Commonwealth v. McCarthy
Annotate this Case
Two detectives from the Lowell police department, while investigating a home invasion in Lowell, Massachusetts, crossed into Nashua, New Hampshire, to speak with the defendant. During the conversation, one detective suspected the defendant was deleting data from his cell phone and seized it without a warrant. The detectives then brought the phone back to Massachusetts and obtained a warrant to search it.
In the Superior Court, the defendant moved to suppress the evidence obtained from the cell phone, arguing that the seizure was unlawful. The motion judge allowed the motion, finding that the Lowell detectives had no authority to seize the phone in New Hampshire. The Commonwealth sought an interlocutory appeal, which was allowed by a single justice of the Supreme Judicial Court for the county of Suffolk. The case was then transferred to the Supreme Judicial Court on its own initiative.
The Supreme Judicial Court of Massachusetts reviewed the case and concluded that the Lowell detective did not have extraterritorial authority to seize the cell phone in New Hampshire. The court found that no statutory or common law authority permitted the warrantless seizure in these circumstances. The court also rejected the Commonwealth's argument that the evidence would have been inevitably discovered, as this theory was not sufficiently supported by the record. The court held that suppression of the evidence was the appropriate remedy to deter police misconduct and preserve judicial integrity. The order allowing the motion to suppress was affirmed.
