The Colorado Bureau of Investigation (CBI) has issued an alert for 16-year-old Kateryna Michal, who went missing on Sunday afternoon in Elizabeth. Known to her friends as "Katie," she was last seen around 4 p.m. in the 4200 block of Ovydel Circle. Described as an indigenous Alaskan Native, Katie stands at 5 feet 3 inches tall, weighing 105 pounds with brown hair and eyes. Her last known outfit included a gray sweatshirt, black leggings, and slide slippers, as reported by Denver7.

Concern is heightened for Katie's well-being, as it has been mentioned that she depends on medications, which "she does not currently have with her," according to the missing person poster shared by the CBI, as obtained by KKTV. The lack of her essential medications underlines the urgency of her search.

Furthermore, the CBI has upgraded the nature of Katie's case to an Endangered Missing Alert. Following the provided description, law enforcement is deeply concerned for her safety. Every effort is being made to locate her as promptly as possible, with the hope that the community can assist in these endeavors. Katie's description and related information have presumably been widely disseminated across the state, encouraging anyone with knowledge to come forward.

Members of the public are asked to be on the lookout for Katie, who, dressed in described clothing, might have seemed distinctly unprepared for the elements or a prolonged absence from home adding to the acute concern felt by authorities. In a move that underscores the severity of this missing person case, the Endangered Missing Alert was circulated, as per CBS News. Anyone with information regarding Katie's whereabouts is strongly urged to contact the local law enforcement or the CBI immediately, as swift action could prove paramount in ensuring her safe return.
