Mountain View man arrested in connection with child pornography case

A Mountain View man was arrested after an extensive investigation revealed he was connected to a child pornography collection that contained over three hundred images and videos of children as young as six months old being victimized by adults.

In August, Mountain View cybercrime detectives received a tip from the National Center for Exploited and Missing Children regarding multiple suspected child pornography images that had been shared on an individual’s Tumblr page, a social media site that allows users to share photos, videos and other content to a person’s page or blog. Through their investigation, our detectives confirmed that the images were, in fact, pornographic in nature. 

As they began to further investigate who the Tumblr account belonged to, detectives discovered a Dropbox account that contained over 300 additional videos of children, some as young as six months old, being sexually victimized by adults. It appeared that the owner of these accounts not only possessed the videos, but may have been sharing them as well. 

Through a series of search warrants, detectives learned that both accounts, as well as an email address associated with them, belonged to 31-year-old Marco Cordoba Alfaro. 

Around 7 a.m. on Thursday, Dec. 20, Mountain View police detectives, with the assistance of the Silicon Valley Internet Crimes Against Children (SVICAC) Task Force, executed a search warrant at Alfaro’s home, where additional child pornography images were discovered. Alfaro was arrested without incident that same day at his place of work in San Jose. 

Alfaro was booked into the Santa Clara County Jail on suspicion of possession of child pornography and distribution of child pornography. 

“This case is heartbreaking. It’s unconscionable that any child anywhere is victimized and we will do all we can to ensure that justice is served,” said Lt. Mike Canfield. “We appreciate the teamwork on this case, both internally and with our law enforcement partners.”
