Phillip Garrido, the man accused of kidnapping Jaycee Dugard and holding her prisoner for 18 years, walked into the FBI field office in San Francisco two days before his arrest and handed over a letter describing how he'd cured his disturbing sexual behaviors and how the information could be used to assist in curing sexual predators.
The FBI spokesman in San Francisco told ABC News the rambling letter is very similar to the postings on Garrido's website.
The document that talks about cures for sexual predators and ways of "controlling human impulses that drive humans to commit dysfunctional acts."
Police in Contra Costa County, Calif., expanded their investigation into the 1991 kidnapping of Dugard this weekend.
Officials searched an Antioch, Calif., property next door to the home of Phillip and Nancy Garrido who have been charged in the 1991 kidnap and rape of Dugard.
Dugard was found last week and reunited with her family 18 years after she was snatched from outside her South Lake Tahoe home.
Police are reportedly calling the adjacent property part of a crime scene, but details were not released, according to ABC affiliate KXTV in Sacramento.
The Associated Press reports that years ago, Phillip Garrido served as a caretaker for the property.
"It's been 18 years," Carl Probyn told "Good Morning America," Sunday. "I'm glad we got her back, I don't care about him."
Probyn, 56, a wallpaper hanger, was suspected by some in-laws of being involved in the 1991 abduction. He concedes finding Dugard, who is now 29, is also a relief for him personally. "I'm free now," he said. "They caught him and it's solved."
Probyn says he's unaware if any of his relatives will apologize, but says he told his estranged wife Terry Probyn this weekend, "I don't want these people back in my life -- they actually raised money to hire detectives to put me in jail."
But he told "GMA" he would love to see the family reunited like it was before Dugard's disappearance. "This has been 18 years of hell," he said.
On the Antioch street where Phillip Garrido lived, the neighborhood kids nicknamed him "Creepy Phil." Now that he and his wife face 29 felony counts for what he allegedly did to Dugard over the past 18 years, Garrido, if convicted, will almost certainly die in prison.
During most of Garrido's 58 years, criminal records show a pattern of abusing or manipulating women.
His father, Manuel Garrido, is the first to admit his son was a troubled teenager.
"He was on LSD and he had a serious motorcycle wreck and hit his head," Manuel Garrido told reporters.
Phillip Garrido was first caught 33 years ago. A patrol officer saw a curious light inside an 8 foot by 10 foot storage unit in Reno, Nev. A police detective repeatedly banged on the door.
"He kept banging on the door until Mr. Garrido opened the door ... and a naked woman ran out," explained Dan DeMaranville, of the Reno police department. The officer then "stuck a gun up the guy's nose and that was end of that party," DeMaranville said.
Police say Garrido's storage unit looked like a scene from a porno film. Garrido confessed to rape and was sent to Leavenworth Prison in Kansas.
Even from inside the penitentiary, DeMaranville said, Garrido convinced a woman, Nancy Boconegra to marry him. She has stayed with him to this day.
"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.
