery and her contemporaneous observation of him wearing the same distinctive hat and matching the suspect’s physical description.

The court also clarified when the seizure occurred. Palmer was seized not when officers first approached him, but the moment several officers began pursuing him from multiple directions after he fled. That timing mattered because it determined whether the discarded drugs were fruit of the seizure.

The Robbery and Investigation

On January 2, 2021, a cell phone salesperson met a customer at a Jamaica Plain apartment complex. Inside a residential building, someone robbed the salesperson of two phones. When the victim followed the robber outside to recover the phones, the robber pulled a firearm and fired one shot. The victim described the assailant as a six-foot-one man wearing black clothing and a camouflage mask, speaking with a southern accent.

Detective Eng led the follow-up investigation. She obtained surveillance footage from multiple cameras throughout the complex. The video corroborated the victim’s account and showed the suspect running from the building carrying what appeared to be the stolen bag. Although the suspect wore a face mask, Eng derived a detailed clothing description from the footage.

The suspect wore a distinctive two-toned jacket (black on the bottom, gray on top) with small writing on one arm. He had on sneakers with reflective tape around them. He also wore a black and white checkered hat with a large round logo on the front and a metallic price tag still attached to the brim. Eng described the suspect as dark-skinned with long dreadlocks.

The next day, January 3, a housing authority officer reviewing additional footage spotted someone matching the suspect description in the same hallway. This time the individual was not wearing a mask. The officer sent Eng a still image. Eng watched the corresponding video and identified a person fitting the suspect’s general size, complexion, and hairstyle, wearing what she believed was the same distinctive jacket and sneakers.

On January 14, the housing authority officer was watching surveillance in real time when she saw the same individual. She texted Eng: “Your guy is back,” along with a still image. Eng could see the hat and hairstyle clearly in the image. She decided to respond to the location to attempt to identify the individual.

The Stop

Eng and two other detectives, dressed in plain clothes with visible badges, went to the parking lot outside the building where the robbery had occurred. Because the original incident involved a firearm, four uniformed officers also responded in a police wagon, which they parked in the lot. Eng and the detectives approached from one direction. The uniformed officers, ten to twenty feet away, approached from another.

When Eng saw Palmer in the parking lot, she believed he was the person responsible for the robbery based on his hairstyle, complexion, hat, and size. One of the detectives called out to get Palmer’s attention and information. Palmer immediately ran. Several officers began chasing him. As he ran, Palmer discarded individually wrapped plastic bags and money from his pockets. The pursuit lasted three to four seconds before Palmer stopped, put his hands up, and was detained. Police recovered the discarded items, which were identified as money and cocaine.

The Motion to Suppress

Palmer moved to suppress the drugs, arguing his seizure lacked reasonable suspicion. A Superior Court judge denied the motion, concluding Palmer was not seized until officers apprehended him after his flight. The judge found that at that point, the combination of evidence identifying Palmer with distinctive details and demonstrating his criminality established reasonable suspicion. Because Palmer abandoned the drugs before being seized, the judge ruled their recovery was not a search. A jury acquitted Palmer of armed robbery but convicted him of drug possession with intent to distribute.

The Appeals Court affirmed in a divided opinion. Palmer sought further review.

When the Seizure Occurred

The SJC first tackled the critical question of timing. If police stopped Palmer before he discarded the drugs, the drugs might be fruit of an unlawful seizure. If he was stopped after discarding them, the drugs would not be subject to suppression because he abandoned them.

The court held that Palmer was seized when officers began pursuing him, before he discarded the drugs. Not all police encounters amount to a constitutional seizure. Officers may make noncoercive inquiries without implicating constitutional protections. A seizure occurs when an officer, through words or conduct, objectively communicates that he will use police power to coerce a person to stay.

The court agreed with the Appeals Court majority that it was unnecessary to decide whether Palmer was seized when officers initially approached him. The defendant did not discard the drugs until after he began running and was immediately pursued. Thus, the drugs could be fruit of the seizure whether the precise moment was the initial approach or when officers began chasing him.

Pursuit that appears designed to effect a stop is no less intrusive than a stop itself. Here, after Palmer fled in response to a detective calling for his attention, several officers (both detectives with badges and uniformed officers) began chasing him. Body-worn camera footage showed officers converging on Palmer from more than one direction. This was a show of authority that a reasonable person would consider coercive.

