ANTIOCH — His neighbors knew he was a registered sex offender. Kids on his block called him "Creepy Phil" and kept their distance. Parole agents and local law enforcement regularly visited his home and found nothing unusual, even after a neighbor complained children were living in a complex of tents in his back yard.
For 18 years, Phillip Garrido managed to elude detection as he pulled off what authorities are calling an unfathomable crime, kidnapping and raping 11-year-old Jaycee Lee Dugard, keeping her as his secret captive for nearly two decades and fathering her two children.
The question about how he went unnoticed became more pressing Friday when Garrido came under suspicion in the unsolved murders of several prostitutes in the 1990s, raising the prospect he was a serial killer as well. Several of the women's bodies — the exact number is not known — were dumped near an industrial park where Garrido worked during the 1990s.
Authorities acknowledged that they blew a chance three years ago to rescue Dugard from the backyard labyrinth of sheds, tents and outbuildings that were concealed from the outside world.
Never miss a local story.
A neighbor called 911 in November 2006 and described Garrido as a psychotic sex addict who was living with children and had people staying in tents in his back yard.
The investigating officer spent a half-hour interviewing Garrido on his front porch but did not enter the house or search the back yard, Contra Costa County Sheriff Warren E. Rupf said. The deputy, who did not know Garrido was a registered sex offender even though the sheriff's department had the information, warned Garrido that the tents could be a code violation before leaving.
"We missed an opportunity to bring earlier closure to this situation," Rupf acknowledged. "I cannot change the course of events but we are beating ourselves up over this and continue to do so."
It was not the only missed opportunity.
As a parolee, Garrido wore a GPS-linked ankle bracelet that tracked his every movement, met with his parole agent several times each month and was subject to routine surprise home visits and random drug and alcohol tests, California Department of Corrections and Rehabilitation spokesman Gordon Hinkle said.
The last unannounced visit by a team of local police agencies was conducted in July 2008. Paramedics also were summoned to the house five times since 1999, presumably to help Garrido's 88-year-old mother, who had dementia.
"There was never any indication to my knowledge that there was any sign of children living there," Hinkle said.
As it turns out, Dugard and her two children were living there as prisoners, authorities say. The heavily wooded compound was arranged so that people could not see in, and one of the buildings was soundproofed and could only be opened from the outside.
Neighbors knew there were children living there. Damon Robinson has lived next door to the Garridos for more than three years and his then-girlfriend in 2006 told him she saw tents in the back yard and children. "I told her to call police. I told her to call right away," he said.
Dugard, now 29, was reunited with her family and said to be in good health, but feeling guilty about developing a bond with Garrido over the years. Her two children, 11 and 15, remained with her.
"Jaycee has strong feelings with this guy. She really feels it's almost like a marriage," said Dugard's stepfather Carl Probyn.
Probyn has been in constant contact with Dugard's mother, his ex-wife Terry Probyn, since she found out Wednesday that her daughter was alive.
Probyn said both mother and daughter are trying to avoid the public eye for now. After not seeing each other for 18 years, Dugard greeted her mother by saying, "Hi, mom, I have babies," according to Probyn. Dugard had her two daughters with her at the reunion, and it appears she never told them she was kidnapped by their father, he said.
She is now free thanks in large part to two quick-thinking police employees at the University of California at Berkeley who came across a rambling Garrido this week, with Dugard's two daughters in tow. He was on campus because he wanted to hold some sort of religious event.
Garrido seemed incoherent and mentally unstable, and the girls wore drab-colored dresses, were unusually subdued, had an unnaturally pale complexion and appeared robotic and rehearsed when they spoke, said Lisa Campbell. They said they were home-schooled by their mother and had a 29-year-old sister at home.
Colleague Ally Jacobs ran a background check on Garrido and notified his probation officer. On Wednesday, Garrido arrived at the probation officer's building with his wife, the two girls and a woman who initially identified herself as Allissa. She turned out to be Dugard and investigators said Garrido confessed to the kidnapping.
Garrido and his wife pleaded not guilty Friday to a total of 29 counts, including forcible abduction, rape and false imprisonment.
Phillip Garrido appeared stoic and unresponsive during the brief arraignment hearing. His wife cried and put her head in her hands several times.
Garrido was required to register as a sex offender because he was convicted in 1977 of kidnapping a 25-year-old woman from parking lot in South Lake Tahoe, the same town Jaycee Dugard lived in when she was snatched from a bus stop.
He was convicted of raping the woman multiple times at a Reno storage unit that the investigator from the case described as a "sex palace." It featured various sex aids, sex magazines and videos, stage lights, wine, and a bed, said investigator Dan DeMaranville.
Gail Powell, spokeswoman for the Nevada Department of Public Safety, said Garrido met his wife while he was serving time for the rape at the federal penitentiary in Leavenworth, Kan.
He served about 10 years of a 50-year federal sentence for kidnapping, and less than a year for a concurrent Nevada sentence of five years to life in prison for sexual assault. He was paroled in 1988, said Nevada Department of Corrections spokeswoman Suzanne Pardee.
A violation of Garrido's parole conditions sent him back to federal prison from April to August of 1993. Dick Carelli, spokesman for the federal Office of Court Administration, did not know what Garrido did to violate parole. Authorities are trying to piece together how and by whom Dugard was held during Garrido's four-month absence.
