Girl Grew Up Locked in Backyard Shed

(CNN) -- From the time she was an 11-year-old, blue-eyed, freckle-faced blonde until she was a 29-year-old woman with two children, Jaycee Dugard was kept locked away in a backyard compound of sheds and tarps by a couple police say abducted her.

She was more than 160 miles from home, and her family had no idea where she was.

Nobody else knew she was there except the couple that snatched her off the street in front of her house in South Lake Tahoe, California, in 1991, and took her straight to the soundproof shed, police said.

Dugard's pocket of Phillip and Nancy Garrido's backyard in Antioch, California, was so overgrown no one even knew it existed.

The details about Dugard's time in captivity emerged Thursday after one of Northern California's most enduring mysteries was solved and the Garridos were arrested and accused of her kidnapping.

Anyone who came across the couple's backyard, littered with garbage cans and a dishwasher, would assume that it ended at a six-foot fence.

"You could walk through the backyard and never know there was another set of living circumstances," said Fred Kollar, undersheriff of El Dorado County. "There was nothing that would cause you to question it. You can't see it from either adjoining property. It was presumably well arranged."

But tucked away beyond the tangle of bushes, high grass and trees was a blue tarp that concealed the only world Dugard had known since her abduction.

In it were sheds and tarps, a makeshift bathroom and shower, along with electricity supplied by an extension cord. Kollar compared the primitive conditions to camping.

Dugard lived for several years there by herself. The sheds were locked from the outside.

She grew up and had her captor's children there, and raised them there.

"None of them have ever been to school, they've never been to a doctor," Kollar said. "They were kept in complete isolation in this compound, if you will, at the rear of the house," he said. "They were born there."

The children, both girls, are now 15 and 11.

"They are all in good health," Kollar said in response to a question about how Dugard and her children are doing. "But living in a backyard for the last 18 years does take its toll."
