MARIPOSA, Calif. (KSEE/KGPE) – A 42-year-old man was arrested Sunday on suspicion of the possession and distribution of multiple files of child pornography, according to the Mariposa County Sheriff’s Office.

Officials say Charles “Chuck” Harris, of Greeley Hill, was taken into custody following a series of tips generated by the National Center for Missing and Exploited Children (NCMEC), which prompted three investigations, deputies say.

According to the City of San Leandro, Harris was a firefighter/paramedic with the Alameda County Fire Department.

The city says that Harris is now on paid administrative leave as a result of his collective bargaining agreement, which is standard for employees with the Alameda County Fire Department.

These allegations, if proven true, are deeply concerning and undermine the public’s trust in our public safety service. We will work closely with our partner agencies to ensure that justice is served. Each day, our community places its trust in our public safety staff, and we absolutely understand the anger and disappointment caused by the arrest of a first responder.

Members of the Mariposa County Sheriff’s Office, Central California and Silicon Valley Internet Crimes Against Children (ICAC) Task Forces, and the Federal Bureau of Investigation (FBI), executed the search warrants in Mariposa and Alameda Counties.

Charles was arrested on a Ramey warrant for possession of child pornography and booked into the Mariposa County Adult Detention Facility, according to officials.

“The safety and protection of children is one of the most important jobs we have, children need to know they are safe. I am extremely proud of the swift and professional job our detectives and partner agencies did, always working together so our communities are safer,” says Sheriff Jeremy Briese.
