A Grand Junction teenager, missing since December, died from "mixed drug intoxication," according to a report from the Mesa County Coroner.

After completing its examination, the coroner determined that 18-year-old Kelly Myers died from a mixture of drugs, but the manner of death is undetermined at this time.

The Daily Sentinel reports that two men, 47-year-old Raymond Cordova and 30-year-old Eduardo De La Cruz were named as "persons of interest" in the case by the West Valley City Police Department in Utah. Both men are being held in Mesa County on drug-related charges and suspicions.
