An Antioch couple suspected of kidnapping 11-year-old Jaycee Lee Dugard from in front of her South Lake Tahoe home in 1991 and holding her captive for 18 years were charged today with 28 felonies, including kidnapping, rape and false imprisonment.Phillip Craig Garrido, 58, and his wife Nancy Garrido, 55, have been charged with multiple counts of forcible abduction, forcible rape, sexual assault and false imprisonment in connection with Dugard’s disappearance, according to El Dorado County District Attorney Vern Pierson.If convicted of the charges, they could each face multiple life sentences, Pierson said in a prepared statement issued this afternoon.The couple was scheduled to be arraigned between 1 p.m. and 1:30 p.m. today in El Dorado County Superior Court in Placerville. A man and woman believed to be the Phillip and Nancy Garrido snatched Dugard on the morning of June 10, 1991, as she walked from her home to the school bus stop.Her stepfather, Carl Probyn, witnessed the abduction and chased the vehicle, but wasn’t able to catch it.El Dorado County Undersheriff Fred Kollar said at a news conference in Placerville on Thursday that investigators believe the Garridos took Dugard from South Lake Tahoe straight to their home on Walnut Avenue in unincorporated Contra Costa County just outside Antioch, where she allegedly spent the next 18 years living in a complex of hidden sheds in the backyard.While she was being held captive, Dugard had two daughters, now 11 and 15 years old, and investigators have confirmed that Phillip Garrido is their father, Kollar said.Investigators believe that she gave birth to the children at the home and that neither she nor her two children ever went to school or saw a doctor. The three captives lived in complete isolation, Kollar said.Although parole officers had visited the house on Walnut Avenue, they never saw anything to suggest that Dugard or her children lived there, Kollar said.The case began to crack open Tuesday when a police officer at the University of California at Berkeley saw Garrido on campus with the two girls and found their interaction suspicious, Kollar said. He said Garrido was trying to pass out literature on the campus.The police officer checked Garrido’s background and found that he was a registered sex offender on federal parole and called his parole officer.On Wednesday, Garrido’s parole officer had him come to his office in Concord, and Garrido showed up with Nancy Garrido, Dugard, who went by the name “Allissa” and the two girls. Investigators eventually discovered that “Allissa” was actually Dugard.
