His own dad thinks he’s not only a sexually perverted monster, but a murderer, too.
Manuel Garrido, 87, sullenly acknowledged yesterday that he believes his son Phillip — charged in the horrifying child abduction and rape of Jaycee Dugard — is also the killer in a slew of unsolved cases involving prostitutes and other young women.

“He was a sex addict — that was his problem,” Manuel Garrido told The Post. “I believe my son killed the prostitutes.”
Meanwhile, authorities combing through the Antioch, Calif., house and property where Garrido and his wife, Nancy, lived — keeping a secret hell-hole compound of shacks and sheds to conceal Jaycee and the two daughters fathered by Phillip Garrido — started to board up the home yesterday afternoon.
Officials fear that disgusted neighbors will try to burn the place down, sources said.
The Garridos have been charged in the abduction and rape case involving Dugard, who was kidnapped at age 11 from a bus stop near her South Lake Tahoe home and turned into a sex slave for 18 years.
At a property next door to the house of horrors, investigators — bearing rakes, shovels and chainsaws — searched an area where Phillip Garrido briefly lived in a shed while working as a caretaker from 2005 to 2006.
By midday, cadaver-sniffing dogs were also brought to the site. Two bags of evidence were carted away, but it wasn’t clear what was inside or which property they were collected from.
Magdalena Miller, who owns the property next door, said she was “shocked” at the developments at the home she bought from her ex-husband, Delbert “Jack” Medeiros.
Medeiros was forced by a medical condition to enter a nursing home in 2005, and Garrido moved in to act as a caretaker, she said.
“I talked to him on the phone a couple of times,” Miller said of Garrido, adding she had no idea he was a registered sex offender. “He said his kids were helping him clean the house.”
Jimmy Lee, a spokesman for the Contra Costa County Sheriff’s Department, said of the neighboring property, “We do consider it a crime scene.”
Ka-2 Police in Pittsburg, a Bay Area city near where the Garridos lived, have said they’re now looking into whether Garrido may be linked to several unsolved murders of prostitutes in the region in the early 1990s.
Antioch police are also re-examining unsolved cases, but declined further details.
As The Post reported, Garrido is under investigation for the murder of 15-year-old Lisa Norrell, found strangled in November 1998. Her body was discovered nine days after she disappeared on her way home from a party in Antioch.
Police have also reportedly questioned Garrido about the deaths of three other Antioch-area women in late 1998.
Jessica Frederick, 24, was found on Dec. 5. She died of multiple stab wounds.
Rachael Cruise, 32, was found on Dec. 15. She died of asphyxia and strangulation.
Valerie Dawn Schultz, 27, who was found on Jan. 8, 1999, died of multiple stab wounds. Evidence showed she also had been strangled.
All three were prostitutes.
Garrido’s father is disgusted with his own ex-wife, who he said could have done something to stop the madness.
He said the ex, Patricia, 88, who has suffered from dementia for the last six years, “must have known about Jaycee. She lived there all this time. She could have done something, but didn’t.”
The elderly woman was moved by authorities to an undisclosed nursing home last week, he said.
Last night, Phillip and Nancy Garrido remained in jail after pleading not guilty on Friday to 29 counts, including forcible abduction, rape and false imprisonment.
In Riverside, Calif., where Jaycee’s mom, Terry, lives, neighbors were anxious to help Jaycee and her two daughters adjust to their new reality.
Pink ribbons were wrapped around the trees along Orange Vista Way, and neighbors were busy sprucing up Terry’s home.
“Terry was renovating, but she hadn’t got to the yard yet,” said Anthony De La Torre, a landscaper who lives three doors away.
“The neighbors got together and we’ve been taking shifts. We’re pulling up the weeds, tilling the soil, and now we’re planting flowers. We want the girls to have a nice homecoming. We hope they’ll like it here.”
