THE DALLES, Ore. (AP) – Authorities say two people and a dog were found dead in a camper trailer outside The Dalles and that carbon monoxide poisoning may have been a factor in their deaths.

Wasco County Sheriff’s detective Sgt. Jeff Hall says Yamhill County authorities on Tuesday requested help to find 47-year-old Deon Louise Patterson and 48-year-old Brian Thomas Paulsen who had been reported missing by family members.

Hall says deputies went to an area outside The Dalles where Patterson was known to camp and found Paulsen’s pickup and camper trailer on a property near a cabin.

Hall says deputies found them dead in the trailer along with a dog. He says evidence suggests carbon monoxide was a factor.

Law enforcement and medical examiners are investigating.
