The Supreme Court of Arizona recently issued an opinion in a defendant’s appeal of his conviction based on an illegal search and seizure. The case focused on whether law enforcement must obtain a search warrant in cases involving Arizona criminal defendant’s Internet Protocol (IP) addresses or subscriber information the user provides to an Internet Service Provider (ISP).
In this case, an undercover detective joined an internet forum seeking users interested in child pornography. A user responded and requested to be added to the group. After the detective added him, the defendant sent illicit photos and videos depicting child pornography. Federal agents served a subpoena to obtain the user’s IP address. After obtaining the IP address and ISP, the detective retrieved the name, addresses, and phone number of the defendant. Law enforcement executed a search warrant and confiscated the defendant’s external hard drive, laptop, desktop computer, and cell phone. An in-depth search of these items revealed child pornography and messages the defendant sent to the law enforcement officer.
After he was indicted, the defendant moved to suppress the subscriber information and all evidence seized from his residence. He argued that it was an illegal search and seizure under the Fourth Amendment to the United States Constitution (US Constitution) and article 2, section 8 of the Arizona Constitution (AZ Constitution). He argued that the US Constitution and AZ Constitution require a warrant or court order to obtain his IP and ISP information. The trial court denied his motion, and a jury convicted the defendant on all counts. The court of appeals affirmed the conviction.
