No pictures have yet been released of Ms Dugard as she looks today
Police working on the Jaycee Lee Dugard kidnap case have extended their inquiry to the house next door to the property where she was held for 18 years.
Phillip Garrido, who is accused of abducting Ms Dugard aged 11, reportedly took care of the next-door house before the current resident moved in.
He and his wife Nancy deny 29 charges in connection with the case.
Mr Garrido is believed to have fathered Ms Dugard's two children, the first when she was just 14.
She is believed to have been living in tents and sheds in the backyard of the Garridos' Antioch home for 18 years.
Yellow crime scene tape now also surrounds the next-door property, which neighbours say has been the home of Damon Robinson for the past three years.
Mr Robinson had earlier told the Associated Press news agency that Mr Garrido used to act as a caretaker for the property until 2006. Neighbours told AP he used to visit and help out the previous elderly resident.
Jaycee Lee was bundled into a car outside her home in 1991 in South Lake Tahoe, 200 miles (320km) from Antioch.
Her identity was rediscovered last week, after Mr Garrido was ordered to a parole meeting by police officers whose suspicions had been aroused by the behaviour of two girls with him.
The two officers, Lisa Campbell and Ally Jacobs, met Mr Garrido on Tuesday as he sought to hold a religious meeting on the grounds of the University of California at Berkeley, where the officers work.
