A tent is set up the far backyard of a home in Antioch, Calif., Friday, Aug. 28, 2009,

where authorities say kidnapped victim Jaycee Lee Dugard lived. The twisted kidnapping case of a woman held captive for 18 years in a secluded backyard compound took another disturbing turn Friday as authorities searched the home of her alleged captor for evidence in the murders of several prostitutes and new evidence surfaced of missed opportunities to arrest him years ago.
