One week after eight-year-old Victoria Stafford disappeared in the southwestern Ontario city of Woodstock, her mother urged police to treat her disappearance as an abduction.

"Well this is an abduction — this is a missing child," Tara McDonald said Wednesday. "Somebody has abducted her, it's obvious. They took my child. So, I mean, I wish it would be treated as an abduction, because it is."

Police say they are still chasing leads and have not identified the woman who led the girl away on April 8.

Const. Laurie-Anne Maitland, spokeswoman for the Oxford Community Police, has said the 30 investigators on the case have been working around the clock to find the missing child.

The only tangible lead police have publicly discussed is a surveillance video showing a woman with long black hair and a puffy white coat with Tori, as the girl is known to family and friends.

Though the police have received more than 500 tips, no one has yet been able to name the mystery woman.

"We are still looking for the identification positively of the female person in the surveillance video," Maitland said.

"We still have officers canvassing in the area. They continue to do that. They continue to search properties, search business compounds … in the hopes of collecting some type of evidence that will hopefully lead us to finding Tori," she said.

"I have no extra information in the last few days to share."

Family members said they have been endlessly watching the video and racking their brains. Tori's father, Rodney Stafford, estimates he has watched the tape more than 400 times.

"From the first time that I watched that video, there has always been something about that stride, but I just can't place it," he said. "I can't at all."

Stafford, his sisters and his mother, McDonald, her boyfriend and his mother were among those who attended a car wash and barbecue fundraiser on Wednesday.

Organizers said the money raised will go into a trust for Tori and her brother, Daryn, 10, intended to pay for the counselling their family says they will both need when Tori returns.

Also on Monday, police called off the massive ground search for Tori, saying it appeared she left her school "willingly" with the woman and no evidence has been found to suggest foul play.

The woman's face is not clear in the enhanced video. She is described by police as between 19 and 25 years old, between 120 and 125 pounds, with long, straight black hair in a ponytail.

She was wearing a baggy white coat and black jeans.

Maitland told an afternoon news conference in Woodstock on Wednesday that police continue to receive tips and cautioned people not to believe everything they hear.

"If you read it on Facebook, it doesn't mean it's true," she said.

Stafford's parents separated last December. Stafford, who described the relationship as "an ongoing struggle," has said he doesn't believe any of Victoria's relatives are behind her disappearance.
