The couple face a number of charges, including kidnap and rape
Phillip Garrido's wife says she misses the two daughters her husband allegedly fathered with Jaycee Lee Dugard, the girl they are accused of kidnapping.
Nancy Garrido's lawyer, Gilbert Maines, told CBS television that she saw them as family and "loved them very much".
Officials say Mr Garrido fathered Ms Dugard's two daughters, now 11 and 15.
But they have cleared him of links to a series of unsolved prostitute murders after a four-day search of his home in California failed to find any evidence.
The Garridos were arrested last week and charged with the kidnapping, rape and imprisonment of Ms Dugard, who was 11 when she was snatched outside her home in 1991.
They have pleaded not guilty.
Mr Maines, the lawyer for 54-year-old Nancy Garrido, told the CBS Early Show that his client was "distraught, frightened and a little lost" following her arrest.
"What she said is that there came a time when she felt they were a family, and she loved the girls very much, and she loved Jaycee very much," he said.
According to Ms Dugard's stepfather, the girls have grown up believing that she was their elder sister, and that Nancy Garrido - who married convicted rapist Phillip Garrido in 1981 while he was in jail - was their mother.
Ms Dugard, now 29, had allegedly been kept as a prisoner for 18 years in a secret compound of tents and sheds behind the Garrido home in Antioch, east of San Francisco.
Her identity was only discovered last week, after Garrido was ordered to a parole meeting by police officers.
He had been noticed acting suspiciously with the two girls as he tried to enter the University of California, Berkeley, campus to hand out religious literature.
Also on Wednesday, police in neighbouring Pittsburg said that no evidence linking Phillip Garrido to the murders of several prostitutes in the 1990s had been discovered at the property.
"Aside from a few items that will require further forensic examination before they can be completely excluded, we did not locate any evidence to connect the Garridos to Pittsburg's unsolved cases," Lt Brian Addington said in a statement.
Police discovered an unidentified bone fragment at a property next door to the Garridos' Antioch home over the weekend, but they said it was too early to determine whether it was human or animal.
US media reports have said Ms Dugard bonded with 58-year-old Garrido and had helped to run his printing firm.
