The case began during an online undercover peer-to-peer investigation. Law enforcement identified an internet protocol (IP) address associated with the file-sharing of child pornography. Subsequent investigation showed that this IP address came back to Richter's residence. A search warrant located Richter's laptop and other media, which were found to contain child pornography.
This investigation was conducted by the United States Secret Service, the Davenport, Iowa, Police Department, and the Iowa Internet Crimes Against Children (ICAC) Task Force.
The case was prosecuted by the United States Attorney's Office, Southern District of Iowa.
