On Thursday, Col. Russell Williams was charged with 82 more offences, including 46 counts related to break-ins in Tweed. (Department of National Defence/Canadian Press)A sexual assault victim from Tweed, Ont., said she felt "totally betrayed" by police when she learned Col. Russell Williams had been charged with dozens of other crimes dating back to 2007.

"I'm just sick about it," the woman told CBC News on Thursday. "They kept telling me this [assault] was a one-time occurrence — this was just a sex pervert that wanted pictures and it's their experience that this person would never return."

The woman was sexually assaulted and photographed during a home invasion on Sept. 30, 2009. In February, 47-year-old Williams, then commander of Canadian Forces Base Trenton, was charged in that attack, along with an earlier home invasion and sexual assault.

He was also charged with first-degree murder in the deaths of Jessica Lloyd, 27, and Cpl. Marie-France Comeau, 37.

On Thursday, he was charged with 82 more offences, including 46 counts related to break-ins around Tweed, where Williams had a cottage. The other counts related to similar incidents in Ottawa's Fallingbrook neighbourhood, where Williams lived until recently.

The victim of the Sept. 30 attack now believes her assailant may have visited her house a year earlier, when an article of her clothing went missing.

"They were trying to solve this investigation without scaring people," she said. "They weren't getting it [the information] out. This was a serious thing … I feel that they've let a lot of people down. I feel a lot of things could have been prevented."

She isn't the only Tweed resident shocked by the latest charges and left questioning why police were so quiet about the crimes taking place.

Roseann Trudeau, advertising and circulation manager of the Tweed News, said she had no idea until Thursday that there had been so many break-ins in the community.

"This accused killer was [allegedly] in these homes — all these homes! That's just unbelievable," she said, adding that she doesn't know how police failed to connect the cases.

Trudeau said little attention was paid after the first sex assault that Williams was later charged with. Police did issue a warning after the second assault and reported some break-ins, but only on an individual basis.

"How come the public wasn't alerted of someone like this in the area so that we could be on the lookout?" she asked. "And then just maybe Jessica [Lloyd] would be alive today."
