United States v. Stanley
Erdely was investigating online distribution of child pornography when he discovered a computer on a peer-to-peer network sharing 77 files that he suspected contained child pornography. With information available to anyone, he found the Internet protocol address (IP address) through which it connected to the internet. Searching publicly available records, Erdely determined that the IP Address was registered to a Comcast subscriber and obtained a court order. Comcast gave Erdely the Neighbor’s name and Pittsburgh address. Erdely executed a warrant. None of the Neighbor’s computers contained child pornography or the file-sharing software; his wireless router was not password-protected. Erdely deduced that the computer sharing child pornography was connecting without the Neighbor’s knowledge. With the Neighbor’s permission, Erdely connected a computer to the router for remote access. Later, while working in Harrisburg, Erdely learned that the computer was again sharing child pornography on the Neighbor’s IP address. Erdely determined the mooching computer’s IP address and MAC address, which belonged to an Apple wireless card. Erdely had not discovered any Apple wireless devices in the Neighbor’s home, so he decided to use a “MoocherHunter” mobile tracking software tool, which can be used by anyone with a directional antenna. Not knowing which residence the signal was coming from, Erdely proceeded without a warrant. From the sidewalk the MoocherHunter’s readings were strongest when aimed at Stanley’s apartment. Erdely obtained a warrant for Stanley’s home. When officers arrived, Stanley fled, but returned and confessed that he had connected to the Neighbor’s router to download child pornography. Erdely seized Stanley’s Apple laptop and recovered 144 images and video files depicting child pornography. Stanley was charged with possession of child pornography, 18 U.S.C. 2252(a). The district court denied a motion to suppress. The Third Circuit affirmed. Use of the MoocherHunter was not a search under the Fourth Amendment. View "United States v. Stanley" on Justia Law
