Milwaukee Man Sentenced to 40 Months in Federal Prison for Possessing Child Pornography

Matthew D. Krueger, United States Attorney for the Eastern District of Wisconsin, announced that on October 3, 2018, Oscar Chaves (55 years old) of Milwaukee, Wisconsin, was sentenced in Federal Court to 40 months in prison after pleading guilty to possessing child pornography contrary to Title 18, United States Code, Sections 2252A(a)(5). After his release from prison, Chaves will spend 5 years on supervised release.

Chaves used the Gigatribe computer program to access and download child pornography, as well as to engage in highly sexualized chats with other users about their affinities for child pornography. Gigatribe is a peer-to-peer file-sharing network that establishes private network connections between users. FBI agents investigating child pornography crimes on Gigatribe obtained and executed a search warrant at Chaves’s residence in Milwaukee. During the search, FBI agents found computers, removable hard drives, and DVDs that together contained more than 6,000 images and videos of child pornography.

While handing down the sentence, United States District Judge Pamela Pepper emphasized the seriousness of the offense and the importance of protecting children from sexual exploitation. Judge Pepper noted that victims of child sexual abuse continue to suffer knowing that people like Chaves actively seek out and collect images of their abuse.

This case was investigated by the FBI. The case was prosecuted by Assistant United States Attorney Benjamin W. Proctor.

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 U.S. Department of Justice. Led by U.S. Attorneys’ Offices and the 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.
