Luis Santos Perez, 34, of Las Vegas, was sentenced to 144 months in prison for distributing child pornography through an online chat room known for sharing explicit images of child sexual abuse. The sentencing took place in U.S. District Court in Washington, D.C., as announced by U.S. Attorney Jeanine Ferris Pirro.
Santos Perez, who used the alias “chillbill,” pleaded guilty on February 20, 2025, before Judge Beryl A. Howell to a charge of distribution of child pornography. In addition to his prison sentence, he will serve ten years of supervised release and must pay $42,000 in restitution to victims.
FBI Assistant Director in Charge Darren B. Cox of the Washington Field Office joined the announcement.
The case began when an undercover FBI agent from the Child Exploitation and Human Trafficking Task Force monitored an online chat room where members posted videos depicting minors engaged in sexually explicit conduct. Investigators identified Santos Perez as both a participant and administrator in this group. He posted several clips involving pre-pubescent children and required other members to share similar material or face removal from the group.
“This defendant was both an administrator and participant on a mobile app called KIK where child sexual abuse images were exchanged,” said U.S. Attorney Pirro. “In his role as administrator, he required younger and younger images, including infants, in order to remain in his group. Twelve years is not enough which is why the judge ordered him to serve an additional 10 years supervised release.”
Law enforcement arrested Santos Perez on May 13, 2024, in Las Vegas and seized multiple digital devices containing more than 2,000 images of child sexual abuse materials. During questioning by officers, he admitted sending and receiving such material within two online groups.
The investigation was conducted by the FBI Washington Field Office’s Child Exploitation and Human Trafficking Task Force with participation from federal agents and detectives based in northern Virginia and the District of Columbia. The task force focuses on investigating individuals involved in exploiting children or human trafficking within these regions.
Assistant U.S. Attorney Karen Shinskie prosecuted the case for the District of Columbia.
This prosecution falls under Project Safe Childhood—an initiative launched by the Department of Justice in February 2006 aimed at protecting children from online exploitation and abuse by coordinating resources among federal, state, and local agencies nationwide.
