Hailey Dunn was last seen at 1804 Chestnut in Colorado City at 1 p.m. on Monday, December 27.
At this point, Dunn's disappearance is being treated as a runaway.
"There is still no evidence of foul play or abduction," Colorado City Police Chief John Bivins told the Colorado City News.
Over the last few days, friends and family have posted numerous messages on Facebook and changed their profile pictures to images of Dunn.
"Dunn is a white female, 5'1' with hazel eyes and brown hair and pierced ears," reads a posting by Candi Garrett on the KRBC Facebook page. "She was last seen wearing navy blue sweat pants, a short sleeve light colored T-shirt and pink and white tennis shoes. Anyone with any information is urged to contact the Colorado City Police Department by calling 325-728-5294."
A video was even posted on YouTube pleading for Dunn to come home. (you can view that video by clicking on the video player above)

Colorado City authorities confirmed Friday that a reward of $4,500 was being offered for information leading to Dunn's safe return. According to KVMC/KAUM Radio, that reward has been increased to $10,000.
