State and local authorities are anticipating the completion of a toxicology report for Dylan Parker, which could arrive as early as next week and potentially reveal additional information about what led to the Kellogg teenager's recent death.

Parker's cause of death has been listed as hypothermia, according to Shoshone County Coroner Lonny Duce.

Parker, 18, went missing after attending a party on Two Mile Road in Osburn on Saturday, Jan. 11. His body was found 10 days later in a snowy, heavily wooded ravine in the Two Mile Gulch area by two men riding all-terrain vehicles who were searching for another ATV that had fallen down a steep hill.

An initial autopsy report completed by the Spokane County Medical Examiner's Office did not reveal any signs of foul play, the sheriff's office said in a press release last week. The press release stated that toxicology results would not be available for up to two weeks.

Shoshone County Undersheriff Rod Plank said he is hoping the toxicology report will arrive by the middle of next week. However, Duce was more skeptical of that timeline and said on Friday that the results could take as long as eight weeks to be completed.

"The actual fluids from the body are sent to a separate lab from the coroner's office," Plank said Friday.

The Medical Examiner's Office in Spokane covers the five northern counties of Idaho along with Spokane County, which slows down the completion of a full autopsy report that would include toxicology results, Plank said.

The Shoshone County Sheriff's Office has taken the lead on the ongoing investigation of Parker's death, while Idaho State Police have acted as an assisting agency.

ISP Detective Michael Van Leuven said that his agency was asked to process the scene where Parker's body was discovered, but that the county is leading the case.
