Multiple Search Warrants Served in San Rafael

On Wednesday, May 29th the San Rafael Police Department Investigations Unit served five search warrants in San Rafael, Ca.  Three of these warrants were in the city limits and two of them were in unincorporated San Rafael.  These warrants were the culmination of a multi-jurisdictional investigation into subjects who possess child pornography.

The Silicon Valley Internet Crimes Against Children Task Force (SVICAC) is the point of contact for SRPD to receive information about people who trade and possess child pornography in San Rafael.  The SVICAC helps state and local law enforcement agencies develop an effective response to technology-facilitated child sexual exploitation and Internet crimes against children. This support encompasses forensic and investigative components, training and technical assistance, victim services, prevention and community education. (http://www.svicac.org/)

During the past month, SRPD received information about multiple subjects living in San Rafael who might possess child pornography.  Based on that information, search warrants were obtained by San Rafael Detectives and on May 29th, 2019 these warrants were executed by Peace Officers from the San Rafael Police Department, the Marin County Sheriff’s Department, the SVICAC, the Contra Costa County Internet Crimes Against Children Task Force, the Santa Clara County Sexual Assault Felony Enforcement (SAFE) Team, the Morgan Hill Police Department, Livermore Police Department, and Special Agents from the Department of Homeland Security Investigations Team, the Federal Bureau of Investigations, and the United States Secret Service all participated in these warrants.  At each residence, electronics were seized and forensically examined to determine whether or not child pornography was present on those devices.  These devices will be sent to the Northern California Computer Crimes Task Force for further investigation.

Based on these warrants and subsequent investigation, SRPD arrested the following:

Lorenzo Tziquin Tambriz, a 30 year old resident of San Rafael for Possession of Obscene Material of a Minor. (311.11(B) PC)

John Cazier Blecka, a 64 year old resident of San Rafael for Sending/Selling Obscene Material of a Minor under 18 (311.1(A) PC) and Possession/Distribution of Material Depicting Sex with a Minor under 18 (311.2(C) PC.

There are additional cases under investigation and there is the potential for future arrests in these additional cases. 

In today's technological world, the Internet is a lifeline for most. While it has enhanced the lives of many, it also has made innocent people, especially children, easy targets for predators. The Internet has become a place where predators can reach innocent children without many of the risks of getting caught if they were to target them in person. Every year children are starting to use the Internet and computers at a younger and younger age.

Children are often times trusting, naive, curious, and eager for attention, making them more vulnerable to predators that will target them online in order to take advantage of them. According to the National Center for Missing and Exploited Children, less than 5% of parents are aware of online sexual exploitation and even fewer think their child is at risk. It is important for parents, law enforcement and society as a whole to know of the dangers children face on the Internet and how to reduce the risks of being victimized.
