CONCORD (KRON) –  A spokesperson with the California Department of Corrections and Rehabilitation tells KRON 4 that they’re conducting a “top to bottom review” of how Phillip Garrido’s parole was handled.

Garrido is chaged with kidnapping and raping Jaycee Lee Dugard 18 years ago.

Officials say a Concord-based parole agent made routine visits to Garrido’s Walnut Avenue Home in Antioch. Until last week, however, the agent was unaware that he had two daughters, who he allegedly had with Dugard.

The parole agent reportedly visited Garrido at least twice a month. While specific details about the home visits are being withheld, so as not to jeopardize the prosecution of the suspect and his wife Nancy, authorities say agents usually make both announced and unannounced visits. Parolees are also required to visit the Concord parole office.

As an 11-year-old, Dugard was snatched from a bus stop in South Lake Tahoe. Now 29, she was reunited with her family last week.

Authorities say she bonded with her kidnappers and helped manage the suspect’s printing business. Dugard and the two girls, now 11 and 15, were allegedly kept hostage in a soundproof shed in Garrido’s backyard.

Garrido and his wife, Nancy, have pleaded not guilty to the abduction, rape and imprisonment of Dugard.
