Child Porn Tip Leads Police To Sonoma County

ROHNERT PARK-COTATI, CA — Rohnert Park detectives arrested a man suspected of having child sexual abuse porn after a months-long investigation that began with a cybertip, police said.

Uriel Leobardo Ruiz Altamirano, of Rohnert Park, was arrested Wednesday on suspicion of violating the California law that makes it a crime to knowingly possess or control child pornography or obscene material depicting minors — Penal Code § 311.11(a)(1), according to the Rohnert Park Department of Public Safety.

The investigation began in February after the department received a tip from the National Center for Missing and Exploited Children through the Silicon Valley Internet Crimes Against Children Task Force, police said in a news release.

Detectives identified Ruiz Altamirano through follow-up investigation and served multiple search warrants tied to electronic accounts connected to the case, according to the department.

On Wednesday, Rohnert Park officers served a residential search warrant, and an arrest warrant that allows law enforcement to seek a judge’s approval for an arrest before prosecutors have filed formal charges. Police may request one, called a Ramsey warrant, when they believe they have probable cause that a person committed a crime.

Officers took Ruiz Altamirano into custody the same day and booked him into the Sonoma County Main Adult Detention Facility. Bail was set at $90,000.

Anyone with information related to the case should contact Detective Sergeant Quinn at 707-588-3514 and reference case number 26-1193.
