Several neighbours -- some whose homes were burglarized by Col. Russell Williams -- want the sex killer's cottage in Tweed, Ont., knocked to the ground just as Paul Bernardo's house of horrors was in Port Dalhousie, Ont.

The cottage is where Jessica Lloyd, 27, spent her last moments alive being raped and tortured by Williams.

The man who once flew the Governor General broke into Lloyd's Belleville, Ont., home in January, sexually attacking her before abducting her to his cottage where he kept her for a day as his sex slave before murdering her.

His next-door neighbour on eastern Ontario's Cosy Cove Lane, Monique Murdoch, is among those who think the cottage that Williams and his wife bought in 2004 should be razed.

The former commander of Canadian Forces Base Trenton broke into Murdoch's home three times. The first time was in September 2007 in what was the first of the colonel's 82 fetish break-and-enters.

Murdoch, who had been friends with Williams and his wife, said it's hard to look at the house after knowing what happened there.

"Until yesterday, we didn't think anything had happened in the house," Murdoch said from her home on Wednesday.

"But now that something has, the house is tainted, it's bad...I don't think anybody can go and live in that house now."

Ernestine Cole, who said she lives four doors away from Williams' cottage, also doubts that anyone would buy the home, given his heinous crimes.

"It might be a good idea just to tear it down. There might be some evidence in there," said Cole.

She said she was distressed to hear about the details of Williams crimes.

"With all the new information we're getting, it was bad enough to know that he had done these things, but how he did them. This is what's shocking too," she said.

The cottage where Lloyd was murdered sits empty. The back lot has gone to weeds. Neighbour Larry Jones, who police initially considered a suspect in the sexual assaults, has been mowing the front lawn, according to another neighbour, Jason Gulliver.

Williams broke into Gulliver's home twice in 2007 and 2008 and stole items to feed his lingerie fetish.

Gulliver, who is part of the neighbourhood association, would like to see the cottage torn down, "especially once all of the information came out that poor Jessica was brought up there... it's even worse now."

It could be costly, and he doesn't know what the process would be to accomplish that.

"If that thing was levelled down, we would do a couple of charity events and then do a tree-planting or something," said Gulliver.

"Whether it was donated to some of the victims or just a plain and simple tree planting, whatever, but there's certainly a better use for the spot."

It's not clear whether a $2.45-million lawsuit field against Williams and his wife, Mary-Elizabeth Harriman, by one of Williams' sex assault victims would affect any plans to demolish the structure, owned solely by Williams.

Demolishing the notorious homes of serial killers has been done before.

John Wayne Gacy's house in suburban Chicago was destroyed by police as they uncovered 27 of his 33 victims, who'd been killed from 1972-1978, buried under his home.

All the buildings have been removed from Robert Pickton's pig farm in Port Coquitlam, B.C., where he killed and dismembered his victims. Pickton was convicted of killing six women while charges in the deaths of 20 more were stayed.

The rented two-storey pink clapboard house where Bernardo and his wife Karla Homolka raped, tortured and killed Ontario schoolgirls Leslie Mahaffy and Kristen French was bulldozed in December 1995.

Debbie Mahaffy, whose 14-year-old daughter was killed by the couple, was among those who watched the home at 57 Bayview Dr. reduced to rubble.

The Ontario government bought the Cape Cod-style house for $95,000. The house, a grim reminder of the couple's crimes, was reduced to a pile of wood fragments, shingles and broken concrete and hauled to an undisclosed site to be buried. Another house was later built on the site.

A spokesman for Ontario's Ministry of the Attorney General said it's too early to say whether the government would consider purchasing the home.

"It would be premature to speculate on anything related to this property -- this case remains before the court," Brendan Crawley said in an email.
