A 16-year-old girl from Chattanooga, Tennessee, who went missing in October is now believed to potentially be in a different state.

According to an update from the National Center for Missing and Exploited Children (NCMEC), Daphne Westbrook, who was last seen on Oct. 6, could potentially be in Colorado or Georgia, in addition to the greater Chattanooga metropolitan area. A local report from Chattanooga also noted that Westbrook could be in New Mexico.

No rationale was given for why Westbrook might be in those states.

Westbrook is also suspected to be traveling with her dog, Fern.

Westbrook was last seen leaving her father’s house in the area of Saint Elmo, telling her mother that she would be walking the dog. Her mother later received a strange call from Daphne wherein she insisted that she was not missing. Police later traced this called to the area of Dalton, Georgia, a little over 30 miles southwest of Saint Elmo.

Westbrook’s car was found near the Glen Falls trail at Lookout Mountain, an area nearby to her father’s house. Rangers working at the mountain estimated that the car had been parked near the trail for at least a day.

“If she was just going to run away, why wouldn’t she take her car?” said Westbrook’s mother, Rhona Curtsinger. “And she is not using her phone. Both of those things are terrifying, especially with the Internet the way that it is.”

Westbrook is described as 5-foot-3 and about 110 pounds. She has brown eyes and light brown hair.

Anyone with her information regarding Westbrook’s whereabouts is urged to reach out to either the NCMEC at 1 (800) 843-5678 or the Chattanooga Police at (423) 698-2525.
