A former corrections sergeant at the Central California Women's Facility in Chowchilla has been sentenced to 15 years in federal prison for dealing in child sexual abuse material (CSAM). Ralph Contreras Jr., 40, admitted to receiving and distributing illegal content via social media apps over a four-month period.
According to court documents, between September 29, 2024, and January 2, 2025, Contreras used social media platforms to receive and distribute CSAM. He specifically sought out material depicting prepubescent minors. At the time of his arrest, he was employed as a corrections sergeant at the Central California Women's Facility in Chowchilla.
Contreras pleaded guilty on April 13, 2026. On July 13, 2026, U.S. District Judge Kirk E. Sherriff sentenced him to 15 years in prison for receipt and distribution of child sexual abuse material. The case was prosecuted by Assistant U.S. Attorney Joseph Barton.
The Central California Women's Facility is located in Chowchilla, Madera County. The investigation involved the Madera County Sheriff's Office, highlighting local law enforcement's role in combating online child exploitation.
This case is part of broader efforts by federal and local authorities to crack down on child sexual abuse material distribution. The Central California Internet Crimes Against Children Task Force routinely works with agencies like Homeland Security Investigations to identify and prosecute offenders.
The 15-year sentence reflects the severity of Contreras's crimes and serves as a warning to others who exploit children. Law enforcement continues to urge the public to report suspicious online activity.
