Why Was Garrido Released on Parole?

Garrido, a convicted sex offender, and his wife Nancy Garrido were arrested Wednesday Aug. 26, 2009 for the 1991 kidnapping of an 11-year-old girl who recently walked into a Northern California police station, authorities said Thursday, Aug. 27.

Fifteen years before he allegedly kidnapped Jaycee Dugard in 1991, Phillip Garrido was sentenced to a 50 years to life sentence for kidnapping and raping Katie Callaway.

Today Callaway still can't believe he was out of jail.

"Not human. That would be the word," Callaway said. "I don't think he knows reality. I don't think he knows right from wrong. And if he does, he doesn't care."

The fact that Garrido was paroled 11 years into his sentence and is accused of kidnapping and raping again has raised serious questions about the parole process and just how much supervision actually takes place, reports CBS News correspondent Hattie Kauffman.

"They may not have violated their own rules, but I think it's pretty clear they violated what would be considered good parole practice," said Jonathan Simon, a law professor with the University of California Law School at Berkeley.

Simon says parole rules were very different back in the 70s when Garrido was sentenced. There was a lot of wiggle room for early release. Guidelines became stricter in the '80s.

About 1 in 8 of the nation's parolees are in California. That's 111,000 former inmates, and each parole officer has an average of 70 cases; sometimes, complacency can set in.

"They just didn't view Mr. Garrido as that serious a threat, because he had been on parole a long time," Simon said. "He was living with his wife, he was fully employed."

Tuesday at the house where Jaycee and her daughters were kept prisoners there is a pause in police activity, after detectives announced late yesterday they had discovered a bone fragment on the neighbor's yard, where Garrido once lived in a shed. No word yet whether that bone is animal or human.
