The specific details of the tests are not yet known. County officials said there is no record of any complaints filed over health code violations at the Garrido home on Walnut Avenue in unincorporated Antioch, California.
Code officials also did not receive any complaints about possible living conditions of the back yard, where a hidden layer of tents, sheds and outbuildings was revealed last week as the location where Jaycee Dugard had been kept since her 1991 kidnapping. The Garridos are charged with her kidnapping and rape.
According to Sherif's spokesperson Jimmy Lee, a bone fragment, discovered by investigators on Monday excavating a neighboring home believed to have been under Garrido's supervision at some point when it was vacant, will be sent to experts to determine if it is animal or human.
Garrido has a long history of crimes, beginning with a rape in 1972. He is also a registered sex offender. It is hard to say what the bone fragment might have came from.
