San Pablo Man Arrested by County Sheriffs Office for Possession of Child Pornography

Press Release


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.
