Abusive persons, deviants have a strong 'pattern of abuse' which has to be followed up, to prevent gross damage to society. These serial killers have other criminal activities to fund their lusts - like stealing money from elderly strangers (nest egg), and care-taking other's property.
It is the duty of 'Govenmental law enforcement agencies' to monitor registered sexual offenders.
Police fear Jaycee Lee Dugard kidnapper is linked to murders of 10 prostitutes and a girl of 15
31st August 2009
Detectives began digging up the gardens of kidnapper Phillip Garrido and his next-door neighbour yesterday amid fears that they are dealing with a serial killer..
Possible links are being examined between up to ten murdered prostitutes and the monster who kept Jaycee Lee Dugard in a back-garden prison for 18 years.
Police believe Garrido might also have killed 15-year-old schoolgirl Lisa Norrell, whose body was discovered in 1998 dumped in a remote industrial area close to where he used to work.
A spokesman would say only: 'Unfortunately, there is a larger story to it that we can't go into right now.'
Her stepfather Carl Probyn, 60, said Jaycee, who was 11 when she was snatched from the street, was 'fragile' but was 'a great mother'.
Her daughters, named Starlet and Angel, were photographed at a birthday party only days before their shocking story was discovered.
The picture was taken on August 15 by Cheyvonne Molino, a client of Garrido's printing business, at a party she threw for her daughter's 16th birthday.
Mrs Molino said Garrido asked if the girls could go to the party and left them unattended there.
The girls did not appear anxious or desperate to get away from Garrido. Mrs Molino described the younger girl as very talkative and always asking questions, with her older sister more reserved.
'He left the girls with us at the party. It wasn't like he was standing guard over them.
'The 11-year-old was everywhere, asking lots of questions. The 15-year-old was a little more passive.
'At the party a girlfriend of mine pointed out to me how clingy the older girl was to Phillip. It was almost like she was sending out a message, "That's my man". At least that's how it looked to us.
'The young girl did say a couple of things that seemed a little strange at the time. She told me her daddy had a church in the basement of their house.'
At Garrido's home in Antioch, northern California, police with shovels, rakes, hoes and even chainsaws were searching for clues.
Until three years ago, Garrido, 58, acted as caretaker of the house next door to his property, which also has a number of sheds and outbuildings which have now been cordoned off by
Damon Robinson, who now lives in the house, said all the locks were turned around so people could be locked in, rather than locked out.
'It took me a while to realise, but Garrido had access to all of these buildings. At first I didn't even realise they were part of my land because there are wire fences splitting up the yard.
'When I moved over in one of the sheds there was a music player, a couch, a mattress and a VCR. He really wanted the VCR back when I found it.
'There had been times when I could hear music coming from there at night. Maybe he was taking the girl over there for a change of scenery or something a little nicer than he had in his yard, I don't know.'
Lisa Norrell's mother, Minnie, said she was visited by a murder squad officer on Saturday and he told her police were looking at the possibility that Garrido was involved in her daughter's death in November, 1998.
'I'm really excited about that. It's the first glimmer of hope we have had since my daughter passed away. I'm hopeful that's who it is, just so there is an end. There will never be closure, but there will be an end.'
The schoolgirl's body was found in an industrial park in Pittsburg, California, close to where Garrido used to work and close to where the bodies of several prostitutes were also found more than a decade ago.
Valerie Schultz, 27, Rachael Cruise, 32, and Jessica Frederick, 24 - were found beaten, strangled or stabbed to death in the same area in 1998 and 1999 and thrown into a ditch. Seven other known prostitutes were also killed in the area in the early 1990s.
Contra Costa County police spokesman Jimmy Lee last night confirmed the expanded search is tied to investigations of unsolved cases in the area. He refused to give any further details, saying the investigations are 'preliminary'.
Garrido has been quizzed over the killings, but said nothing to indicate he was responsible.
One theory is that Garrido abducted the women, took them back to his compound and raped and killed them before dumping their bodies.
Photographs of his sinister lair emerged yesterday, showing the appalling conditions Jaycee was forced to live in for 18 years.
Incongruously, a handpainted Welcome sign was nailed to a tree, leading to a filthy compound of ragged tents and ramshackle sheds.
A former neighbour, Patrick McQuaid, said he spoke to Jaycee through the fence soon after she was abducted in 1991, but did not realise she was a missing girl.
Mr McQuaid, 27, was a child when he saw the pretty blonde girl through the chicken wire that then separated their homes.
