Police are returning to the home of Jaycee Dugard's alleged kidnappers Friday to continue combing the property and removing debris, as new details emerge about Phillip and Nancy Garrido, who police say lived on a filthy property littered with piles of garbage, hazardous wiring and an open septic hole.

Newly released photos taken by inspectors revealed the filth and waste that filled the home.

Among the violations reportedly found that were listed by inspectors were "hazardous wiring used for occupancy, piles of garbage, refuse, discarded furniture, discarded appliances, yard cuttings, cardboard boxes and barrels, discarded personal and household items, improperly stored non operational vehicles, vehicle parts, tarps, plastic and metal buckets, open septic hole and outside toilet that is not connected to a sewer or septic system."

Once the debris — including a shed, slabs of concrete, and piles of garbage — is cleared, police will bring dogs in who are trained to locate human bones that might be buried throughout the property.

The Contra Costa Times reported Phillip Garrido's mother, who is the registered owner of the home, was ordered to clean up the property before county officials conduct a cleaning at her expense.

Meanwhile, authorities said Thursday that cadaver dogs picked up a scent that could indicate buried remains in the backyard of the Garridos.

Alameda County Sheriff's Department spokesman Sgt. J.D. Nelson said two dogs "indicated" on a site in their backyard. But he cautioned that the area is known to have buried remains from Native Americans and animals.

The Garridos are charged with the 1991 kidnapping of Jaycee Dugard, who was snatched outside her South Lake Tahoe home when she was an 11. Prosecutors say the Garridos held her captive in their backyard for 18 years. The couple has pleaded not guilty.
