A northeastern New Brunswick mother thinks someone in a nearby community knows where her 16-year-old daughter is and she is confronting people for clues.

Pam Fillier, whose daughter Hilary Bonnell disappeared from Eskinuopitijk First Nation, commonly known as Burnt Church, on Sept. 5, said she plans to continue to pressure people until she finds her daughter.

One area that Fillier has targeted in her search for her daughter is the nearby community of Rivière-du-Portage.

Fillier said the people she believes are responsible for abducting her daughter have threatened her and told her to back off.

"To the people that have my daughter. I'm not a woman who will run home and cry. I'm not leaving," Fillier said on Tuesday.

"Like I said that night, give me what I want and I'll go away. Give me my daughter. I'll go away. Other than that, I'm here to stay. I'm not leaving until I get my daughter back and that is a promise."

Although Bonnell's family has not given up searching locally for the missing teenager, they are now raising money for a national billboard campaign to develop leads.

They're hoping that billboards set up outside the community will help widen that search.

The RCMP are continuing to investigate Bonnell's disappearance.

Bonnell has dark eyes and black, shoulder-length hair. She is five feet five inches tall and weighs about 134 pounds. She was last seen wearing a purple T-shirt, a black sweater, jean shorts and sandals.
