Phillip Garrido, the man accused of keeping Jaycee Lee Dugard concealed in his backyard for 18 years, is not linked to a wave of murders of prostitutes in the same area in the 1990s, investigators now say. Authorities scoured Dugard's sadistic compound—as well as a neighbor's yard looking for evidence—but essentially turned up nothing. Investigators did say they found a bone fragment—though they were unsure whether it was human—along with other objects that will need further examination before they can be ruled out as evidence. Meanwhile, Garrido's wife, Nancy, is described by her lawyer as unstable and "seems a little lost." It appears likely her defense will portray her as being under Phillip's spell for years.
