ABC News' Linsey Davis reports:
Amanda Berry is now free after allegedly being held captive only a short drive from where she disappeared a decade ago in Cleveland, and similar cases provide a glimpse of what she might be experiencing.
"The mind manipulation plus the physical abuse I suffered in the beginning, there was no leaving," said Jaycee Dugard, who was kidnapped in 1991 when she was 11 and held captive for 18 years by Phillip and Nancy Garrido in Antioch, Calif.
Dugard told ABC News' Diane Sawyer in her only television interview ever that even when the doors were unlocked, she never tried to run.
"Something always held me back," Dugard said last year. "It was like I had still had those handcuffs on."
Unanswered this morning is how Berry, now 27, and two other women, as alleged, were held against their will for so long so close to their friends and families.

Georgina DeJesus, 23, Michele Knight, 32, and Berry had even apparently seen themselves on TV and heard their families' pleas.
"I'm Amanda Berry. I've been on the news for the last 10 years," she pleaded Monday night with the operator on her frantic 911 call.

As they recover and adjust to their new-found freedom, Berry, DeJesus and Knight are not alone.
Elizabeth Smart was 14 when she disappeared in 2002 in Salt Lake City, Utah, and was found nine months later 18 miles away from home. She says she was simply too afraid to speak up or try to escape.
"It feels just like you're losing control of everything. You just feel like the world is coming to an end," Smart, now an ABC News contributor, said in 2011.
The next few hours or days will most likely reveal what kept the alleged captives in the Seymour Avenue house in Cleveland. The police chief says he believes the women were tied up.
Charles Ramsey, the man who helped Berry escape, described the scene Monday as a woman "going nuts to get out of a house."
