Instead April of 2019, the Massachusetts Supreme Judicial Court issued an important opinion in a Massachusetts drug case discussing whether police officers can use a GPS tracking device to track the location of a suspect without first obtaining a warrant. The court held that police needed to obtain a warrant, and, by failing to do so, anything they recovered as a result of the information obtained was suppressible as “fruit of the poisonous tree.”
According to the court’s written opinion, police officers were in the process of investigating a homicide and obtained the cellular site location information (CSLI) for one of the suspect’s phones. Police suspected that the homicide was drug-related, and that there were several people involved, including the defendant. The cell phone the police tracked was registered to the defendant but used by another individual. However, the police had reason to believe that the defendant would be traveling with the user of the cell phone.
The CSLI data eventually led police to the defendant’s residence, which was a three-story building with multiple rooms available to rent. Police knocked on the door and were admitted into the home. Police eventually made their way up to the third floor, where they encountered the defendant. The police explained that they were investigating a homicide and that they believed the suspect may be in the building. They also mentioned that narcotics were involved. The defendant gave his consent for the officers to enter his room and conduct a search. During the search, the police found $2,200 in cash and two bricks of cocaine. The cocaine was located in a crawl space. The trial court ultimately granted the defendant’s motion to suppress.
