A teen heading back to her home in California allegedly never made it back, with authorities saying that the last time she was seen was at a layover at Denver International Airport.
The National Center for Missing and Exploited Children said that 15-year-old Harper Cadman went missing at the Denver International Airport on Jan. 30.
"Harper never got on her flight back home and is believed to still be in the Denver or Boulder, Colorado, area," an announcement from the National Center for Missing and Exploited Children said.
The organization said that the teen was last seen when she landed in Denver around 8:27 a.m. on Jan. 30 for a layover on her way back to California.

In a Facebook post, Cadman's mother, Ari Petronelli, wrote a heartfelt message about her daughter's disappearance.
"I am sick to my stomach writing this, and I never thought that I would ever have to post another missing flier of my own child but if anything this last year has taught me is that life just doesn't make sense," Petronelli wrote in a Facebook post.
Petronelli explained that her daughter was heading back to their home in California from Montana, but never made her United Airlines connecting flight.
She said that her daughter was participating in a mental health treatment center in Montana at the time of the incident.
"As many of you know, Harper was in treatment for mental health last year and while being transferred from Montana back to California, she disappeared during her layover in the Denver airport on 1/30 at 8:30 AM from a United Airlines flight," Petronelli explained.
Cadman is described as being 5’7" and around 115 pounds.
She has blue eyes and black dyed hair. Her nose is pierced, and she has tattoos on her waist and the middle finger of her left hand. She also has braces.
Her mother said she was last seen wearing a white True Religion sweater, black leggings, and black boots. She had nothing else with her while traveling.
Officials believe she is still in the Denver or Boulder areas.
According to her family, she does not know anyone in Colorado.
