Omaha Man Sentenced for Possession of Child Pornography

For Immediate Release
U.S. Attorney's Office, District of Nebraska

Acting United States Attorney Jan Sharp announced the Corey J. Collmann, 38, of Omaha, Nebraska, was sentenced today in federal court in Omaha for possession of child pornography. Chief United States District Judge Robert F. Rossiter, Jr. sentenced Collmann to 48 months’ imprisonment. There is no parole in the federal system. After his release from prison, Collmann will begin a 5-year term of supervised release and will be required to register as a sex offender.

An investigation conducted by the Omaha FBI's Child Exploitation and Human Trafficking Task Force determined that between September 30, 2017 and October 2, 2017, Yahoo! Inc., a company located outside the State of Nebraska, identified multiple images of minors engaged in sexually explicit conduct that were uploaded using one of their services, known as Flickr. 

Yahoo! Inc. provided to law enforcement the account, an email address, and IP address, of the user who uploaded the images of the minors engaged in sexually explicit conduct.  The FBI obtained information related to the IP addresses, which ultimately identified Collmann’s residence in Omaha, Nebraska. 

On February 23, 2018, the FBI executed a search warrant of Collmann’s residence and seized his cellular phone and a tablet.  Forensic analysis of the devices identified approximately 50 images of minors, at least one as young as 3 years old, engaging in sexually explicit conduct.

At the time of the search warrant, Collmann admitted to law enforcement that he used the Yahoo! Inc. Flickr application and that he had viewed child exploitive images. 

This case was brought as part of Project Safe Childhood, a nationwide initiative to combat the growing epidemic of child sexual exploitation and abuse launched in May 2006 by the Department of Justice. Led by United States Attorneys’ Offices and the Criminal Division's Child Exploitation and Obscenity Section (CEOS), Project Safe Childhood marshals federal, state and local resources to better locate, apprehend and prosecute individuals who exploit children via the Internet, as well as to identify and rescue victims.
