SAN FRANCISCO — After a month-long investigation by the San Francisco Police Department’s Internet Crimes Against Children Unit, a man was arrested Tuesday, June 30 on suspicion of having cyber sex with underage girls and producing child porn, among other digital- and internet-related sexual crimes involving minors.
Juan Crisanto-Ramirez, 35, was arrested at his home on the 300 block of Capp Street in San Francisco’s Mission District after investigators searched his home, and found dozens of child porn videos on his laptop. Some of the videos depicted pubescent and prepubescent children performing sexual acts, while others showed young children having sex with adults, police said.
Police obtained a search warrant after an investigation by the SFPD’s Internet Crimes Against Children Unit (ICAC) found that Crisanto-Ramirez had been having sexually explicit “chats” (cyber sex) with underage girls via various “messenger applications” and “social media sites,” police said. Investigators declined to specify which sites Crisanto-Ramirez was using, fearing that would “compromise the [Crisianto-Ramirez] case and other cases,” police spokesperson Carlos Manfredi said in an email.
Crisianto-Ramirez has been charged with distribution of child pornography, possession of more than 600 images of child pornography, sending harmful material to a minor, and production of child pornography, all of which are felonies. Crisanto-Ramirez is not a registered sex offender in California, according to Megan’s Law. And he has no prior rap sheet, according to available records.
The ICAC investigation of Crisianto-Ramirez is ongoing, police said. ICAC is a nationwide task force that has been working with the San Francisco Police Department to investigate and prosecute suspects involved in such activity. “It’s a one stop shop involving the DA, investigating officers, and IT technicians,” Officer Manfredi said. “They all work together, so that the job gets done.”
