In today’s rapidly advancing technological landscape, law enforcement agencies and prosecutors have access to a growing array of tools and methods to investigate and gather evidence. With the advent of artificial intelligence and sophisticated data analytics, traditional methods of crime-solving are being supplemented and often surpassed by new digital techniques. However, as technology progresses, legal protections against search and seizure sometimes struggle to keep pace. Courts are continually called upon to interpret and establish what types of warrants and legal processes are required to obtain different forms of digital evidence. Recently, the Supreme Judicial Court of Massachusetts addressed these issues in an appeal where the defendant argued that his location and cell phone ping data were unlawfully obtained and used to convict him.
The case in question was filed after an apparent murder in 2012. On that day, the defendant allegedly shot and killed a woman in her car in Fall River, Massachusetts. The victim’s body was discovered in her vehicle, with evidence of a robbery gone wrong. She had been carrying drugs, which were found both on her person and beneath her body. The victim’s cell phone was notably missing from the scene, setting the stage for the digital trail that would later play a crucial role in the investigation.
To track down the defendant, police relied heavily on data from the victim’s phone. The call logs revealed a phone number linked to the defendant, indicating that he had been in contact with the victim shortly before her death. The defendant, identified through his call history, was found to have made a call to the victim just before the shooting. Through further investigation, including witness statements and physical evidence such as a bloodstained T-shirt and a handgun found in the defendant’s possession, the case against him began to build. The defendant filed motions to suppress the cell phone records and related data, arguing they were obtained without a proper warrant, but these motions were denied. Ultimately, the defendant was convicted of first-degree murder based on the theory of felony murder, with armed robbery as the underlying felony.
