Earlier this year, a state appellate court issued an opinion in an Arizona homicide case discussing the propriety of the prosecution’s use of cell location site information (CLSI) taken from the defendant’s cell phone. Ultimately, the court reviewed recent Supreme Court case law, concluding that the prosecution’s use of the CLSI data did not violate the defendant’s constitutional rights, affirming his conviction.
The Facts of the Case
According to the court’s opinion, a man was shot and killed outside a club as he sat in his car. Evidently, he was talking to a woman, CK, when two men walked up and shot the man. Police retrieved the cell phones of several witnesses, including CK. During their investigation, detectives discovered that one of the witnesses was in contact with a phone number that belonged to the defendant.
Police officers presented a judge with an ex parte order, seeking to obtain the defendant’s cell phone records. The court signed the order, noting that there was probable cause to believe that the information requested would be relevant to the crimes. Detectives used the information provided by the defendant’s cell carrier to link him to the crime. The defendant filed a motion to suppress, arguing that the CLSI information was illegally obtained without a warrant. The trial court denied the defendant’s motion, finding that the request was supported by probable cause. The jury convicted the defendant of murder, and the defendant appealed.
