By the time police got to 38-year-old caretaker Renee Radziwon, she was already dead, mauled by an exotic cat.
"It's dark, this is a remote area, the area in has a wild look to it," said Sgt. Robert Wurpes, Clackamas County Sheriff's Office.
Investigators don't know if the big cat's enclosure was left open or if it escaped.
Messages left by ABC News to Wildcat Haven had not been returned.
It's just the latest attack at a wild animal refuge.
In March, 24-year old intern Diana Hanson was killed by a 550-pound lion, which escaped from its feeding pen at a California sanctuary.
And in June, 21-year old caretaker Marissa Dub was critically injured when a tiger attacked her at an Indiana animal refuge.
SOT: Rebecca Micelli, Dir. of Animal Care, Wildlife Sanctuary in Colorado "These are wild animals and even in situations where people who would know lots about them or work with them, that at the end of the day, they are what they are, which is wild predators," said Rebecca Micelli, Dir. of Animal Care, Wildlife Sanctuary in Colorado.
Authorities in Oregon say all the cats at Wildcat Haven have been accounted for.
