1 of 2 The 18-year mystery about what happened to Jaycee Lee Dugard, last seen being grabbed as she walked to her bus stop, ended with a routine parole check.
On Tuesday, Phillip Garrido, 58, was reported to parole authorities after he was seen with two small children at the University of California at Berkeley, said Scott Kernan, undersecretary for the California Department of Corrections and Rehabilitation.
The next day, a parole agent ordered Garrido to appear for questioning and he did so, accompanied by two children and a woman, Kernan told reporters.
During questioning, he admitted to having abducted Dugard in South Lake Tahoe, and said the two children were his, Kernan said.
He and and his wife, Nancy, were taken into custody and held at the Concord, California, jail. An officer at the jail said the two had been booked and were ordered held on $1 million bail, but were no longer there.
Phillip Garrido had been booked on charges of kidnapping, conspiracy and related offenses, the officer said. Nancy Garrido was booked on charges of kidnapping and conspiracy.
Phillip Garrido was paroled from a Nevada state prison June 8, 1988, and served time in federal custody and in Nevada for sexual assault, the corrections department said. The Department of Justice's Megan's Law page shows that the arrest involved a charge of forcible rape.
Dugard, now 29, is in "good health," the El Dorado County Sheriff's Department said.
Earlier Thursday, Carl Probyn, Dugard's stepfather, said an FBI agent had called his wife, Terry, on Wednesday afternoon to tell her that Dugard had been found.

At the time, "it was reported that a vehicle occupied by two individuals drove up to Jaycee Dugard and abducted her in view of her stepfather," the El Dorado County Sheriff's office said Thursday.
The El Dorado County Sheriff's office scheduled a news conference for 3 p.m. (6 p.m. ET) to discuss the case.
Probyn said his wife, who was flying Thursday from Southern California to meet with Dugard, spoke to her daughter on Wednesday.
"Jaycee remembers everything," he said. "They talked back and forth and she had the right answers to all my wife's questions."
He said, "I'm feeling great! ... It's like winning the Lotto."
Ernie Allen, president of the National Center for Missing and Exploited Children, said the reappearance of Dugard is "absolutely huge."
"One of the things that we preach to searching families all the time ... is that even in these long-term cases there's hope," he said.
"Even in these long-term cases ... it's important that we not let the world forget."
