More than 50 days have passed since Cedrika Provencher vanished, but her father, Martin, maintains his optimism with the help of emails that arrive daily.

"We get about a hundred emails a day that are filled with words of encouragement,'' Martin Provencher said in an interview.

He says the family continues to receive "lots of information'' on a website set up after the 10-year-old disappeared from Trois-Rivieres, Que., on July 31.

Provencher said the website gets about 10,000 visits daily.

In the latest effort to track down Cedrika, the family is distributing photos of the young girl with different hairstyles.

The computer-generated images show her with a variety of blond, short and streaked hairstyles and wearing glasses.

Quebec provincial police say they have received 1,000 tips since Sept. 6, when they issued a description of a vehicle and a man possibly connected to the girl's disappearance.

They have been looking for a French-speaking man between the ages of 30 and 40 with light brown hair and a medium build.

He was seen driving a four-door red Acura car built between 2002 and 2004.

"We've received tips mainly from the Trois-Rivieres area and across Quebec,'' Lieut. Francois Dore said in an interview.

But there was a hint of frustration in his voice.

"It's kind of worrying because we still don't know, after more than 50 days, where Cedrika is ... that's the problem.''

Last Wednesday, the girl's mother, Karine Fortier, toured French-language media and made an appeal from the heart.

"We're missing maybe just a little piece of the puzzle ... a small piece that will permit us to reach a conclusion to this story,'' she said.

Fortier again urged people who had any information about the kidnapping to contact police.

The 33-year-old woman also called on residents of Trois-Rivieres, which is halfway between Montreal and Quebec City, to keep an eye on friends, neighbours and family members for any change in behaviour.

"It's not stamped on his face, but this man has a daily routine and someone surely has noticed something,'' Fortier said.

Cedrika was last seen helping a man look for a lost dog.

The girl's father recently helped launch a song which was written about his daughter. The lyrics ask her not to give up hope.

"Your father misses you, your mother thinks only of you. Wherever you are, don't give up, don't give up.''

The single "Cedrika'' was written and composed in French by a singer who prefers to be known as Stev.

It has been distributed to French-language radio stations in Quebec.

"I myself have a little girl who is five years old and the story of her disappearance has affected me a lot,'' he said. "My biggest strength is writing and music and I used that talent to bring some comfort to the family.''

Stev said the song also tells young people to avoid strangers who are being too friendly.

The 28-year-old singer from Shawinigan has had to defend himself from accusations he is capitalizing on the girl's misery.

"It didn't go over well and I was called an opportunist, but when I had a news conference with Cedrika's father, Martin Provencher, it cleared things up,'' he said.

"It was the family that gave me contacts and helped me get the song on the market.''

He said about $2 from the sale of every single will go to a fund which has been set up to help the family look for their daughter.
