BELLEVILLE, Ont. - Family and friends of a Belleville, Ont., woman missing for more than three weeks have put up posters from Kingston to Bancroft in an effort to find her. But police say there's nothing to link the case with other recent crimes in the area.

Deborah Rashotte, 27, hasn't been heard from since Jan. 23. She was reported missing last Thursday.

Katrina Moreau said she was very concerned about her friend, calling it "odd" that Rashotte's cellphone and purse were found in her bedroom at her father's house, where she lived.

"Her cellphone's her life," Moreau said Monday. "She takes it everywhere with her."

Rashotte had been unemployed but was taking a correspondence course, Moreau said. She liked to hang out with her friends and wasn't dating anyone, she added.

"She talks to everybody. She's a happy person."

Moreau said her friend has disappeared in the past but has always kept in touch.

"She would take off everywhere. She would go to Toronto, Hamilton, everywhere, for a week or two. But then she was always in contact with somebody by texting or phoning them and nobody has got in contact with her since the 23rd."

Det.-Insp. Mike Graham of Belleville police said three investigators are working on the case full time, checking places Rashotte might have gone and when she was last seen or heard from.

But he said there's nothing to tie Rashotte's disappearance to the recent slaying of another Belleville woman, Jessica Lloyd. The body of the 27-year-old woman was found near Tweed last week.

Col. Russell Williams, the former commander of nearby CFB Trenton, is charged with first-degree murder in her death.

Graham pointed out that, unlike Lloyd, Rashotte has lived a "nomadic or very transient lifestyle."

"It's not been unusual for her to go missing in the past by her own accord," he said. "She's gone missing for a week or two in the past and she's been located in Hamilton and Toronto and other cities."

Williams has also been charged with first-degree murder in the death of Cpl. Marie-France Comeau, who was found dead in her Brighton home last November, and faces charges in two sexual assaults in Tweed last September.