She told her she was living at the house and that her name was Jaycee, but before she could say any more she was ushered back into the house by Garrido.
'I didn't think anything of it - I was young,' he said, adding that a tall fence was put up days later.
WERE TWO MORE GIRLS HELD CAPTIVE?
Two girls aged about four were spotted at the house where Jaycee Lee Dugard and her two daughters were held captive, it was revealed yesterday.
Police were warned two years ago that the children were living with convicted rapist Phillip Garrido.
But according to a neighbour, officers failed to follow up the call because they said they did not have a search warrant.
Now detectives in Antioch, northern California, are desperately trying to discover if any more children were living with the Garridos apart from Jaycee, now 29, and her two daughters, aged 15 and 11.
Erika Pratt, who was living next door to the Garridos two years ago, claimed: 'He had little girls and women living in that backyard and they all looked kind of the same. They never talked and they kept themselves to themselves.'
Miss Pratt, 25, said the core group consisted of two girls aged about four, one about 11, another about 15 and a young woman aged about 25. 'They were all blonde.'
She said she called the Contra Costa County sheriff's department to investigate but officers said they were unable to help.
'They told me they couldn't go inside because they didn't have a warrant. So they just told him they'd keep an eye on him.'
Miss Pratt said she was 'freaked out' by Garrido's behaviour and said she saw his secret compound. As well as the sheds and tents in the garden, she said there were pit bull dogs.
Police said they were investigating 'all possible leads' concerning the case. A spokesman said the only people living in the garden when the Garridos were arrested were Jaycee and her children.
Sheriff Warren Rupf admitted on Friday that police bungled by failing to find Jaycee on two visits to the Garrido house in 2006 and 2008.
HE'S A MONSTER, SAYS FIRST RAPE VICTIM
Phillip Garrido's first known victim broke her public silence yesterday to say: 'He's a monster.'
Kathleen Callaway was a 25-year-old casino worker in 1976 when she agreed to give a lift to Garrido as she travelled home to Reno, Nevada.
High on LSD, he overpowered and handcuffed her before driving to an isolated warehouse which had been kitted out with sex aids, pornographic material and stage lights.
The terrified young woman was stripped naked and raped. Miss Callaway, now 58 and living in Las Vegas, said she was 'shocked' when she learned that the suspect in the Jaycee Lee Dugard case was the same man who attacked her.
Her ordeal came to an end when a policeman on a routine patrol noticed a light on in the storage facility in the early hours of the morning and went inside to investigate. Clifford Conrad found Garrido shirtless and wearing jeans. 'I asked him what he was doing in there', said officer Conrad, who is now retired.
Before Garrido could answer, a female voice cried out from inside the warehouse, and a woman emerged from behind a curtain naked. She told the officer she had been kidnapped and raped. 'Garrido didn't seem nervous or anything,' said the officer. 'He just said they were boyfriend and girlfriend, and they were just having consensual sex.'
Garrido was taken to the police station where he was questioned by Detective Dan De Maranville. The detective recalled: 'I said, "What the hell are you resorting to this for?"
'He said that's the only way he gets sexual gratification. The guy should have been castrated while he was in prison.'
Garrido, who was 25 at the time of the attack, was given a 50-year sentence for kidnap and rape but served only 11 years. Three years after his release he snatched Jaycee, then aged 11, from a bus stop.
Mr Conrad, now 66, said he was outraged that Garrido was free to kidnap Jaycee Dugard. 'Someone dropped the ball,' he said. 'How he got out I'll never know. I guess a lot of people dropped the ball his whole life.'
MORE HORROR STORIES
Garrido's bookshelf, pictured above, features a bizarre collection of tatty novels ranging from horror and fantasy to Danielle Steel romances.
However, one author dominates the hundred or so paperbacks - American horror writer Dean Koontz.
His book Intensity, seen in the centre of the middle shelf, features a delusional character who turns into a serial killer and rapist, at one stage keeping a young girl in the cellar.
Garrido is also a fan of the Psychosphere trilogy by British writer Brian Lumley. The books revolve around a world in which people use their mental powers to control others. Garrido calls himself 'the man who spoke with his mind' and believes he has telepathic abilities.
Also in the collection are a handful of children's favourites including The Chronicles of Narnia by CS Lewis.
Four Danielle Steel romances, more likely to have been read by his wife Nancy, include To Love Again and Star.
