Every April 5 for the past 10 years, Phillip Garrido registered on his birthday with the Contra Costa Sheriff’s Office as a convicted sex offender. Two to three times a month, he met his parole officer at the parole office or his Antioch, Calif., home. Since at least January, the state monitored him with a global positioning device strapped to his ankle.
Yet police say he managed to conceal Jaycee Lee Dugard, whom he is accused of kidnapping and sexually abusing, in a squalid backyard encampment for 18 years. The charges are causing authorities to rethink their procedures as they question how a registered sex offender could lead a secret life while under their supervision.
