The Contra Costa County Office of the Sheriff recently received a tip regarding a person who was allegedly in possession of child pornography. Detectives started an investigation and later obtained search warrants for the suspect’s home and computers/electronic devices.
On November 20, 2018, Detectives arrested 34-year-old Francisco Perez of San Pablo. He was booked into the Martinez Detention Facility on one count of possession of child pornography. Perez has since been released pending further investigation.
Perez was previously employed by a food service company that provided food to San Domenico School in San Anselmo. At that time, he used the false name of Mario Arguetta. There is no evidence to suggest any student has been a victim.
The investigation is ongoing. Anyone with any information on this case is asked to call the Contra Costa Sheriff’s Office or the Marin County Sheriff’s Office.
