On the afternoon of September 17th, an employee of the concession-operated Mazama campground discovered two bodies inside a tent while checking on an overdue campsite payment. Investigating rangers found the bodies of 25-year-old Alaethia Christensen and 27-year-old Tory Christensen, both of The Dalles, Oregon. The tent was tightly closed and it appeared that a propane camping lantern had been burning inside. A toxicology analysis revealed that carbon monoxide poisoning was the cause of death. The couple is believed to have died sometime during the night of September 14th. Rangers and an NPS special agent, assisted by the Oregon State Police, are continuing the investigation. Autopsies on the two victims are expected to be completed later this week.
