The family of Dylan Redwine may never know how the Monument teen died.
Redwine, 13, went missing while visiting his father in the mountain town of Vallecito in southwest Colorado over Thanksgiving break. Human remains found along a rugged road near his father's home last month were identified last week as Dylan's.
"So far, the items that have been found are not enough to make an actual cause of death or manner of death," La Plata County Coroner Jann Smith said in a telephone message.
"Until investigation goes a little further, we may not know exactly what happened to Dylan," Smith said.
Authorities have been tight-lipped about what they found during a five-day search along Middle Mountain Road in Vallecito.
A spokesman for the La Plata County Sheriff's Office did not return a call for comment.
Dylan's death is being treated as a criminal investigation.
"Early on, we held out a lot of that this was a runaway situation," Lt. Ray Shupe, a spokesman for the Durango Police Department, said last week.
"As things progressed, it became pretty clear that this was going to be a kidnapping, homicide or some kind of death," he said.
