WOODSTOCK, Ont. - The mother of Victoria Stafford said Monday an anonymous donor has offered to put up however much money is needed to bring the missing eight-year-old girl home.

"The police are in the process of looking into it, but I feel in my heart that it was a genuine offer," Tara McDonald said at her daily news conference outside her home.

"I don't think that it's just a person who's trying to get into the media or get their two cents in. I really feel that it's a genuine offer."

McDonald and police both stressed that the girl's abductor has not contacted family members or investigators asking for a ransom.

The girl, known as Tori to family and friends, hasn't been seen since she left her school on April 8.

Police have released a composite sketch based on a video of a woman seen walking with Tori the day she went missing, but have disclosed no other major leads in the case.

McDonald also admitted Monday she broke down after police gave her a polygraph test three days after her daughter was taken.

"I ended up breaking, and I ended up leaving, so it's not because they didn't give me the results of my polygraph test, and it's not because I had anything to hide," McDonald said after being pressed by a reporter on her test results.

"It's because it had been three days since my daughter was missing. I hadn't slept, I was ready to snap, and I said, `I just want to go. I want to get out of here and I want to go home."'

Although she said she completed the test, McDonald said she would be willing to take another one now that she's calmer.