The Commonwealth argued the case resembled Commonwealth v. Franklin, where the court held there was no seizure when police chased a defendant who had fled from an unmarked car before officers got out. The SJC distinguished Franklin on two grounds. First, in Franklin the defendant’s flight was not prompted by anything police did. Here, Palmer fled after officers approached on foot and called out to him. Second, two groups of officers converged on Palmer from different directions within a crowded parking lot, plainly the object of an official assertion of authority.

Reasonable Suspicion Analysis

The court then examined whether officers had reasonable suspicion at the time of seizure to believe Palmer had committed the robbery. Reasonable suspicion requires specific and articulable facts and reasonable inferences from them, in light of officer experience. It requires less than probable cause but more than a hunch. The Commonwealth bears the burden of showing a seizure is supported by reasonable suspicion.

Because the seizure began before Palmer discarded the drugs, the drugs played no role in the analysis. The court looked only to information known to Eng at the time of seizure, not to what the housing authority officer knew, because the Commonwealth presented no evidence that the officer had additional knowledge beyond what Eng possessed.

Before the seizure, Eng had the following information: the victim’s description of the robber as a six-foot-one man with black clothing and a camouflage mask; video footage from January 2 showing a suspect with dark complexion, long dreadlocks, wearing a mask, a black and white checkered hat with a large logo and metallic tag, a black and gray jacket with writing on one arm, and sneakers with reflective tape; a still image and video from January 3 showing an unmasked man with the same size, hairstyle, complexion, and distinct jacket and sneakers; and a still image from January 14 showing an individual with a similar hat and hairstyle in the area where the robbery occurred.

Additionally, when Eng returned to the crime scene twelve days later, she observed Palmer and believed he was responsible for the robbery based on his size, hairstyle, complexion, and the hat he was wearing, which matched the distinctive black and white checkered hat with the large logo and metallic tag.

The defendant argued officers stopped him based on a vague description that could fit many individuals. The court acknowledged its obligation to proceed with caution, noting that matching a broad, general description does not alone amount to reasonable suspicion, particularly if the description could fit many people in the area.

However, this was not a case where police seized someone based solely on a generalized witness description. Eng watched surveillance footage from the day of the robbery to develop her own description. She reviewed video and a still image from the day after the robbery to observe the same suspect without a mask. On the day of arrest, Eng recognized Palmer as the individual who committed the robbery, relying on the suspect’s size, complexion, hairstyle, and the unique features of his hat.

Standing alone, each factor might not suffice to establish reasonable suspicion. Hats are easily worn, taken off, changed, or discarded. Braided hairstyles are not uncommon among Black people. A general description of a Black male is insufficient. However, reasonable suspicion analysis examines the totality of facts, and a combination of factors that are each innocent by themselves may, when taken together, amount to the requisite reasonable belief.

The court noted two additional factual circumstances that added minimal weight to the calculus. First, while flight alone is insufficient to establish reasonable suspicion, it is a factor properly considered in the analysis. Second, the motion judge found the robbery and arrest occurred in a high crime area. While the court has cautioned against relying on that characterization, it can be a factor when there is a direct connection with the specific location and activity being investigated. Here, there was such a connection: Eng testified to a history of robberies, shootings, and calls for violent crimes in the apartment complex, and the crime under investigation took place in the same complex.

Why It Matters

The decision confirms that reasonable suspicion can rest on an officer’s own detailed observations from surveillance footage, not just witness descriptions. When an officer reviews video that shows a suspect’s distinctive clothing and physical characteristics, then later recognizes someone matching that description at the crime scene, the totality of circumstances may support a stop.

The case also reinforces that pursuit by multiple officers converging from different directions constitutes a seizure at the moment the chase begins. Officers cannot avoid Fourth Amendment scrutiny by claiming a defendant was not seized until physically apprehended if the pursuit itself communicated an assertion of authority a reasonable person would find coercive.

Finally, the decision illustrates how courts weigh factors in the reasonable suspicion calculus. No single factor (a hat, hairstyle, skin tone, or presence in a high-crime area) will suffice on its own. But specific, articulable details observed by an investigating officer, combined and viewed as a whole, can meet the constitutional threshold, particularly when the officer develops the description through direct review of surveillance evidence rather than relying solely on second-hand reports.
