SARATOGA — A resident and employee of the Walden West science camp was arrested Thursday after sheriff’s deputies found hundreds of images and videos of child pornography on the man’s personal computer, officials said.

Edgar Covarrubias, 27, had “several hundred” photos and videos on his personal computer and phone, according to the Santa Clara County Sheriff’s Office.

Homeland Security officials had tipped off the sheriff’s Sexual Assault Felony Task Force about Covarrubias, whose name came up as part of an investigation into people trading child pornography online.

Covarrubias was arrested on charges of possession of child pornography, according to the Sheriff’s Office, and booked into Santa Clara County Jail.

Covarrubias has been an employee at Walden West science camp since August 2013. Covarrubias has been removed from his position as substitute recreation assistant and evening facilities monitor, Santa Clara County Office of Education spokesman Ken Blackstone said in a news release.

The office is cooperating fully with law enforcement, Blackstone added.

When hired, Covarrubias was subject to a standard background screening for employment, including fingerprint clearance from the Department of Justice, according to Blackstone.

The camp is a county education program that provides science and environmental education and outdoor school events to mainly fifth- and sixth-graders. It operates at two sites, one in Saratoga and the second in Cupertino.

Santa Clara County Superintendent of Schools Jon Gundry said Covarrubias had previously worked at the Foothills Tennis and Swim Club and at YMCA Camp Campbell. He also worked for the Santa Clara Unified School District 10 years ago for one summer, Gundry added.

“We have not had any complaints (about Covarrubias),” Gundry said late Thursday.

Gundry said that before Covarrubias was fired Thursday after his arrest, he lived on the property with four other employees in a small cabin and that none of his jobs required him to interact with any of the students at the camp.
