"He's a pervert," DeMaranville said. "He should have been neutered while he was in prison."
But Garrido was paroled after only 10 years of a 50-year sentence.
After his release, police say Garrido and his wife, abducted 11-year-old Dugard in 1991 from a street outside her South Lake Tahoe, Calif., home, and imprisoned her in a shed behind their home in Antioch.
Neighbors are outraged at the police and a parole system that missed numerous opportunities to rescue the kidnapped young woman.
Probyn said on "GMA" Sunday he understands the team of doctors and psychologists helping Jaycee Dugard know it will take years to get her through the ordeal.
Police say she bore two children fathered by Garrido while she was held captive.
"This is a one-of-a-kind deal -- this has never happened before," Probyn said.
