Edgar Covarrubias-Padilla, a night manager and counselor at the popular science camp for kids, was arrested May 7th on child pornography charges. Prosecutors filed additional charges against the 27-year-old, known to kids as “Papa Bear”, including committing a lewd and lascivious act on a child under the age of 14 and production and distribution of child pornography.

Santa Clara County Sheriff James Jensen stresses the workers are low-level offenders, convicted of DUI or minor drug offenses. He said the inmates perform custodial duties or lawn maintenance/landscaping duties.

Covarrubias-Padilla was a trained work-furlough supervisor, who according to Jensen, attended an eight-hour class required once a year as a part of his training.
