Authorities have hauled away dumpsters full of trash and debris along with potentially damning evidence from the property of Jaycee Dugard's accused kidnappers, but authorities say they found no definitive sign of two other missing girls.
Police from Hayward and Dublin, Calif., have been leading an intensive search of Phillip and Nancy Garrido's Antioch, Calif., property since last week after deciding there were enough similarities between Dugard's kidnapping and the disappearances of 9-year-old Michaela Garecht and 13-year-old Ilene Misheloff.
But Phillip Garrido is still considered a potential suspect in both abductions and authorities are now tasked with combing through several items removed from his home and backyard including clothing, photos and Garrido's writings.
A bone fragment found earlier in the search was found to likely be a human tooth, though judged too old to be relevant in either case. More labwork has been ordered.
Phillip Garrido is being held on $30 million bond. Nancy Garrido's lawyer has not requested bail. Both have pleaded not guilty to 28 counts, including kidnapping and rape, in the Dugard case.
Police have said there were several similarities between Dugard's 1991 kidnapping and the others, including method of abduction. And the grey Ford sedan impounded from the Garrido's lot matches witness descriptions in all three abductions.
Michaela Garecht was yanked into a car in 1988 after she and a friend took their scooters to the corner store, the first time they'd been allowed to do so on their own.
That friend, Katrina Rodriguez, told "Good Morning America" earlier this month that she recognized something in Garrido's eyes when she saw him on television after Dugard was found.
"I see that same intensity," Rodriguez said. "That creepy look that I don't think I'll ever forget."
Ilene Misheloff's January 1989 disappearance was not as brazen, but witnesses have reported seeing a similar car in the area around the time she vanished while taking a shortcut home from school.
Jaycee Dugard Questioned on Other Cases, Misses Her Pets
Dugard, authorities have said, has also been questioned about the other missing girls, but her answers did not yield conclusive information.
She did, however, say that she missed one aspect of her 18 years in captivity -- her pets.
Contra Costa County animal services Lt. Joe DeCosta told the Associated Press last week that an advocate of Dugard has indicated that she wants her five cats, two dogs, three cockatiels, a pigeon and a mouse back in her possession.
DeCosta said the animals were taken into custody when police arrested the Garridos and Dugard and her two children allegedly fathered by Phillip Garrido were reunited with her mother. The animals were placed in temporary foster homes.
The pets were in good condition, DeCosta said, and officials were working on reuniting them with Dugard.
Last week, Hayward Police. Lt. Chris Orrey, whose department is investigating Michaela's kidnapping, said the Garridos had not yet een interviewed by police in the other two cases as there was still work to be done relating to the search.
Cadaver dogs "indicated" at a spot in the backyard Thursday and archaeological dogs were brought in to search for older bones.
"We have recovered numerous pieces of evidence that we want to look closer at and examine," Dublin Police Lt. Kurt Von Savoye said.
Though the lack of hard evidence doesn't give the families closure they want, Orrey said, it could mean the girls are alive somewhere.
"It's a mixed blessing either way," she said. Both lieutenants said that if it turns out the Garridos were not involved with the girls' abductions, they hope the attention brought to their cases will yield tips that could lead to a resolution.
Orrey said the search could continue into next week, though it will be suspended over the weekend both to cut costs and to give investigators a much needed break.
Family Moves On
"Jaycee, her daughters, and I are grateful for everyone's generosity, kindness, and good wishes these past few weeks," Terry Probyn said in a statement provided to ABC News by former U.S. attorney McGregor Scott. "Thank you. All of us are doing very well under the circumstances. We especially appreciate everyone recognizing that what we need most right now is to be allowed to become a family again within a zone of privacy and security. We hope that our story focuses attention on all of the children still missing, and on their need to be found. We must keep looking for them. As Jaycee shows, miracles can happen."
A trust fund for Jaycee Dugard was set up following her rescue, the address for which is below.
