COLORADO CITY, Texas -

It's been nearly a week since a 13-year old Colorado City girl disappeared, according to her parents.

Sunday the search is growing as well as the reward to find her.

The Dunn family is pleading for anyone with information about their daughter to call police.

Hailey Darlene Dunn's parents say she disappeared on December 27th and had plans to go to a friend's house, but never made it.

According to a flyer sent to us by a Mitchell County radio station, an anonymous reward that began as $1,000 has now grown to $10,000 and is being offered for Hailey's safe return or information.

Police still have not issued an Amber Alert because they say there was no evidence that she was abducted.

Sunday, hundreds of family and friends came together to get out the word about Hailey's strange disappearance.
